65nh84 Picture Goes Black and Back to Normal
I am having two problems with my set. When I turn it on the picture has vertical lines through it and faded color until it warms up for a minute. Then after a few minutes the picture will go black flip to a black center with white bands on the side and back to all black. It does this a few times and then back to a normal picture. A couple minutes later, if that long, and repeats. The set is doing this on all channels and when using my DVD player, with cable and antenna. I have read that the scan converter is the cause of the vertical lines however it is no longer available. Is this the most likely cause of my problem. If I can not get the parts where can I get the schematic to replace the discreet components myself. I doubt its worth the cost of sending it out for repair. I have repaired many CRT TVs in the past as I am a degreed electronics eng. Please point me in the right direction.
Thanks for your help.
1. Close all inactive apps in the Task Bar. Double-click the Home button and hold apps down for a second or two and tap the minus sign to close app.
2. Try a reset. Hold the Sleep and Home button down for about 10 seconds until you see the Apple Logo

2nd monitor keeps going black and back on. How to stop that?
Since installing MAVERICKS the 2nd monitor does not stay up all the time.
It will go black for a few seconds and then comes back. WHY?
How to stop this?Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

The ipad screen is white. Holding buttons didn't work so I restored it on iTunes. When I press home and on switch, the screen is white, goes black then back to white with no logo at all. Can't get past the white screen. This happened after running app updates. Is there any fix besides going to Apple store? In iTunes on computer can see what is on there. 16GB OS 7.1.1
FORCE IPAD INTO RECOVERY MODE
1. Turn off iPad
2. Turn on computer and launch iTunes (make sure you have the latest version of iTune)
3. Plug USB cable into computer's USB port
4. Hold Home button down and plug the other end of cable into docking port.
DO NOT RELEASE BUTTON until you see picture of iTunes and plug
5. Release Home button.
ON COMPUTER
6. iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes.
7. Select "Restore iPad"...
Note:
1. Data will be lost if you do not have backup
2. You must follow step 1 to step 4 VERY CLOSELY.
3. Repeat the process if necessary. -
Have most recent macbook pro connected to thunderbolt via thunderbolt cable. Occasionally when I close my laptop the thunderbolt display goes black and does not come back on---even in response to keyboard. Help
Hello QuinnDev,
Thank you for posting in the Apple Support Communities. It sounds like you are trying to use your MacBook Pro with a Thunderbolt Display in closed clamshell mode (MacBook Pro closed), but sometimes the display doesn't stay on. I found an article that talks about closed clamshell mode. You would have to fulfill the following requirements to use your display this way:
Requirements for closed display mode:
Power adapter
External keyboard, mouse, or trackpad
External display
You can find all the steps and the full article here:
Mac notebooks: How to use your computer in closed clamshell (display closed) mode with an external display

I hope this helps!
All the best,

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.
I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly... -
Apple TV 2 picture goes black for a second every now and again
Apple TV 2 picture goes black for no aparent reason, just for a second every now and again, no Jailbreak, software is up to date.
Happens witth the iOS 6 and the one before, not shure about previous iOS versions.
It´s not the Cable, Wifi or Lan.Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Reset the Apple TV (Settings > General > Reset > Reset all settings)
Restore the Apple TV (Settings > General > Reset > Restore) -
Why does my Ipad 2 keep going black ahd back to the apple logo. It eventually goes to the home screen and allows me to try something else but after about 30 seconds it happens again. I have already rebooted several times?
Make Sure iOS is updated to the latest version
Reboot the device by pressing and holding down the home and sleep/wake buttons (power) at the same time until the apple logo appears on the screen, then let go.
If that doesn't work then reset the device by going to settings/general/reset/reset all settings -
Goes black and when you tilt it comes back on.
Macbook model A1342 goes black and when you tilt it comes back on. Is there a fix?
If your Mac is off then start up. As soon as you hear the boot chime, hold down the Option key until the Mac and Windows Disks show up. Then click on the Mac disk and the arrow below it. After it boots up in Mac then go to System Preferences>Startup Disk and select your Mac partition as the Startup disk.
If you are in Windows then look for the Boot Camp icon on the taskbar. It will look like a gray box sitting on one corner. One of the options when you click it is to restart in Mac OS. After it boots up in Mac then go to System Preferences>Startup Disk and select your Mac partition as the Startup disk. -
My iPod has a white screen. After holding down the middle and menu button, the screen goes black then back to white and beeps twice. I have returned to original settings and resorted content to no avail. I still have a white screen. I have plugged it up and tried resetting again and again, still a white screen with two beeps - help.
I have the same exact issue. Fifth generation iPod Nano, blank screen, Restore had no effect. I'm running Windows 7 Home, with all software up-to-date. I suspect hardware damage. Any clarification would be appreciated. Thank you in advance.

