Question about Sony FD Trinitron WEGA KV-27FS100 27" TV
My TV will not turn off (by remote or manually). I have to unplug it to turn it off. When I plug it back in it powers up. No function on the remote works. The TV/Video button on the tv does not work. Here is where it gets weird: the TV volume buttons cycle through "video 1-4" when tapped, and control volume when held down. The channel up/down buttons on the tv make the screen goto "Video 1" but will not change the channel.......they only make it goto Video 1.
Check D1004 5v zener diode, if defective it can cause you this type of problem, also check D1003 and D1005.
part # 8-719-929-15 from sony.
these diodes are located in HS board, the one where all your front button are located in. by the way the HS board is no longer availableffrom sony
