We had to bang it to get color back. Banging the set jarred the discontinuity in the solid-state circuit that did color decoding. With modern manufacture, that sort of nonsense is much less likely, but given that moving the iMac into a different location made the problem impossible to replicate lends credence. One correspondent realized that the issue was absolutely basic: He removed the dust, and a thermal sensor stopped shutting down the display. You can use a vacuum brush attachment or compressed air. If you use compressed air, remember to power down the Mac, and place it in a position so that you keep the can of air upright.
Otherwise, you can spray liquid out of the can that evaporates so rapidly it causes freezing on surfaces it touches, and can damage the case and the screen. Reader B. That gap caused periodic screen blackouts. Pressing on the affected spot could restore light temporarily. While he replaced the screen, the problem came back.
Waking it would re-activate the backlighting, at least temporarily. Running it with a dimmer setting for screen brightness also worked. Tye found that an Epson printer that used Wi-Fi for network connections appeared to cause an iMac blackout. We know that improperly shielded monitor cabling can allow Wi-Fi to affect displays and even system crashes, so this is another variable to try to eliminate when troubleshooting.
Email yours to mac macworld. Troubleshoot and recover a Mac with a failed drive. I hear fun noise. Mac is run. But black screen. I try. Both solution mentioned nothing help I try other. Solution from web same. Any help will be appreciated Thx. This is now a frequent problem for users of Mavericks and Yosemite, I tried everything with my Macbook Pro but nothing worked. Even reloading Yosemite using one of the recovery tricks.
Finally I decided to Pay for Apple Support and was pleasantly surprised to find that there is no charge for help with this problem on these two operating systems. The first technician took me through all the things I had done, trying to boot into Safe Mode, trying to boot into Recovery Mode even getting to the failure point and entering my password in case it was just hidden. He then got a senior tech on the line and she said she could fix this in 10 mins as it was a known issue.
She had me power on and hold down the command and S keys. Keep holding the keys until the screen fills with a lot of Dos like code. At this point she dictated 3 lines of text with things like plst and library etc, sorry I cannot remember much of it. Then we powered on and off and again the screen went black but she told me to just keep hitting a few random keys and lo and behold the system came back up and is now OK. The problem as I understand it is a corruption in some plist logon type files which she had me delete and on the next boot the Mac rebuilds them correctly.
Good Hunting! I am reading through my error logs, and I am seeing this same plist error. I just do not know how to fix it. Guess I will call Apple and hope that somebody there gives 2 chits enough to help me fix it properly this time! Thanks for the post! Thanks for the suggestions, but none of these methods have helped.
Gotta go see a genius I guess. I decided to do a new clean installation of Yosemite and then restore my userdata. Everything went fine and I was happy with my newly installed MBA until a couple of days ago. Again I got the black screen after waking up from sleep: Anyone have an idea what the issue can be? Had this issue but called apple support to fix it in 2 steps. Steps to solve issue MacBook turns on makes the sound but no display or cursor, just a dark screen. Thanks, me and the oldest boy rolled thru all other suggestions, until finally this one worked.
Thank you, thank you!!!!!!!!!!!!!!!!!!! Thanks a lot!! This worked, after the second noise the screen was still black then I forced it to shut down, turned it back on and the problem was solved! Thanks for sharing your solution, after trying several methods this was the definitive solution to my case! Thank you so much! I thought I was either gonna have to pay a TON of money to fix my computer, or throw it away! This worked for me! This one worked!
Happened to me just after using the migration assistant. Guessing it could be related to dual monitors on the old Mac Pro, but not sure. Thank you!! Worked first try. Saved my day! Will never panic again when I see the black screen and hear the fan working so hard. Thanks again!!! Yippeee OMG you saved my life! Fingers crossed it will be ok now for ever! I think the second tip is working for me! My computer is still turning back on.
Do you think this problem might have been caused by recently installing fluux that program that dims the blue light on your computer at night? Wow jeszica!!! You are my life savor!! The only result that worked for me after searching all thru YouTube and Google for help! Thanks Jeszica!! You Rock! After trying all other suggestions as they come, yours work like a charm. Just had a customer who had this issue, turned on the MBP The flashlight on the screen in a dark room reveled the login page as others sites have stated, once I entered the new password I created on other attempts to fix the issue I was directed to the Keychain page where I entered the orignal password in the update Keychain password supplied by the customer and viola, straight back in and restarting as per normal.
