No sound on 52jvc hd-52g886 - JVC HD-52G886 52" Rear Projection HDTV

UNPLUG THE TV. then remove the back & you should be able to see up to the speakers.

It almost sounds like a setting issue that might require the proper remote to control. You mentioned "tv input" are we talkin RF/Cable screw on input or rca type composit video input? and essentaily yes to your question all the inputs are microprocessor controlled as well as the entire functionality of the set. You can probably pick up the correct remote for a few bucks on ebay or elsewhere on the net.

usually it is the lamp this set uses, has it been replaced or is over 2 years old?

Changing the contrast will also help brighten your screen. For best results, try changing the contrast and the brightness, to find the perfect combination for your needs.

you need to conect an other lead with red and white ends into tv audio input and the other end into audio out on the equiptment
hope this helps and merry christmas
