Question about Sharp AQUOS LC-62C42U 42" LCD TV

1 Answer

My sharp aquos LC-62C42U is part of a home theater system. Everything was fine this morning. I turned the system off and when I turned it back on several hours later, I have no audio. I checked my receiver by setting it to tuner mode and I instantly have audio, so my presumption is that the receiver is fine.

On the set itself connect a DVD directly to one of the rear inputs to see if audio that way.---if so set is likely good.

Check hookup etc and in set menu look to see if speakers for some reason are OFF> or set to external.

Please be aware that this a big problem on this unit. The insulator material used by sharp to between the IC's on the AV board both on top of the boards and underneath the the AV pcb is failing. This insulator is mounted to the IC and under the metal heat sinc. Remove the back and pull the AV Board out of the unit. Use zylene or alcohol and clean all of the grey insulator from between the pins on the ic and order the replacement insulators from Sharp. Most times this will correct the no sound problem. Sometimes this has also damaged the AV pcb and it will have to be replaced. The parts that should be replaced come in a kit with sharp part # PSPKIT663WHZZ. If the kit is not available the 2 parts needed are PSPAZA663WJKZ AND PRDARA216WJFW.

Turn the power off to the television and everything connected to it. Count to 10 and just plug the television in. See if it works OK? If it does, start turning on each item connected one by one. If it comes back just on the television, I would contact Sharp.