No other issues and the laptop screen lights up as usual on startup and sometime when taken out of sleep mode but goes dark again within minutes. Tried all of the resets, no go. Any other suggestions out there?! Thanks OSXDaily! There are a few factors to the problem listed above, and the solutions for each of those should definitely be tried at least three times. I was panicking when none of the solutions worked, and then I realized my MacBook was severely overheated.
Nearly scalded my hands holding it. I started it up, removed all peripherals, put it to sleep clamshell mode and left it on the floor for 5 minutes cos all the cool air-conditioning made the floor really cold. Then when I picked it up again after it was all cooled, the screen just… worked. No flaws. Here are some points to consider:.
Turn it off, or turn it on and put it to sleep. Apply something cold not ice please, more like blow at it with a fan or something to the bottom of the MacBook. Again, check your MacBook and take care of it. Try all of these at once when your MacBook is at optimal working temperature. Then schedule a day to bring it to an authorized Apple Service Provider.
Yes, it got that bad…. But I learnt to understand and fix this MacBook on my own. Surely, prevention is better than cure. This aluminium unibody does a horrible job at ventilation. So the air comes out from the keyboard, apart from the exhaust in the joint. Keyboard covers are the one-way ticket to suffocating your Mac. Way to go Apple, sacrificing so much for aesthetics. This happened to me today. I went to the Apple store and they had a two hour wait. I was so tempted to just toss the computer in the trash. I got on my iPhone and found this solution.
Works fine now. The second sequence worked for me. Thank you very much for the the. So here it is, and from the bottom of my heart: Same issue, took me a few days to resolve. Try this sequence, stopping whenever you get the white screen and chime to display upon boot up. Get it back to grey screen and follow these instructions: Repair until you get the OK, then go back into disk utility apps repair and run it in there a few times. It worked for me, I doubted it but it did. Once i just smashed my keyboard after a few hours and that somehow worked too… do not suggest that last one.
Upon getting it to load, have a hard drive ready and start grabbing the important stuff. Best of luck. I tried rebooting with option command p r and it made the chime. Any suggestions? Hi- have tried all and this is not working for me. My MacBook pro was purchased in so very old. It starts but black screen. I have tried all suggestions above. Any one have anything else to suggest? Hello Lisa. I am having the same problem. By looking at the date you wrote this post, I believe the problem is already resolved.
Any advise on this? Omg thank you so much Jessica it finally worked for me! Unusual to have problems with Mac!! Obviously a fault with the Apple software!! Thank you Jeszica!! I tried all suggestions and nothing worked until I pressed power and then held option, command, P,R until the power sound came on about 3 times and then finally the screen restored. Had to get a torch to shine it at the screen though to get through the secure login! What is previously black becomes just about visible. It worked!!! I refer to the original suggestion of control option shift power button, followed by normal press of power button.
Lately it just kills itself to black. Many thanks, especially as am about to go on a work trip and need my computer! Rebooting the PRAM worked for me! Thanks guys! I was wondering what the heck as my Macbook Air is only two days old!! Thanks again! I was wondering what happened to my Macbook Pro is only 15 days old!! PRAM method worked after trying the previous two.
Thank you. So it seems anything will work at some time or other I think CloudyZack has it nailed these get too HOT wait till it cools down then try any of the methods listed I am going to drill some holes in mine just under the fans better ventilation is sure to help. I tried the methods described with no luck. He had me:.
It is ONE line with a space between loginwindow. This worked for me and got me to the login page. The tech said the code just sets your computer to find the last working startup. Hopefully it will continue to work: Good Luck! Mischa, Thank you so much! Your code here just got me my computer back!!! I had a black screen and could see pointer, but that was it. I followed your instructions and bam, the login screen came up!!! So excited!! The above method worked for me. Nothing worked.
I even reinstalled Yosemite from the recovery option twice and nothing. But this last option worked. Thank you a million. I had this problem crop up after I restored my system from a Time Machine backup. The above was the fix! I tried several times all 3 solutions: Thanks so much. Worked great. Nothing had worked and was loosing hope until I found your post.
