Lori:
Probably not a "tube" problem (which is good because tube replacement is
cost prohibitive) but more than likely there is a circuitry failure or a
heat-intermittent component...... an experienced tech with the proper test
equipment and troubleshooting procedures should be able to repair the
problem...... or at the very least you should obtain a repair cost estimate
so you can make an intelligent repair decision.

Thank you very much!
Another note, the TV was off all night, so now it looks better. Once it's
on
a while I expect it will get worse. Don't know if that makes a difference.
