My AV-48WP74 JVC TV is making a pulsating sound and then shuts off. There is no picture or sound. How can I fix this problem and get my TV back working again?!


i'm having the same problem. I looked at the power board where the power directly comes in and there was nothing wrong with the power coming off it going to the main power board that goes to everything else on the tv. At first I thought it was a cap. but I'm not so sure it isn't something with the bulbs for the lenses.

No sound on JVC AV-48P575 48 inch rear projection TV


Try going into the menu and find something called, "center channel input." If it is on, the sound will not work. Turn it off, and the sound should be restored.

Sounds like you lost the High Voltage. The beating sound is the power supply trying to start up. After a predetermined time it will quit to protect the set. This is a very common problem and typically not that much to repair. If you are not an electronics repair technician you should find a reputable repair shop and enlist their services. I would not think the cost should exceed $150.00 to repair. Good luck.