Thanks a ton. After fiddling with brightness had that issue before I found this article and tried 3 solutions one after the other. Thank you so very much I went through all three of the props that was display and the last one worked appreciate you a great deal. I had the same thing happen and tried all the steps, 1. Still, black screen. Black screen. Still the black screen. Still black screen. Back to recovery mode, reinstalled mavericks. Still, no success. In conclusion, I have tried everything but the apple service, the black screen arrived out of nothing and remains here, tormenting me.
Ok, so as I said, non of the 7 solutions above worked for me, here is what did: I found this solution on another troubleshooting forum which dealt with the same problem. Here are the steps that brought me back everything exactly how I left it: Turn off your Mac by pressing the power button until your Mac shuts down. Turn your Mac back on and hold the shift button.
You will see a loading bar fill up and then your screen will go back to black with your cursor visible. Enter the first letter of your user name and hit enter 4. Enter your password and hit enter 5. The beach all will start turning. If your Mac goes to sleep mode wake it back up as usual. An install window will pop up, for an update. Follow the steps to set up the installation. You end up back at your home screen as you left it. I hope it helps! Good luck and hang in there!
I had the problem described above but none of the solutions worked, and then when I moved the MacBook to connect an external monitor the problem disappeared. Now I know my circumstances are very rare. I had stacked the one I was fixing on top of the other one with the lid closed. So the top MacBook thought the screen was closed and so, turned it off. Lift the top MacBook off the bottom one and the problem goes away. This was driving me crazy!!! Scott, you saved me and my macbook: Tried everything and was just about to give in for the night and read your comment… Thanks very much!
After attempting ALL of the suggested fixes multiple time I finally called tech support. Ellen had me hit the power button and then hit the shift key which started the computer in Safe Mode. It brought up the login dialog box and once I entered my password the computer brought up my regular startup screen. I clicked on the apple in the top left corner of the screen and then hit restart. It brought up the login screen again and once I logged in everything was back to normal — running real slow after loading Yosemite.
At least now I can do my taxes: I tried all three options a couple of times without luck. It worked. Interestingly when the screen was happily visible and I could log on a critical is update was ready. The one that seemed to work so far is a hybrid of two. In safe mode the bar finished loading and I logged in, retarded and the Mac asked me to install a software update, I did. This is the second time it happened on startup. The last PRAM reset worked like a charm and booted my mac to life!
Sometimes the SMC worked, sometimes the PRAM zap worked, but mostly the old unplug the machine from power, close the lid and wait a few minutes was the key for me. When I booted into safe mode I was able to backup the drive and use a second monitor for a number of hours, so Apple support walked me through trashing a slew of preference files and while they were watching my screen it happened again- black screen at startup.
So they recommended I reinstall the OS.
I went for a really clean install and erased my already backed up drive and started the 2 hour Yosemite reinstall. I must have missed a crucial step because when the machine restarted I saw a folder with a question mark, and when I tried to restart into recovery mode all I get is the chime and a black screen.
I made the trip to my nearest Apple Store and was told about the video card replacement program. It started a few days later here in Japan, so I was told to call Apple on the start day and report my problem. The next day Sat. I am happy to say my external monitor once again works, and I have had no re-boots or black screens knock on wood! Thank you Apple better late than never! The only solution that worked was to use time machine, had a backup on a hard disk.
Wish you success. The exact issue I was experiencing was that my machine would boot to a black screen no Apple logo and not display the login screen until I slept the computer and woke it back up. After trying everything mention above , still got black screen on my MacBook pro. It worked and I got my MacBook screen again and got relief: Thank goodness this worked. None if the three worked for me. My screen went black after I had the Mac book pro standing on edge and it fell over only a few inches to laying flat.
When I reboot I get a lighter but still black screen. Did I frie some kind of screen connection? I have read all of the comments here and attempted all the solutions and nothing works. My screen is black. However, the white light comes on in the front when the power button is pressed on. So when everyone is describing a black screen and then describing one of the solutions, are you describing a screen that is actually clicking ON but has only a black background or a black screen that appears to be off?
Again, I have attempted every solution described above and nothing seems to work. That black screen scared me as I just got my MacBook 2 months ago! Thanks so much for the tip — saved my weeks outlook! This is the second MacBook Pro Retina to do this to me. I bought my first one in December , it did this within a month. That was about a month and a half ago and it just did it again. I tried all three of the above solutions and was so happy when the PRAM reset worked!
