T400 screen flashes white once, won't start

Whether I try turning it on with battery or AC, the same issue occurs. The indicator lights turn on but the screen flashes white and doesn't display a thing afterword. Something is definately broken, but what?

You should methodically follow all the steps in Apple's article on Gray screen appears during startup.
Good luck.

IPhone screen flashing white/black/blue

I have a 64GB iPhone 6 Plus, the phone is running the most recent version of iOS 8.
I didn't drop the phone, get it wet or anything. All of sudden the screen started flashing black and white, and blue. I can still send receive texts, calls etc, sound is working fine. I just can't interact with the screen because it's flashing colors. It is very similar to the problem experienced by the user in this thread: iphone 6 plus screen flashing white and black
I've already rebooted the device and tried plugging it into a computer (it wont recognize the phone because I've never plugged it into the computer before).
I'm on vacation, at a wedding and I don't have access to an Apple Store. Is there ANYTHING I can do to get my phone to working order?

Thanks for that info. I restore the phone without any data In the end (as a new device). In order to make the problem go away I had to:
1. enter DFU
2. Update device
3. Restore device
4. Setup as a new device
It didn't work without completing all 4 of the steps. after setting it up as a new device it still flickered a bunch and the color were funny. Especially when looking at high definition photos. It was like it was threatening to start flashing black and white again. I turned the phone off for a while and then when I turned it back on it was fine. It's been fine since then. well see what hapPens.

Ipod nano 7th: Screen flashes white (turns off) and stops the music.

I just got a brand new Ipod nano 7th: Less than 10 seconds after the song starts playing the screen flashes white, the apple logo shows up and it returns to 'home' screen. Battery is full. Tried to restart but that didnt help!
What could be the problem?

Hi joannefromhkg,
If your iPod nano (7th generation) will not turn on at all I would suggest that you troubleshoot using the steps in this article -
iPod nano (7th generation): Hardware troubleshooting
Specifically -
Follow these steps if your iPod a power-related issue.
Will not turn on or screen remains dark
Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
If iPod does not turn on after ten minutes, try resetting it while it is still connected to power. Reset the iPod by holding down the Sleep/Wake button and the Home button for at least six seconds or until you see the Apple logo appear.
If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
If the screen remains dark and will not turn on, then your iPod may need service.
And -
Issue not resolved
If the issue is still not resolved, please read this information on servicing your iPod.
Thanks for using Apple Support Communities.
Best,
Brett L

My ipod wont charge. The screen flashed white yesterday and now it doesnt work

My ipod wont charge. It died yesterday and when i did the lock home button thing the screen flashed white. After that the dead signal wont even pop up now an suggestion. Its a ipod touch 4 generation, 36gb I tried charging it to my computer, wii,tv, wall plug NOTHING WORKS.!
1. The lock button and home thing WONT WORK.

Try:
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- 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.

View in browser - screen flashes white

Although I'm fairly new to CS5, all has been going well til now. New site, whilst testing in Google Chrome and Safari, when loading between html pages, the screen flashes white. I'm using a couple of jsQuery - one is Galleria, the other is page transitions from onextrapixel.com . Haven't experienced this with any other site I've done. Would appreciate any words of wisdom.
Thanks

Would it be possible to see this page uploaded somewhere?
I'm thinking it has something to do with the combination of the two scripts. For the onextrapixel transition can you provide a link to that one.
And lastly this jumped out at me in your code:
<script type="text/javascript" src="../html/jquery-page-transitions/js/jquery-1.6.4.min.js"></script >
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js"></script>
For some reason you are including 2 different Jqueries. You really shouldn't need this unless one of your scripts is using an older version and if 1.6.4 (the latest version) is working you can keep one or the other, but you don't need both.

My iPod won't turn on and the screen flashes white

the other day while using my ipod it all of a sudden reset and a diagnostics screen appeared and it started running all of these tests after which it stopped working. i then proceeded to plug it into my computer which recognized it and, after disconnecting, worked for about 10 minutes before it kept flashing in between the apple screen and the low battery screen. after a little of that it shut off completely until i plugged it back into my computer. After plugging it back in the screen lit up white and stayed lit until unplugged. once unplugged it flashes white every few seconds and thats it. my computer no longer recognizes it and restarting/reseting does not work. i could use all the help i can get. thanks.

Any help here?

