Question about Televison & Video
L would first make sure the speakers in the set did not get switched to OFF and also see if a DVD connected to one of the rear inputs has sound or not.
I know this set as saw one two weeks old first with no sound.
The entire audio circuit is on a single board (all of it) that is sandwiched between two other boards.
The first one was new so I Called Jvc and did some checks as they indicated---problem was on the audio board and since no individual parts for any board are sold--they told me to order the board--the board was on Factory backorder as a lot of them failed.
The customer did not want to wait so since a new set they exchanged it----Then they notified us to cancel the part order and dispose of the set in any way we wanted--they abandoned it to us.
I had our parts person keep the order going for the board..
l received the part about a month later, installed it (40 minutes) and had a 100% nearly brand new set that we later sold with a warranty--ours.
Most shops should be able to detect if the board is bad---you will have signal and audio coming in and if none at the output--bad board.
If I remember that board wholesales for around (at the time) a hundred dollars or a little more.
Hope this helps