I have a pro that this happened to today. This morning I tried all of the different solutions posted here and elsewhere, including the pram reset a number of times without success. But after leaving it for a few hours and then guessing when to hit pram as I wasnt getting chimes, it has eventually worked.
I tried the first trouble shooting option and I heard the noise it makes and the fan start up then the screen flickered and it shut off. Now it wont turn back on.
A Solution for MacBook Pro Booting to a Black Screen
I do not know what to do at this point. Thank you so much for this article, third option worked perfectly!! Was having a mild panic as Mac exactly 1 year old today so warranty typically just finished. Thanks for the fix, very grateful. Thank you, thank you, thank you!!! The first 2 suggestions did not work for me but the second one did.
[Solved] How to Fix iMac Screen Goes Black - iMobie
This happened to me once before and the genius bar fixed in in 10 minutes but this time I am in Vanuatu where there is no genius bar. The third suggestion worked like a charm: I thought about all the documents I just saved and how much time it was going to take to re-write them. Hmmm…I should have at least printed them. A big lesson! I tried everything holding all kinds of combinations of letters with all my fingers twisted but nothing worked until I did the PRAM Reset exactly as said.
My husband put his finger over his mouth…. Thanks so much whoever from genius bar posted all the solutions. Option 3 worked for me. Just keep in mind, it may take a little while to hear that second home. Try and be patient. I think I was a bit slow off the mark the first time I tried it. The other options were tried with no success. Thanks for the help. The first option you guys had with the shift control option power button hold worked for me!!! Thank you!!! Black screen appeared after downloading the latest update. I noticed when I picked up my laptop the bottom of the case was hot.
Tried the other options with no luck but PRAM reset worked first try. The last, the PRAM reset worked for me. I just got this computer in January, and am a little upset. This is my 5th Mac and the first time I have ever had any problem. The PRAM reset, whatever that is, worked. Thanks so much for posting this fix, it saved my butt. I can open my Mac but right after I entered my password it goes black after. Can anyone help me.
Nothing mentioned here worked but i tried my luck and here is what worked for me. All i did was remove the battery the. Put it in again. Hope it helps someone. Same as above.

The other options did not work at all. The third option worked for me. Had to do it twice though. Totally freaked out when I had this problem and your second solution did the trick!!!! What a nightmare, pain in the boot. Not sure I agree the black screen is a rare problem, since if you are unfortunate enough to have it happen and search for a solution it seems MANY people have had the same issue.
The pram reset worked for me. Very helpful so thank you. I have the MacBook pro retina, 13 in, mid model. So many thanks. Now off to watch some Netflix lol. MacBook Pro retina bought new in September Nothing works and I tried everything that was suggested. The display part seems to be dead. I used my notebook then left the table closing it. Came back an hour later and the screen is dead. I made an appointment with Apple but the earliest one available is on Tuesday. Apple sucks. PRAM rest option worked for me but you have to press the keys at the same time accurately. Thanks for the post.
The PRAM step worked for me. Can anyone help? PRAM worked for me — interesting that son also playing with brightness the night before this happened. The last one did luckily thank you so much I was so worried. A very helpful solution. Thank you so much for the very effective solution. The PRAM reset worked, thank you! I tried each one on the list got nervous as each one failed. I held my breath at the PRAM reset and was thrilled that it worked. None of these worked for me. So I tried plugging it into external monitor and still no picture even on the external monitor, so when I unplugged the hdmi the screen popped back on.
That makes zero sense but okay! None of these have worked. Try to turn up the brightness. Have a similar problem, tried all the tricks mentioned above but screen remained black, then finally tried plugging in a TV scree on HDMI and voila. Managed to get the machine started and copied all important files… but laptop screen still black. Macbook Pro with retina or El Capitan. The third aolution worked… I was teady yo try a hammer, thank you so much! Never had that before Yosemite This sucks so much — I can hardly work!!!
You are describing an issue with some OS X The third option worked for me on my MacBook Pro refurbished. I followed the steps and then turned it off and on again once more. Now I can see my screen. Big thanks to the author!!! Thank you so much!!! I was definitely in panic but third one helped me! Thank you soooo!!! I tried every effort but no way, that was very frustrating to me. I went home started looking through the net, fortunately, I have tried your solutions. The third step fixed my MacBook, thank you for the good advice! I tied the first two with no luck but the PRAM thing worked like a charm.
