Screen flashes then locks

My screen on a mac pro 15 in 2.2g core 2 suddenly started to flash on off repeatedly. I had to hard crash the computer to get it out of that screen, but now it locks up just after the "bong" in the startup apple screen. Any resolutions? I am up to date within a week on software.

Try rebooting while pressing "d"
With any luck you will be taken to a blue screen with white writing, and you will be able to run a diagnostic test. Run this, and this will let you know if you have any hardware issues.

I recently dropped my ipod in water and i placed it into rice for 3 days. Then when i try and connect it to the computer it shows the no battery screen with just the lightning bolt. and when i try to restore it the screen flashes then resest

Then when i try and connect it to the computer it shows the no battery screen with just the lightning bolt. and when i try to restore it the screen flashes then resest to the no battery screen and i get error 1602. Do you know what is wrong with it? do you think its just the battery cause i can replace that for cheap or do you think the circuts are fried?

No. It sounds like the water destroyed the component inside the iPod.
About your only choice now it to take it to Apple and pay for a replacement.

Screen flashing then faulty

The screen started flashing then keys went intermittent. Needs hard press to work. Any deals?

Could use a little more info here as I'm really not understanding the problem.
Make sure IOS is updated to latest version
(How to update your iOS device
http://support.apple.com/kb/HT4623)
Reboot device by pressing both the home button and sleep/wake (power) buttons at the same time for 10-15 seconds 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 (or for network connection issues 'reset network settings').
(no media or data will be deleted from the device, this will only take a minute).
If that doesn't work then backup and then restore the device as new first (to isolate cause of the issue). Then from backup if necessary.

Pavilion dv6-3040sa, black screen, flashing caps lock

Hey all, In need of some help for a friend, her laptop has had this issue for a while now and only just come to me for help. Her HP Pavilion DV6-3040SA has an odd issue with it, if you power it up the display doesn't come on and the caps lock just flashes, it will continue to flash until the laptop is turned off. On the help section a flashing caps lock does not refer to any particular error. I've reseated RAM, tried hard resetting, reseated the CPU and it managed to power up, then after it was turned off, it wouldn't power up again and had the same issue, after playing with it some more it powered up and worked for 2 days, when it promptly stopped working again. Any reason for this issue?

Processor failures can be have inconsistently. I have seen processor failures start with 1-2 second hangs in the OS to working one day and not at all the next.
The blinking code you have desribed is a beep code of one. Review the following table found here.

The options for a blink code of 1 is to reseat the CPU as you have already done or to replace the processor. Since the issue returns after reseating the CPU, it looks like the CPU needs to be replaced. Sorry.

Screen flashes then computer locks up.

When using battery power sometimes my MBP screen will flash several times. When that happens the track pad will still allow the movement of pointer but I can't do anything. Can't close apps, windows, access apple icon etc.. Have to reboot to correct. I have not seen the issue wihen the power cord is connected. When it has happened the batter power level has been somewhere between 11 & 33 percent.

I forgot to mention that I have already repaired permissions a couple of time.

Ipod nano screen fade then locks

has anyone had this problem where if you hold the menu button down, then the 2gb black ipod nano locks up and the image on the screen fades away slowly until the lcd is blank? then the nano won't start up anymore (until it is plugged into a computer). toggling hold does not work, and pressing both the menu and center button doesn't do anything either. is this a defect for my particular nano or is this possible some kind of software bug that needs some kind of restoring?
also, on a related note, plugging it in to the computer (xp) sometimes brings up the apple logo then it jumps to a discharged battery lightning logo (battery is full). i have to keep plugging/unplugging until i get to the "do not disconnect" screen, then the nano works fine and shows the full battery on the upper right (to prove its charged).
any help on this would be great, thanks!

