    This certainly appears to be the problem and the fix even for a non electronics type guy looks less laborious than carrying the set out of my basement.
    This is the second time this has happened and I think probably when I had it fixed last time only one STK chip was replaced

THis is a convergence problem that can be either poor solder connections on the convergence ICs or defective ICs. If you can solder, try resoldering the pins first. If that fails to resolve the problem, replace the ICs. These ICs are large, black and attached to a heatsink. THey should be marked STK392-110.

Keep us posted.
