P2412H - displayed briefly and then the screen turns white.
Hello
I got a pair of monitors of P2412H little more 3 years, bought from a dealer - I don't have tags and monitors say manufactured in September 2011 (so I think that, apart from any warranty).
This morning one of them has failed - it displays briefly, then the screen turns white.
Manual test:
1 unplugged every wire and power button which is held for 15 seconds.
2 reconnect the power cord.
-Switch will blue
-L' initial Dell boot screen is displayed on the screen for less than a second.
-L the screen turns white.
-Stays blue power button
3. press one of the control buttons
-Nothing happens
4. disconnect the monitor
5. connect the monitor to on PC with Windows connected using DVI.
6. connect the power cord
-Switch will blue
-L' initial Dell boot screen is displayed on the screen for less than a second.
-L the screen turns white.
-Stays blue power button
I also tried to reset the monitor according to the instructions of the manual by pressing keys 1 and 4, but as the monitor does not appear, I couldn't see anything.
The monitor did briefly revived properly after one of my attempts back manually, but the after turning on and the new to check if the problem itself had set the monitor returned to the not displaying no not again.
Can anyone help or point me in the right direction on how to fix it?
Thank you
* UPDATE *.
Disassembled the monitor I've used this as a guide to youtube to open the monitor the safely:
cs_setInnerHtml ('video_aebd897a-01ed-42eb-a8c5-b3b6ecee6556', ");
Inspect the circuits printed for all the obvious problems such as cracked soldering or fried capacitors.
Could not see the obvious problems... you realign a couple of back vertical capacitors where some of them were in sharp corners appeared to be very close together as a result.
Back together carefully.
Backwards and now it works very well for 48 hours.

My computer was las night. I turned it on this morning and it says the auto repair or please wait a few seconds then screen goes black or white. It doesn't let me do anything else. It is located on a white screen. Help, please
Hello
Here's the follow up:
-You cannot restore your files once the HARD drive goes 'bad '. You can try to start the computer by using a few Linux based Live rescue CD, but chances are very small
-You can not restore factory default before replacing the HARD drive as the old is defective. You must insert a new and then restore because the information is indeed stored on the HARD drive (new)
-If you know how and where you can event the same HDD - manufacturer 678312-002
If this is not the case, just use some as suggested above and as explained in the guide Service and Maitanance.

Follow these methods.
Method 1: Scan the file system (CFS) auditor to repair corrupted files.

Netbooks and also most computers these days, do not come with an installation CD. Instead, it has a recovery partition. Assuming that you have not deleted the recovery partition,

Start my computer, it will default to the CTRL ALT DEL screen. After graduating in the login screen I enter the password. Windows will start and then the screen starts flashing and the screen say Logging Off, then restore the screen to the CTRL ALT DEL I can boot into safe mode. All other functions will not work.
Thank you
I guess you wanted to ask how to solve the problem. If then all in Safe Mode you can use system restore to set up Windows to a point when the problem did not exist.