New (3mo) macbook air screen goes black and sometimes won't come back on after I unplug it from the power cord. Any ideas why it is doing this? Sometimes I have to hold power button for 10 seconds for it to shut off then back on. Sometimes holding the power button for a second is enough for it to come back on.
I took it to the Genius Bar, and they identified it as a hardware issue. Just got it back today. Parts replaced were:
620-5629 Display Module — Symptom: Distored/blurred/focus video issue
605-3284 Top Case with Keyboard — Symptom: specific key(s) do not work
So far so good. I'd suggest taking it in and not trying to work around it — it's a rare hardware issue (given the number of threads about it) and should be replaced. -

Screen keeps going black and I can't get it to light back up
I just purchased a "pinkberry" and am getting very frustrated with it. It keeps going black and no matter what buttons I push I cannot get it to light back up. I got it yesterday and charged it for about 12 hours so I know it's not that the battery is low.
seems like a hardware problem. Return the device to where you bought it and claim a new one.

My iphone 3gs keeps going black and to a "thinking" icon
my iphone 3gs keeps going black and to a "thinking" icon and will do this for a long time and won't stop till I do a forced shut down. It's all sporatic as to when it does this. Plus it's adding pictures to contacts that don't normally have pictures and taking them away from ones who do have them. Does anyone have any suggestions? I have iOS 5.1.1 on it still b/c my iTunes won't download the newest verision of the iOS (yes I have the most recent iTunes on my laptop, yes I've tried multiple different times to download too) but I've heard others say not to put the newest iOS on the 3gs b/c it locks them up.
Try doing a reset on your iPhone,
Reset your iPhone by pressing the 'Sleep' and 'Home' button at the same time for about 15 seconds or so. Your iPhone will then go through a reset / reboot procedure and will be ready for use within about a minute.
Don't worry about doing this as you will not lose data or settings.
Good luck and do report back. -
Picture going black with LiveMotion
Hi, I have 6 web cameras (4 Creative Live Motion and 2 Phillips). I prefer the LiveMotion due to Pan/tilt but also have 2 Phillips due to high light sensivity of only 1 lux.
My problem is that it seems to occur some kind of problem with the LiveMotion webcam driver. I am running 5 webcams 24/7 in my vacation home and it is quite annoying when the picture goes black on the LiveMotion cameras. It is several weeks (sometimes moths) between each time I visit my vacation home so I do not have the opportunity to disconnect and connect the camera (USB-plug) to reinstall the drivers.
This have happened once on three of the LiveMotion connected PCs and twice (now for the second time) on one of the PC/webcams. I have noticed that on old/slow computers the image may go black but is possible to retrieve again by reducing the image resolution/size, frame rate etc. However all these LiveMotion cameras is connected to Pentium 4 PC's with Windows XP pro SP2 and a minimum of 1 GB RAM. 2 of the PC's do however not have USB2, only USB1/1.1
Visiting my vacation home I was able to disconnect the webcams and reinstall the driver and got back a correct image (not black) and the mentioned 3 LiveMotion Webcams and PCs. Now (6 moth later) for the second time the image from one of the webcams has gone BLACK ...and I am not able to fix it by reducing image size, frame rate etc nor can I reinstall the webcam driver since I can not disconnect and reconnect the webcam cable.
Any suggestions on what to do/try to fix this problem remotely (over winXP RDP)?That shouldn't happen. Reboot and hold down the option key. Choose the Lion Restore Disk to boot from. Select Disk Utilities from the menu and run Repair Disk.

PlayBook lags and then the screen goes black and does not respond
Hello guys,
As the Subject line summarizes, my tablet was working like charm since the date of purchase, back then in April last year. However, on these days it has been performing weird. It has always been fast and smooth, but since last week it has been lagging and not no responsive to the touch.
To tell you gusy fast and clear, it boots up as normal, fast and smooth, apps open and close as usual. Then it starts to lag, and freezes for one second, responds and freezes again but this time will not respond again and finally the screen goes black and stucks there until I make a hard reset and it reboots normally, until it does it again, and again.
Relevant information:
16GB model, 1.5GB free storage available, sideloaded a few android apps today, recorded a few videos
the device manager software on the pc makes no difference, as the PB will anyway freeze and go all black even if it's backing up or something.
HELP?Make sure any important data is backed up preferably by drag and drop to a pc.
When it is working properly, try gently squeezing the playbook between finger and tbumb around the black bezel border. Especially either side of the lower sockets. If it goes black it's probably a bad battery or screen contact.
1.5 GB is not much spare storage, by the way. I would never fill more than 75%.
