Screen flashes off and on - ideapad flex 10

Hi all,
Hoping for some help from the experts! My ideapad flex 10 has over the last month starting flashing off and on randoming during use. The screen is still there just cant see it. Also mouse seems to work but becomes impossible to use as flashes nonestop until you manage to restart it. Flashes quickly and seems to black completely but helps when i shake the mouse to get the screen for a second or so.
Any help would be gratefully received!

Sigh Is it possible that I am the only one seeing this?

If you keep getting a 'red' message it means that the HDD is faulty and will have to be replaced. You will have to format the new HDD in Disk Utility>Erase and then install the OSX and your data from Time Machine.

Websites I've loaded onto my home screen won't delete. I press the icons. Wobbles then freezes and homescreen uploads flash off and on (apps too but I can delete them from manage storage)

Websites I've loaded onto my home screen using the + to home screen option won't delete. I press the icons. Wobbles then freezes and homescreen uploads flash off and on (apps too but I can delete them from manage storage)
i need to reboot to stop it and I'm stuck with loads of homescreen icons on my iPad

You're welcome. Glad to hear you got it sorted out. If you like using website icons you can bookmark them as Favorites and they'll be on your Safari page instead of your homescreen and they're much easier to get rid of. Also you could turn on Favorites bar by going to settings> Safari> show Favorites bar> on. See screenshot.

Refurbished iPod touch 3rd gen won't start. Just got it today to replace my broken one. It freezes at the screen with the apple logo, then flashes off and tries to restart again. Help,

I have tried holding the power home button but all that does is turn it off. When I try to start it again it goes into the same loop.

MB screen flashes on and off...HELP!

Just got a new macbook for my wife. Came from Apple with 2 sticks of 256mb RAM. I added 2 1gb Patriot sticks from Newegg. all seemed well. but now under load, not full load just opening apps, the screen flashes black and then after a few seconds it comes back on. It happens often enough to be annoying.
Here's what I did:
1. Replaced with apple shipped ram.- Doesn't seem to occur, so I figured bad ram...
2. Ran memtest on both stick individually. 3 passes on each stick
3. Reset PMU as advised by AppleCare
Still could be bad ram but...
1. I pulled the two 1gb APPLE RAM sticks from my 17" MBP, still occured.
2. Tried the Patriot 1gb sticks in my MPB, all is fine.
So I don't think it is bad ram?
Any helpers out there? Apple wants to blame 3rd party RAM, but their ram that shipped with my MBP exhibit's the problem too...

My screen was flashing just like yours and failed tonight, 20 days into the purchase. Take it back and get a refund. Don't take another macbook until they get all of these quality control issues worked out. This was my third macbook and I had not been having any problems, but was experiencing the flash. It is starting up in the background and can be used in target disk mode, so the issue is the screen. Return while you can, it will eventually go out completely.

Hard Drive icon won't open and menu bar flashes off and on

All of a sudden, in the middle of the day, my eMac went haywire. I can launch apps and docs are one the desktop. But I cannot open the Hard Drive icon. If I double-click on it (or used Command-O from keyboard), the icon won't open. And when I attempt to open it, the Finder Menu Bar begins flashing off and on (vanishing, reappearing, vanishing) across the top of the screen. I haver rebooted, run disk utility to repair permissions, even booted from TechTools to run its diagnostics. But still no access to the Hard Drive icon. I logged out and logged in as a TEST user, and same thing happens even when logged in that way. Literally, this happened in an instant. One minute the eMac was fine, then this started. Anyone else seen this? -- david

If the problem exists in both your regular account and your Test account odds are that it is at the system level. You can try a Safe boot (hold down the shift key at startup) to see if there is a third party startup item or one of the optional Apple functions that is causing the problem. You could also boot from the installer disk and use the Disk Utility->Repair Disk function. If you have a utility such as Tiger Cache Cleaner which will do a deep cache clean you can also try that.

HT1481 Ipod nano flashes off and on and will not reset.

This has been such a mess. This was a Christmas present and I can't get it to work. How do I get this to work?!!! This is my first Apple product and I am not happy. The Ipod nano just flashes off and on. I have downloaded itunes but nothing has happened; it just flashes off and on with the Apple symbol on the screen. How do I fix this?!!

Hello janicon,
Thank you for the details of the issue you are experiencing with your iPod nano. I would be concerned and frustrated with this as well.
I recommend following the steps in the section titled "Will not turn on or screen remains dark" and "Screen is unresponsive and displays Apple logo or white screen" in the following article. If you are also not seeing your iPod in iTunes when your have your iPod connected, I recommend the section titled "iPod not recognized by iTunes or computer."

My ipod touch 4th generation has frozen whilst being turned back on. The apple logo has been on the screen and ever so often the screen flashes white and then black. How do I get it to unfreeze at this stage?

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.

I have an iPad 2 and all of a sudden I have no sound in game apps. I have usual volume in videos and YouTube, I do get volume for games if I plug in headphones. I have switched to screen lock off and on again and I have also done a reset twice.....help :)

I have an ipad2 and all of a sudden I have stopped getting sound in my game apps. I get normal sound on YouTube and I player and downloaded DVDs. If I plug headphones in then I can get sounds for the games. I have switched the lock screen button off and on again and done a reset twice, can anyone help me with this?

Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

Monitor is flashing off and on

I just started up my computer this morning and my monitor (30"cinema) was flashing off and on. I have my Cinema preference setting to "turn the display on and off". I managed to keep it on long enough to change to "does nothing" so it stays on, but I really need that functionality for rendering overnight and not leaving the display on.
I checked the button and nothing is blocking it. Could it really just burn out if I never actually use it more than maybe 10 times? Is there anything I can do to troubleshoot this?
thanks,
Dave

Sometimes just unplugging the display from power and the computer for a few minutes will fix things.

Why are my icons flashing off and on?

My I icons flash off and come back is about a second. This repeats about every minute as if it is stuck in a loop.

Well, I too had a case of the "flashing icons" beginning a week after downloading Maverick. Flashed about every 1-2 minutes. I asked Mac support about this through a "chat" and received about 2 pages of tutorial info from them that was so loaded with "geek speak" and tech terms, I was about to throw myself over the railing of my 2 story apartment. At 63, there was no way I could follow this "stuff" without probably destroying my MAC and tearing out what little hair I have left.
None of it mentioned playing with Google by the way.
One option was simple however: Re-download Maverick and see if that does it. Frankly, I like the practical ideas. So I went back to the App Store and re-downloaded Maverick last night, and all is fine. No sluggishness, not that I had any to begin with, no loss of data, no nothin'! Just smooth sailing. Give it a try.....there's nothing to lose.
