RCA F27665 TV

The sound on my TV was working fine and while I was changing channels the sound went to all static. The picture is fine. Not sure what to check for this. Thanks.

First thing to do would be to

First thing to do would be to go into the sound or audio menu to put the set into the mono mode and not expanded extended or stereo. If the sound is good then the problem is in the sound IF or the stereo processor circuit.  If its still all static then  see if you can take an audio output from the RCA jack in the back of the set and connect the sound through an amplifier. If the sound is good there then your sound processor and switcher is most lily good and theres a problem in the power supply feed line thats supplying the B+ to the audio output IC or the audio output IC is defective itself.  If your not a trained technician A TV set is not a place you want to try to save a few bucks and try to fix the set yourself, as theres way to much Hi voltage inside these sets , to be experimenting with. Please seek out a train tech to assist you with this repair. Good Luck
