Nope. It appears that you now have a main power supply issue since the set is dead.

My Sony KDF-42WE655 has no video and no audio. The green standby light just flashes continually. There is a popping noise coming from the lamp compartment. If the lamp dies, do you lose audio as well?


hi,
You've got it right, it seems you need to replace the lamp. If the lamp is faulty the unit will not turn on. See the instructions manual for lamp replacement..

My front display lights just went off it still works just no lights can you help me


It probably needs some(2-4) 12V fuse lamps (lamps that look like fuses), could also need a couple of 12V zener diodes. Some JVC models can be a little tricky to get to the lamps. If you want to diy, you can order the lamps at mcm electronics.

Normally the symptom, audio/no video is the DMD. The light needs to be changed. Contact RCA at 866-465-7157 for a servicer in your area.
