I discovered that if I plug in a computer the picture jumps non stop. So I replaced the input board as shown below. This fixed the problem but introduced another problem. The new board had the V-Chip programmed to block some shows. Now I have to get a remote control so I can wipe out the memory and hence delete the V-Chip programming.
Replacing the capacitors was a complete flop. I tried carefully wiggling the caps from side to side to remove them but in every case I removed the runs from the board. I guess I am staying with the new board as it mostly works. I was able to wipe out the V Chip programming with the remote control.
