The problem is the convergence circuit.
Mitsubishi used two different types of convergence IC's in this series. The first is a pair of STK-392-570, the second is a single STK393-110. The only way to fix the problem is to replace the appropriate IC'S. In some cases the problem may appear to be intermitent or loose solder connections. Save yourself the anguish and replace the IC'S.
Getting the PowerSupply/ Convergence board
out to do this is tricky and I recommend a professional to do it. Hidden screws on the front of the heat-sink make it difficult to take out and you can break the board easily trying to force it.
