To know if the problem is in the new micro, you have to measure if there
is a hi, all the time, on the base of the rely transistor drive, while
pressing the on off sw button. Also the drive transistor itself could be
shorted or leaking
good luck!

Al. Someone mention the relay and may have hit it right. try tapping on
the relay while in the off state and see if the set cuts off. If so,
Bingo relay at fault. If not I would try and put in the exact Micro .
When you installed the new micro. did the set fire up at plug in or did
you have to hit the power button first.