G3 screen flashing white and coulors. Help!

do I need to get a new screen?
Please help as this is my first mac got it just for few months and i love it
Thanx

Hi, Gary. Welcome to Apple Discussions.
It sounds like you may be having logic board problems. Enough Dual USB G3 iBooks suffered from the logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Do the symptoms look familiar? After leaving it sit overnight, does squeezing the case to the left of the trackpad allow you to start up and work for a bit as long as you keep the pressure on it there? If so, you may want to consider trying the shim fix suggested by John Sawyer in the Apple Discussions iBook G3 (Dual USB) Displays Forum:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.
John Sawyer
CJS Macintosh Repair
Instructions for removing the lower case:
iFixit.com
If the shim fix doesn't work (or you're leery of trying it), DT&T Services in Fremont, California offers the cheapest repair I've found. They have a six-month warranty on the repair.
Once you get it fixed, try never to pick it up by the left front corner alone. The theory is that picking it up by the left front corner alone can contribute to logic board failure when the case flexes, causing the graphics chip to come loose from the logic board. If you're picking it up in your left hand (as I often do mine), pick it up in the center under the trackpad.
Good luck.
Please note: As a G3 iBook is quite old at this point, if you are faced with paying a repair bill on it, it may be wiser to put that money toward a new (or used) MacBook. They are quite a spectacular upgrade from the iBook G3. Again, good luck with whatever you decide to do.

How many times should my screen flash white after a restart?

Every time I do a Restart on my 17" MacBook Pro, the screen goes black, then flashes white for a few seconds, and repeats over the next 2 - 3 minutes approx. 4 more times. I am used to seeing this process only once on my previous MacBook Pro's. Is this a common sequence?

Blackberry curve 8530 - startup problem, screen flashes white

Whenever I try to start my phone this is essentially what happens.
I plug my phone into a charger, the red light lights up.
Proceeds into the hourglass, then the screen partly flashes white. and then back to the red light.
This then proceeds to happen forever. Is there a fix? i've tried to update the software through desktop manager but there is always and error when i try this. I use a mac and want to fix this asap.
Thanks

Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
Wait another 2 hours, no matter what the LED or the display does
This has been known to "kick start" some BBs.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain a known good and already fully charged additional battery...use it in your BB and see what happens
Obtain access to a known good and identical BB...use your battery in it and see what happens
The results of this will indicate if it's your BB or your battery that has the problem.
Unfortunately, most of the good "tricks" for recovering a BB work only on PC...not MAC.
Good luck and let us know!
Occam's Razor nearly always applies when troubleshooting technology issues!
If anyone has been helpful to you, please show your appreciation by clicking the button inside of their post. Please click here and read, along with the threads to which it links, for helpful information to guide you as you proceed. I always recommend that you treat your BlackBerry like any other computing device, including using a regular backup schedule...click here for an article with instructions.

White MacBook won't start up.

My MacBook won't start up at all. Before it completely went haywire, it would just freeze and the whole computer would be frozen and . It wouldn't even let you "force quit". Most of this happened when I opened iTunes. Now when I start it, the gray screen comes up, it shows the little apple sign, then goes gray with a circle with a line through it. I tried starting it up with the utility disk and holding down the "C" key, and instead of the circle it has a question mark inside a file sign and flashes. Now I have no idea how to get the disk out and my computer is useless. Please help me.

Hi,
*"question mark inside a file sign and flashes"*
A flashing question mark appears when you start your Mac
Flashing question mark can mean several things. One the drive is failing or failed. Two, it can mean that your Mac can't find a system folder to boot from. Try booting while holding down the Option key which prompts the Startup Manager window. If that doesn't work, it's time to replace the drive.

IMac screen turns white, then won't restart

24" iMac running 10.6.8
Just installed MacKeeper software and did a "Fast Cleanup". It says my system is running "excellent". Then, one day later, I am on the internet and the screen goes white. Pulled the plug as that was the only way I could get it to shut down, restarted, screen is now 50% white (frosted) but I can see the type. As I am talking to MacKeeper on the phone, it goes completely white again. Third time try to restart and button won't even turn it on. Fourth time restart (as above) and have the 50% white screen again. Long enough this time to figure out my Apple ID and password and type in this question.
Do you think this is software related (MacKeeper)? Or is this my first Mac to ever have a real problem.

Didn't get a response here, so I read some other similar posts. I've tried everything: rebooting to safe mode, uninstalling MacKeeper, and running disk utility (which said it could find no problems).
Any other suggestions out there folks?
