Picture is very dark.

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.

From some of the forum threads I've read about this, it seems like there were early issues due to bad firmware, but they have all be resolved with the recent updates. It also appears to be very easy to replace the hard drive. Just swap it out, format from the menu and you are done.

u will neeed to get it updated

A very dim picture in this case may be damage to the power supply of the set---If a LCD set it may use back lights of some type--if not on or at full brightness the picture will be very dark.

If I was looking at this set I would open and check to see if voltage for the back lights is correct first.

have sound but picture is too dark to watch on tv

Try replacing the RCA cord (yellow,red & white).

hi,
Just a guess,under the power button, inside the the flip[ down cover is a light dimmer,you can turn this on and off,in advanced settings under video,a flash light will trigger the sensor to see if it works the dimmer,if not it could be that circuit or your power supply needs work,I hope this helps!

Sounds like a bad screen asy,part number 204809,must use the generic,or you could have weak tubes,if so you may just need to turn up the screen drives,this part is located in the right top of the set with the back removed,if no cracks are present adj. the three marked screen's,turn the color all the way down in your menu and adj. for a black and white picture.
