L42wd22 "no signal" and no audio

Exactly one year ago our TV did that. Now our TV is in the service center cause it has no screen.....just a plain black screen. However last year when we had it in we had that "no signal" message. It was not the same problem. It had something to do with wiring on the master board...thank gosh for warr. Otherwise I was told it would have been a $300-$500 repair.
Best of luck!!

TV has no sound

First try resetting by unplugging totally from the AC, then reconnect and try again. if still no audio, check all inputs to make sure its not a bad cable/sat box , next check for a speaker switch either on the back of the Tv or in the menu. make sure the cable box and TV is not in SAP second audio program mode. if these all fail then you make need the audio IC replaced on the main board

Sound keeps cutting out

Hello Shellyfoster:

The issue sounds like a firmware update is needed for the small signal board.

HDMI Cable - No Sound L42WD22 RCA Flat Panel TV

No sound and a digital picture. i will assume you have no signal on analog rf cable. Thomson(RCA) have been having problem with these sets. The trouble stems from the digital cuircit board. We see alot of these. You used to get the digital board.. they are not availble.. so rca found the component on these that fail.. A VERY SMALL surface mounted fuse. With a lighted magnifer and some fine tip twezzers. we replace these fuses on these boards. Do you have any soldering experence..
