I think you have to have something plugged into video inputs or RF INPUT for sound to work. Otherwise you get a blue screen and it says no input. or not available. Does this set have an off air HDTV tuner? IF it does, try hooking it up and see if you get sound then. Good luck and that should solve you problem. If not, reply back and we will continue with troubleshooting. Thank You Jay

This kind of failure is very common; that is why I suggest that one should keep the old CRT TV, buy a converter and put them both in the garage or basement so they are handy when our s*e*x*y new sets go belly up.
With fair confidence I can say that the main power supply has failed.
If you want to try this on your own, it only will require the removal of a few screws and a flashlight.
- Unplug the set overnight. - Remove the rear housing - Use some logic and these tips; look for a separate board with larger than average parts on it and seems closer to the power cord than others. This will be the power supply.
Check the board over for something that looks like a part number and record it. If you find more than one, one of them will be the bare board number, the second (sometimes on a sticker instead of printed directly on the board) should be the part number for the assembly.
Search for the Westinghouse service company nearest you and call them with this info. Ask if they repair these or just sell new ones. If it is the latter, don't pitch the old one, continue to look for a repair service that will take it on after you have the new one in place and can watch your favorites again. The new supply will likely cost between $90 - $150 and with a little common sense, most anyone can remove and replace these in the set. Expect any repair to cost about the same as a new supply; US technical labor costs more than Chinese assembly labor.
These supplies can be as reliable as the primitive older type but companies refuse to use the high-grade components necessary to give them a long life so they fail much sooner than the old, less efficient kind known as 'linear' supplies.
