Sounds like a high voltage power supply problem. With the TV on, check to see if CRT has a static charge on face of screen by placing back side of hand in front of it and feel for static charge. Also you could hold a piece of tissue paper in front of the screen to see if static electricity from the CRT attracts it. If no static charge is present, the problem is more than likely in the high voltage power supply. Unless it is something simple, like a loose connection, it would probably be cheaper to replace the TV. Do not probe around in the HV power supply while the TV is on--it could prove deadly.

Chances are your main board is bad, its where all the sounds are producted, a new board should correct the issue, its something you can install yourself with a screw driver, have the set unplugged for about a day before replacing the board so all the capacitors are discharged..you can get a new board at shopjimmy.

Check all inputs. Make sure they are properly connected and all of them are giving you this static. If this is the case you have a bad audio circuit in your TV. The odds are that your signal is bad though. Also try lightly slapping your TV to see if there are any bad connections. The sound should come in and out if this is the case.
