I've got a Sony GV-9 8mm VCR / LCD TV combo that I'm trying to repair.
It had the usual leaking capacitor problem. I've replaced all the
caps and fortunately there wasn't any significant board damage. The
VCR and tuner work fine, but the LCD is just blank without even the
slightest flicker of video, or noise (the back light is working).
I've checked around the LCD very carefully for circuit board damage,
open fuses and other obvious problems. Without a service manual, all
I can confirm is that sync and video are going to the LCD driver and
at least something is going to the LCD panel.
I've been looking on ebay for a junker with a good LCD, but most of
the broken ones seem to have the same blank screen problem. Is there
a common cause of this problem that anyone here knows about? It seems
odd for the LCD to totally fail like this. It's clearly seen very
little use and has never been dropped.
