Question about JVC AV-56WP30 56" Rear Projection Television
I have a JVC AV-56WP30 56 in. rear projection. Don't know what happened, but one day I go to turn it on, and I get no picture, just the power light flashes on and off and a clicking noise is heard coming from the speakers in sync with the flashing. It doesn't flash a certain number of times and pauses, just a constant flashing. The clicking gets progressively louder then stops after about 30 seconds or so, but the power light continues to flash.
I am experienced in soldering and would like to fix this problem myself, if possible. Any help is greatly appreciated.

What has happened is that your shutdown circuit relay has tripped and it looks like it also may have malfunctioned. This however is not the cause of your problem but a symptom. The cause of your problem is an over-current condition caused by one of the systems in your TV, I would suspect the high voltage power supply or the switching low voltage power supply. These are the first places to look, if they are not the problem then check the convergence correction amplifiers. Right now the shutdown circuit is keeping the TV from coming on. If you do not have a background in electronics I would advise you to have a qualified TV technician analyze and repair your TV.
