I've got a 13in TV that from time to time will - for the lack of description - has screen burps. When this happens the screen fades out and the sound cuts in and out. Is this a TV tube going bad? It seems to happen during certain commercials and on some channels but not all the time. It is a periodic problem but very annoying. Any ideas?

Since television sets no longer have tubes in them, the problem can be isolated to an integrated circuit that handles AGC (automatic gain control) or Video Output. I perceive this problem as a bad solder joint that reacts when the temperature gets high enough to cause the board to flex.
Find the circuit board in your TV set, use a good 60-40 solder, and a low heat iron, and resolder the connections on the board. The problem will go away.
It is caused by a displaced ground that disconnects when the board flexes under heat. A little solder and you are back in business.