I figured out the cause of this problem, basically if you reset your ipod (menu and center), then the nano freezes and the screen image fades... has anyone had this problem? I'm also having a very very difficult time trying to get the nano back to a working state since none of the buttons work... when i plug it in to the computer, the screen shows an apple, backlight flashes on for a second then goes away, and it quickly jumps to a lightning bolt battery... unfortunately the battery is fully charged (green) from before the nano froze, and constantly plugging/unplugging the usb connector sometimes brings the nano back to normal working condition...
I was wondering, what happens on a normal nano when you reset it (menu and center) without being plugged in... does it freeze as well?
I also tried a full restore via ipod updater when i finally got it working, but the problem still exists and i hit menu+center and froze it and now i am plugging/unplugging to the computer to try to get that 1% chance it will boot up properly... any advice?

Laptop Black screen flashing Caps Lock

Hello. I have a HP ENVY 17-j130ea which i purchased a couple of weeks ago and decided to put a mSATA SSD in there for the cache drive.
I installed the mSATA drive, but when i put it back together i forgot to put the HDD in.
When I turned it on it came up with a message saying there was no OS installed then the screen went blank.
Now when i try to turn it on with or without the mSATA or HDD in, the screen stays blank and the caps lock blinks twice every three seconds.
I have tried leaving it for 5 minutes, I have unplugged it, taken the battery out and held the power button down for 1 minute, I have made a bios recovery key and turned it on with the 'Windows' and 'B' button held down and it does the exact same thing every time.
TLDR; I put a mSATA drive in my laptop and it is giving me a BIOS error and no matter what I do, I am unable to fix it.

I have a little more to add
If I turn it on normally, nothing happens on the memory stick (no lights or anything)
If I turn it on while holding down Windows and B, the memory stick turns on after about 15-20 seconds, the light flashes for about 5 seconds then it stops flashing, it just sits on a solid light.
Its almost as if it is searching the memory stick for the files but fails to find them.
I used sp65000.exe to create the recovery stick

10.7.3 Screen flashes then shutdown...And KP's

2010 i5 MBP with 8GB Crucial ram....In January I began getting random shut-downs...The screen would go garbled, then flash 2-3 times, then the computer would shut down...Has happened somewhat infrequently until this week...Happened 4 times on Tuesday and 3 times today...
I've been reading about the black screen issues on these models running Lion, but I havent seen anyone else complain of the screen going nuts then instant shut-down...While searching I found the support topic on Kernel Panic...I've never had a KP occur, but while actually reading about KP on the support page, it happened. I removed and reseated the RAM,and was ok for 2 days...But then today Ive crashed multiple times and had another KP. Im currently running memtest, which so far says RAM is ok...My next step is to do a hardware test, but I dont have my access to my install disks until tomorrow...The flash and crash occurs at random times and in random apps, but the KP's have occured when Safari was the only app open....
Im wondering if this crashing is a hardware problem related to the graphics? Im currently running wth graphics switching disabled to see if the problem occurs again. What other steps can I take to eliminate possible causes? If there a way, other than disabling graphics switching, to narrow down a cause to the Intel graphics or the logic board?

Completed the hardware test this AM, and it reported no problems...I have no beeps during boot...It did beep upon the first KP...It was a series of 3 beeps, but it was unexpected, and I cant tell your if it was just 3 repeating beeps, or if it was the SOS code...It hasnt beeped since that first KP...Ive looked through Console and found the logs...Most of it is Chinese to me, cant really tell much from them.....At this point I guess Im another victim of the graphics switching driver crash problem...Hopefully Mountain Lion fixes this, if theres no update sooner...

Screen flashes then goes blank - S2012 13" Air

When I start up my new Air, the screen will sometimes flash bright white/gray then go completely blank as if it fell asleep. The keyboard lights are still on at this point. This will happen after several restarts. Is there a software fix, or is a Genius visit in my near future?