Had this issue on my MacBook Pro. After numerous reboots using the shift key, nothing worked. Found this site and tried option 1 and 2 to no avail. Option 3 the PRAM reset worked finally worked. A big thank you as I was ready to throw my computer across the room. The problem occured after Yosemite Hope problem will not occure again. This happen to me and the Pram restart worked… Thank you! I was updating when it went black.
I tried all three solutions and none of them worked… I was really, really sad. Guys i found a really easy fix for my screen going black. I was using a foam case which had a magnetic clip. This was then causing my macbook to think the lid was closed and the screen would then go black.
This tip on osxdaily. I tried the first couple of suggestions with no result, but when I tried the PRAM reset, worked like a charm! No more black screen boot! Thank you, thank you, thank you! I tried the first two tips as well as another I found on a different site with no success. Then the PRAM reset worked!! Just got my MacBook Air a couple of months ago, but was starting to think it was already busted.
Thanks so much! By using a combination of the suggested fixes I was able to get my MBP up and running for a couple of weeks to a couple of minutes. Apple has determined that a small percentage of MacBook Pro systems may exhibit distorted video, no video, or unexpected system restarts. The program covers affected MacBook Pro models until February 27, or three years from its original date of sale, whichever provides longer coverage for you.
The replacement part he called it a logic board arrived this morning, and I picked up my computer this afternoon. PRAM reset worked!! You need to make sure you hold down the keys all at the same time and right after you hear the boot chime. Thanks so much I was freaking out. After attempting the first 2 solutions, the 3rd one worked for me.
None of them worked for me. I got the Macbook Pro to Apple store today. Genius guy checks for failures. And told me there is a problem with motherboard. And it is must be changing. They will change it for free because it is an factory production problem. Sorry for bad english. Third option worked for me on my MacBook Air mid model , I cannot thank you enough for saving me! Thanks so much for this …I was in a rel panic when I opened my MacBook to find a black screen!!!
Bonus Tip: How to Remove Mac Junk with MacClean
For no known reason I might add. Pitch black when booting, and PRAM reset worked! Thanks mate. Please help! Nothing worked for me. Afraid of it now: MacBook pro Just got my new macbook pro for less than two days and had everything updated. Then it booted into black screen with a chime after did a migration through firewire. I tried every combination of keypress after power on, no luck. Finally, the PRAM reset solved my problem. Big thanks. Thank you so much for this post!
Finally after many many times resetting the pram worked. Thx for the trouble shooting solutions. The 3rd option is just a right medicine for my my coma air book. Just woke up. Thx for ur research. It save time and money both. I tried all of these fixes mid Mbp retina but it still was black screening.
It was out of warranty, but somehow Apple covered it. Sounds like an internal known-issue. Tried all three tips to no avail. Finally tried disconnecting the power cord. Then held the power button down for a few seconds again and … Shazam! The three solutions did not work for me. But closing the laptop while on, waiting about a minute and then opening solved the issue. I can hear the hardrive spining and the power light is on but nothing on the screen. Does anyone know what the problem might be.
Is it the screen or the graphics chip. How do I find out. Mischa, who posted February 11, Do you mind to contact me via email? I dont really understand the instructions you give in ur comment. I hope you can give me step-by-step instructions on how to do the coding. You have to do it hockey and precisely.
I had the same issue with black display after boot. I could only hear the chime sound and everything went black. My macbook pro retina model boots up to a black screen. I tried everything here and thought it was a logic board failure. But, a trip to the genius bar fixed the problem in five minutes. It was some sort of connection issue between battery and display. He unscrewed the battery secured the connection and boom everything is solved!! Unfortunately the resets are not working for me, I will contact Apple to solve it at the hardware level as mentioned here before, but in the meantime I can get my internal screen back this way:.
Close the lid of your computer 3. Open it again 4. Plug a display adapter in the mini-port, wait for a couple of seconds 5. Unplug it again. OMG this worked for me!!! Then I remembered that I had unplugged my external monitor and closed my laptop just before this black screen issue started, so I figured maybe this would work and it did:. Then unplugged pulled out mini-display port from MBP and to my complete surprise my login screen popped up! I had this on moving my MacBook Pro and was a bit panicked — working down the list with no change I was really worried — fortunately the PRAM reset listed as the final option worked!
