Please take a look at the pictures and tell me what you think. No audio at all.
Set does not ever show the amber standby vizio but that could just be burnt out. Power on and the white vizio comes up.. no start up jingle.. screen comes up with vertical lines, white vizio goes out after about 10 sec. Screen stays on but times out after a few minutes. Sometimes the white vizio flashes on and off... and times out. But next power push and the screen lights up as below.
I was pretty sure this was T-con but now not sure. One site that sells the tcon says none of their boards cure vertical lines. All voltages on the ps look good. There is only 24, 12, and 5. Nothing like the Plasmas I have been working on.
I tried unplugging main board but would not power up at all. Tried some freeze spray.. no go. Also flexed the screen looking for bond issues.. no change what so ever. One more thing.. I noticed the ribbon cable on the right side of tcon board does not insert as deeply as the left side.. Reseated both with blue line still showing on right.
So do I have a bad panel or??? Set is 55 inch and about three years old.
