Question about JVC HD-52G786 52" Rear Projection HDTV
Not getting any sound through the television speakers
Either speakers turned off, or an audio problem which was common on this model----the entire audio circuit is on one board which may still be available.

Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!

your TV is having a power problem. The power supply board is defective that's why the TV won't power up. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on.
If you know about TV repairers, I would suggest that you open the TV and read the power board/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.
