Vaio LCD problem


Periods.......Nice little items because they denote the End of a sentence.
See how this works?

"I have a vgn cs36gj, I was working with it, suddenly the LCD became pale black, I connected it to external monitor and it has a picture, sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

Now you try it.........

"I have a vgn cs36gj. I was working with it, suddenly the LCD became pale black.
I connected it to external monitor and it has a picture."

Okay, I got that part.........

"sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

WHICH LCD?
Laptop LCD?
External monitor LCD?
Man on the moon LCD?

1) If the external monitor LCD goes 'pale black', the problem is the graphics chipset.
This I do not believe

2) If the laptop LCD goes pale black, this I believe.

While i am on my computer my hp w1907 monitor goes black. if i shut the monitor off and wait a few minutes it will come back on but then it only stays on for a couple minutes and goes black again.


This sounds like a power board problem. Could be failing power capacitors, which are allowing the charge to leak ( stripping the screen, not recommended) will show bulging or leaking capacitors). Or it could be an issue with the PCB. The fact it will restart once it has "cooled down" points to this.

I'm assuming you have tried the monitor on a different computer, just to eliminate the graphics card (unlikely but worth a go)

Solution..get it checked by a qualified TV repairman, it may a be a simple fix.

Sounds like the computer is shutting it down and the monitor is fine. Check for viruses then check your settings in device manager for the screen saver and power down (screen off) options.

TV picture goes out


The tv is shutting down because of a power problem. It could be the power transformer or a color gun overheating. Expect at least a couple of hundred dollars to fix it. Some shops will do house calls for around $65 and can diagnose the problem and give you an estimate. Usually they can just remove the board, take it to the shop and repair it, then reinstall it.

Monitor


Is there still power to the monitor or is the screen just black? Do you hear any sort of sound when it goes black? Does the time the picture goes out vary or does it happen after say "X" minutes/hours everytime? Do you have any power saving software activated that would cause the monitor blank out? Check display properties? Sounds weird but have you checked for any viruses or spyrus nasties? If its hardware it could be many different things. Let me know what happens. Good Luck Tim
