Found the answer to question of "picture but no sound," so hope someone has had this, and found answer. TV was on, but only use to watch DVDs, and DVD player was off. Heard "crackling"? noise so pulled power plug. Could not find anything that looked fried, except a cricket in the power area. Fuse was not burnt. Will not turn back on when plugged in; only beeps in power area. Have schematic, but could not find safely stored owner's manual. Ordered one, Service manual not available. Hopefully just needs a reset?
We have the same model - tv won't come on and we hear a loud beeping sound. sounds like maybe it needs o be reset. Does this sound familiar and can you offer any assistance.
I have same problem. Did you ever find a solution?
