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.
