When you say no picture, is there any sound or noise coming from rear of set when you try to turn on. If so then you have no high voltage and maybe a cap in the HV line that is bad. If no sound at all, then maybe a fuse or open resistor in powersupply.

If it has been moved or bumped recently the sound you are hearing is the main HT lead that has been displaced. TGhis is a blasck lead with a rubber disk surround at its end that fits into the picture tube. Do not touch without turning TV Off and using rubber gloves to reinsert.

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.
