Encore WT8-A starts to turn on but then the screen goes black!?
This began nearly a week ago, I had just installed a few apps and my battery died. When I tried to turn the tablet back on it showed a dark blue or even greyish screen. I waited over night and tried turning it out again...this time it began to start, showing the Toshiba start up screen, but then the screen went black.
I have tried to hold the power button, does not work. It will only partially work while on the charger, nothing happens unless it is plugged in.
I did do a Google search and found out that this could be a Bitlocker problem so I tried once again after waiting a few days, I was able to get to a screen allowing me o input a recovery key. The recovery key worked and then I was sent to a page saying that my PC started wrong, restart. When I allow it to do so the process starts all over again...
This tablet is only about 6 months old and I just started using it regularly a few months ago. It hasn't been damaged and I am certain there is no virus because I have software that I run weekly. I am clueless as to what to do to make this work. Has anyone else experienced this problem, if so how was it resolved?
It seems that a few months ago Toshiba started shipping devices with Bitlocker enabled (one I bought a year ago did not have, one I bought in November did. I turned it off and decrypted the drive immediately.This seems to be an industry problem and not just Toshiba. "Someone" made a firmware revision that turned it back on since other Tablets have reported the same problem.
I have seen reports of three stages of Bitlocker:
1) Not encrypted - no key
2) Encrypted using a personal key (may be stored in your Microsoft account and recovered from there - is about 25 digits)
3) Encrypted but Bitlocker turned off. Key stored on hard drive and "decrypted on the fly". I suspect this is the problem and happens if Bitlocker is turned off but the drive is not decrypted (takes several minutes). If something happens to "lose" the key then there is a problem. I suspect the key is stored in the firmware (BIOS) and an update may wipe it..
What I would do for any tab is two things:
1) Open diskmgmt.msc and see if any drive mentions Bitlocker
2) Go to "Search" and enter "drive encryption". See what it says
If either mentions Bitlocker or "drive is encrypted" then I would go to Control Panel>Security>Bitlocker and decrypt the drive (not just turn off). If you need disk encryption then make sure you keep a copy of the key offline.
If that does not work or it is locked already then a full recovery with reformat may be needed.

just bought a new iphone4 and was loading os6 and now it won't turn on. the apple glows like it is starting up, then the screen goes black and then repeats the same process over and over. i have tried to reboot multiple times now
I am assuming the phone was working prior to you installing IOS 6? Did you use itunes to install IOS 6 or just run from the phone?
When I tried to do the Over The Air update to IOS6 on my iPhone 4, it errored out and I had to connect it to iTunes and select "Restore" from the summary screen after iTunes finds the phone is connected. If this works for you, it will go through a couple of reboots that take a few minutes to complete. It should then give you the option to start with a fresh new phone or to use one of your previous backups to load your contacts and other information, provided you have backed up the phone previously.
I hope this helps you my friend! -
I tried replacing the screen with no luck. The same thing happened with the new screen. I replaced the backlight coil and the backlight ic and still have the issue. I don't know what else could be the problem. If the battery is completely dead and I plug it in the "charging battery" symbol shows just fine during the entire time it is charging, but as soon as it starts to boot up the apple logo shows for a split second then the screen goes black. The rest of the phone still boots up just fine. I can use SIRI, press the lock button like I'm about to use my phone and slide my thumb across where the "slide to unlock" would normally be and it will make the unlock noise just no picture display. I am pretty tech savvy when it comes to repairs and all of the connections look fine, replaced backlight coil and ic, replaced LCD/digitizer, tried a restore, tried a DFU restore, multiple hard resets, but I am at a loss as to where to go from here. I had dropped the phone and put a minor crack in the screen but the phone worked just fine for a couple months after before this started to happen. The phone is still under apple warranty but apple won't cover it because Apple is stating that it is "caused by the crack in the screen." But being a repair technician I know that is not the case... Good one apple. So I took it upon myself to try to determine the REAL problem. Anyone with a little more knowledge have any ideas? Any suggestions are appreciated!!
Yes, I understand that. But The screen issue is not a result of user damage. The phone was not dropped when the screen got cracked. My daughter was standing in a chair at the table and dropped one of her toys onto the bottom of the phone and cracked it right by the home button. (Nowhere near the LCD/digitizer flex cables, connections, or logic board components) then a few months later my phone had died, I plugged it in, it showed it was charging, then Apple logo disappeared and screen didn't work. AFTER contacting Apple about the issue and them telling me that it "is a result of the very minimal crack to the sheet of glass that has no relation to the LCD or Digitizer and that the warranty does not cover it I had taken it upon myself to change the LCD/digitizer to no avail, as well as backlight ic and backlight coil to no avail. But how do I go about letting Apple know that it is in fact NOT due to the cracked screen nor is it due to the flex cable connections? I can't. So the lady that works the call center phones trying to "convince" me that she knows what she is talking about and "convince" me that it is from the cracked screen I have to take her word because I can't show Apple that its not because of that without paying them $199 to fix the screen in which case they will just send me a new phone rather than fix the faulty hardware under warranty.