T400 screen flashes then goes black

As the thread title says, my lenovo t400's screen recently started flashing. It wasn't that bad at first but it increased in frequency and started to be very annoying. I noticed changing from battery to cable would temporarily stop it, also turning down the brightness helped.
However the problem started getting worse and now when I am forced to have it on the lowest brightness settings. If I turn it up it starts flashing erratic and then the screen turns off. The system itself keeps working though and if I turn the laptop off or in sleep mode and then turn it on again the screen "works" again (still with flashing). Ofcourse if I left the brightness above its lowest level it will instantly go black again.
Also most likely related, half of the screen (left side) has taken on an "redish" collor.
What could be the problem and is it something I can fix myself?

Correct, these are the original specs of the machine:

I can think of three possibleculprits, LCD cable defective, inverter defective or LCD panel's backlight defective. The cable and the inverter will be cheaper to replace, the panel will be more pricey I guess, (I don't know the current LCD panel prices).
T400's came with standard CCFL and LED screens. You need to find out which one you have. You can try the part lookups page from Lenovo and follow the instructions here: http://support.lenovo.com/en_CH/product-and-parts/partsLookup.page?
(You need the machine type and your serial number, please don't post the serial number here in the forum)
P.S.: If you have a LED screen cluprits could be the cable or the panel, no inverters there AFAIK)

Ipod screen flashes then goes blank

My iPod initially flashes, when turning on. You can see the time, or the apple, but it then goes blank. I don't believe the LCD screen is shot, or it wouldn't flash. How do I fix it?

HDX16T LCD Screen flashes then blacks out, quick to sleep and out brings it back...

I have an HP HDX16T-1200 CTO with the 1080 edgeless disply. All of a sudden the screen has been doing weird things. While it is working fine, it will start to flicker or flash a little. Sometimes that just goes away, and sometimes the screen then blacks out. To get the screen back, I have to close the lid (put the computer in sleep mode), then open it again. Sometimes it is fixed for hours, or a day... and sometimes it is fixed for 3 minutes. Please advise, thanks!

If you can clean and/or put new thermal paste on the chip itself that may fix the problem. If you search the web for "*ERROR* Timeout setting UVD clocks!" you'll find many threads on Bugzilla about this issue. It seems that this is a long-standing issue (dating back to 2013 I believe).
So are you saying the GPU is overheating? This is the card I am using: http://www.newegg.com/Product/Product.a … 6814150605 I have it hooked up to my motherboard on my desktop. Would this be related to something switching between the motherboard graphics and this card?

Blue screen flash then no screen

During start up. I get a blue screen for about a second then it goes away. I can adjust the brightness and can kinda see something. Please help!

You must repair the HD, if Disk Utility or fsck should fail to repair it, your best bet is DiskWarrior from Alsoft, you'll need the CD to boot from if you don't have another boot drive...

Screen flashes then MBP shuts down.

From time to time I get a flashing display then the computer shuts down.
Pressing the power button then restarts and it returns to where it left off.
MBP 13" Retina - December 2014.

Hello iansp,
Thanks for using Apple Support Communities.
From your post I understand that your Mac will spontaneously flash the display and then it will shut down. This indicates there is a kernel panic occuring on the Mac, causing the computer to shut down. To be honest, troubleshooting a kernel panic can be a tedious and difficult process, so you might want to consider making an appointment at your closest Apple Retail Store, or Apple Authorized Service provider for support. If you'd like to look at how to troubleshoot a kernel panic, take a look at the link below.
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support
Take care,

I click on firefox update for Mac OS X 10.6, the screen flashes then nothing happens. Pease help

There is really nothing else to add, I have tried to download the latest vesion via the email sent to me and going onto the Mozilla web site.

In addition to Stedman's spot-on reply --
When you buy an upgrade disk, all updates in that OS can be found on Software Update.
For instance, I bought Snow Leopard at 10.6.
All other updates have been free and downloadable. So I'm not a 10.6.7.
10.4 (Tiger) went to 10.4.11.
10.5 (Leopard) went to 1.5.8
10.6(Snow Leopard) is currently at 10.6.7.
Now, when Lion come out (the next major upgrade of OSX), I will have to pay to go to 10.7.
After that, updates are free til 10.8 comes out.