Great stuff and thanks for this: Like Joe near the top said, none of these worked for me either. Any other suggestions? As is mentioned in the article, if you have tried all of these solutions and the Mac screen is still black, it boots to black, and the screen and external displays are always black, you may have a hardware problem or a bigger issue with the MacBook, iMac, MacBook Pro, MacBook Air, or Mac Mini. In that case, you should take the device to a repair center and have them determine if there is hardware failure.
Any Apple Store can diagnose hardware problems for you. Best of luck! Thank you thank you… New to MacBook Pro, only had it a week, black screen prior to urgent work commitment this morning and thought what on earth have I done… Tried all three suggestions twice, second time around PRAM reset fixed it….
Saved your file and hope it is not needed again any time soon. Gys neither of the above solutions helped me. I use both windows 8. But I can see the cursor moving over there. No problem with Mac OS. Can you just help me out gys..!!! I have a late MacBook one of the white ones. My issue is that the screen goes black pretty such straight away on booting: In my case, its Snow Leopard.
If I reboot with the installation CD in the laptop, the backlight works!! However, partway through the install the backlight goes out and the problem is returned. This does tell me one thing: I think that the next thing for me to try is installing to a new or zeroed-out hard drive. I was wondering whether anyone can add anything to this.? Anyway, I will update this reply with progress updates for the community.
This finally worked — but not the first time I tried it. None of the other options worked. PRAM reset worked for me. I have a new MacBook Pro. I am so glad I found your tips. Hey guys. I just encountered this problem with my MacBook Air. I used it last night and closed the screen just fine. When I tried booting it in the morning it booted to a black screen. Please please please help me. Thank you so much. In my case, none of the 3 solutions worked, and I was afraid my mac was dead, completely.
During my 1st attempts, I had numerous external cables connected to my mac, like headphones, keyboards, mouses, etc. Thank you u so much for this article — solution 3 did the trick in my case! I had the blank screen after leaving the MBPR in a deg. When I opened it again, I found it hat shut itself down. I tried all the methods here several times without luck.
After leaving the laptop unplugged, open and on but with a blank screen for a few hours, I closed it. When I opened it again, the login screen was displaying again. My guess is that it was a battery controller issue that shutdown the machine Monday evening at due to high heat or low power running fan? My computer has been sitting for literally YEARS because I thought- even after bringing it to a Mac expert friend- that the screen was dead forever.
I wanted to try one last time to connect it to an alternate screen and when that failed, I googled black screen and found your page. I used the key code s! Opening this computer is like a time capsule! Miraculous and thank you! I must say, after a weekend of camping, coming home and totally crashing in the bed and waking up 12 hours later at 4 a. Thanks a lot!!! I had the same issue with my iMac and Apple support walked me through the fix yesterday…. Shut the computer down by holding the power button for 10 seconds 2.
Restart the computer and press shift at the same time until you see the progress bar start moving 3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter. After a moment, you should see the spinning beach ball 5. Let it finish. After that it should go to your normal desktop and the issue should be fixed. If your screen goes pitch black during this process, hit the space bar. From https: None of the solutions worked. Not good enough, complete waste of my time.
Heard good things about Apple so I bought one but will never again after all this rubbish. Cheap laptop that looks good. I tried your sequence of steps 1, 2, 3 and then again 1, when my Mac finally booted up with display!! In a diff sequence. I shut my mac down. I was pressing the keyboard sequence and then pressed the power button. Worked amazeballs. The chime came and then the screen went completely black looked like it was turned off and then a louder chime followed with apple logo then the log on page. Tried the first two options and was beginning to lose hope but the third one worked a treat….
And to add to my previous post, my MacBook Pro now boots up so much quicker than before….. The third solution worked for me, PRAM reset! Some of us have much more pressing issues that are causing the same problem and those of us that do are obviously unable to fix it using the same method. Good gosh. We get it. My first Macbook after running from Windows 8. She is not technical, so I have to handle it. Had to use Google to find this webpage, again. Both times it was the PRAM reset that resolved the issue.
It would be nice to know exactly what causes this issue. I was on my phone searching for the next thing to try when the apple icon screen popped up.
