Does the lcd screen have a glow to it ? Or is it really dim if u get real close to screen u can see images moving ?
it it has a glow to it you panel lighting is fine but you control board is bad. If you have a dark screen and see faint images you panel back lighting is out u can check the power with a meter at the connection to inverter board on panel.

SOURCE: No sound on LCD tv
We have the RCA L37WD22 tv. We bought it 4 months ago and much to our dismay, the sound went on the weekend and the screen shrunk. We had to take it in to be fixed. We were told it had shorted out and that the fuse needed to be replaced. We were also told that an upgrade was put into it. We have a one year warranty, but we are going to look into buying an additional warranty too.
Hope this helps.
