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.