I tried updating my iPod touch to the newest update. But my iPod was unable to complete the update. Now my iPod doesn't turn on completely. The apple logo appears but then the screen goes blank. I've tried charging it, letting it discharge, I've tried things I found on the internet but nothing seems to be working. What can I do?
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 a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then goes black. The sleep light pulses. From there, I can't turn it off normally. I have tried restarting the PMU. And I have tried unplugging the ac adaptor and removing the battery. From there I have plugged only the ac adaptor in, and it will begin to start but do the same thing once it shows the blue screen.
I tried only using the battery (without plugging in the ac adaptor) and the same thing happens. I tried starting the computer while holding down CTRL, Option, P, and R, waiting to hear the start up chimes 3 times, and then holding Shift as it starts up. But I still get the black screen once I see the blue one, and the computer's sleep light pulses.
I need something very important from this computer. And was able to start it last night. I did not shut down the computer, and was going to take it to a friends to use his printer today. The computer was in sleep mode in the morning.
Thanks for any help!
GinaWhat your describing could be a logic board or memory issue.
You did or did not hear 3 startup chimes? If you hear 3 chimes when you start it, that would indicate a memory problem. Try reseating the memory to see if that makes a difference. If you have 2 RAM cards, try one then the other in each slot. If you have 1 RAM card, move it to the other slot. Powerbooks can develop one bad slot.
You may need to pull the hard drive out of the Powerbook, put it into an external case, then read it from another mac. -
Boots to black in OS X mode (I believe 10.10.2? tough to check right now). I can boot into Windows 8 using Boot Camp without incident. I have booted to Disk Utility and run Disk and Permissions Repair. I have booted into Diagnostics, and no issues were found (ADP000 was the Reference Code given). I reset the PRAM, which gave a louder chime than I had been getting when failing to start up OS X, but otherwise no change. Feeling that my options were exhausted, I attempted to restore from Time Capsule, and it won't connect to Time Capsule, despite Time Capsule being the active router whose network I am connected to. Please advise.
(This is my girlfriend's computer, she tells me that she selected an option to perform an automatic update later, that night.)Install or Reinstall OS X from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
This should install the version of OS X that you had installed.
Be sure you only work on the OS X volume, not your Windows volume. I cannot tell you if you will still be able to boot the Windows volume after the above. You will need to find a fix for that. -

I was having some problems with my mac, safari and itunes was freezing alot. I have to force shutdown and when I tried to start up again i get to the login page, type in my password and it starts to load, but then the screen turns blue for a few seconds and it goes back to the log in screen. What should I do?
Please Help!!Somewhat similar problem:
Put in the password, hit enter, the screen goes blue for half a second, then goes back to login screen and carries on logging in as usual. Drives me mad. It doesn't happen with a fresh Lion installation, nor if booted into safe mode. On the machine in question it also happens to new user accounts.
I've removed all login items, including Startup Items and Launch Demons (pun intended) and Agents, I've compared system login plists with a fresh Lion installation - can't see differences. I've removed Little Snitch and PeerGuardian (no more third party kexts).
@Carolyn: I've done disk maintenance with DiskUtility and fsck and even DiskWarrior, cleaned caches, etc. etc.
Any ideas would be gratefully received.
Sorry for trying to hijack the thread (as it's not about Lion), but it seemed dead anyway. -
When I get to the login page on my macbook, I type in my password and it starts to load, but then the screen turns blue and it goes back to the login.
Iv tryed this numerious times still keeps going back to pasword. Can not get any further. Tried restart holding shift key.. still nothing. What do i do?Thank you for your help.
I couldnt get to the hard drive/ desktop. Soft login not even working. So i could not do any of that.
In the end i took it to Apple and its actually the hard drive on its way out. A common issue with that series of Mac. Funny seeing i dont use this mac much. However being 2.5 years old and out of warrently, Apple have recognise this issue with this series/ Model and installing a new hard drive at no cost.
Very luck and greatful. And not feeling so dumb that it was something i did or could troubleshoot myself.
Hope this helps others that it just might be your hard drive failing. -
Just updated my Ipad operating system and one of my apps starts but then the screen turns white, with only the advertisment at the top showing
The normal suggestions.
Close the app,off fully. Double tap the home screen then touch and hold any of the icons on the task bar until they jiggle, then close them all off by touching the - sign.
Then reboot the pad and try the spp again. If same issue, delete the app, then reload it. ( no charge). You may just have a bad copy. If continues, write to the developer, they may need to do an update. I have an older version of the same app and it works fine.
Since yours is the ad supported version, they are maing real sure you see the ad. Is it as simple as you need to click thru the ad to get to the game? -
While browsing the internet with my iPhone 4S the screen goes black and it looks like it's turning off, but it pops up to the unlock keypad screen. It has plenty battery and I was wondering if it is an issue of using too much of the iPhones RAM or not. I have no other apps open besides Messages. I am getting kind of worried as it started around two weeks ago and it has gotten increasingly frequent.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.

The screen on my macbook has malfunction. When I change the brightness to zero and return to the first level of brightness it works briefly but then the screen starts to flicker brightness and quickly extinguished. It seems to be a bad contact, it would not be normal for a quality product that should have, he has less than two years of use. Not because of the bad use or crash. Someone with the same problem or can help me? It's really a contact problem? I've done all the procedures recommended by the online support. Thanks.
Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

Looking for non-video Photoshop CC Tutorials
Can anyone suggest a tutorial for Photoshop CC that isnt a video? I'm new to the program and I just don't work well with video tutorials. I was wondering if buying the book for CS6 might be useful, or if it would just be pointless. Thanks! Dani Messa
