Having problems with your Flat Panel Televisions ?

I have an RCA L32WD22 that has picture but no sound. It wasnt powering on so I changed some capacitors on the power board and now it powers on fine but no sound, so I ordered a new sound board and still no sound, all connections are snug, what could this be??



Answers :

Make sure your power supply outputs are all within tolerance. Second verify that mute isn't turned on. Next, check and see if your model gives you the option to turn off the internal audio. Some sets give you this option for those who want to use surround sounds.

I was told it is shot but if I took the back off and took the boards apart and put back it may work.
