"Doesnt appear to be any damage to anything. Which board is the driver board??"
So you remove the LCD frame to get to the T-CON/Tab bonding boards?Leave a comment:

Re: Hitachi 50HYT62U no picture
The LCD panel has integrated T-CON board and also located at the bottom edge of the LCD panel which is easily damaged by the cleaning liquid, so inspect the T-CON/Tab bonding board for damages and also check the caps resistance as suggested.Leave a comment:

Guess you could test your caps on the driver board for shorts or very low ohms.Leave a comment:

Re: Hitachi 50HYT62U no picture
What do you get on the screen if you only have one ribbon cable between LCD panel and the T-CON connected one at a time?Leave a comment:

KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help. -
Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
No picture but you hear the TV static (white noise) playing loud and clear.
The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
But it seems they didn't get too far and just left it.
When I first took a look I was amazed at how pristine the inside looked.
Its as if the TV had been in a time capsule.
Caps looked like they were just pulled off the self.
Copper coils had no sign of corrosion on... -
So here we go with another screen short TCL. For this exercise left and right will be reference looking at the screen.
The person I got this TV from said the color was bad in a vertical fashion about 1/4 of the way over the left side of the screen. Shortly after the symptoms below started.
Power Supply, main and T-CON board are working.
Symptoms: The TV has backlights but no picture with both FFC's attached to the T-CON and does not respond to the remote or buttons, and the TV appears to continuously re-boot.
Unhook FFC from left side... -
Hi
Really stuck on this TV
I'm thinking it's a bad screen ?
Voltages all seems good
Tcon 12v ok
Remove one tcon cable at a time no half image on the screen just backlight and no picture
even tried the tape trick still no luck
Thanks... -
When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?
