Thanks Ken for the tip. I wish I had that luck with those opto
couplers. I seem to change those little rascals quite often, and rarely they
fix my sets. I am jealous. These are the kinds of tips that help us all.
Please everyone, send your fixes in. The questions are still outnumbering
the fixes twenty to one. Are we fixing any sets? I will file this one
though.

Friends,

Thanks to all your helpful suggestions.  On a SWAG, I replaced opto
coupler IC901.  Set ready to go out the door.

I hope someone has a clue on this one.  Push power, set powers up and
shuts off.  Does develop HV.  Actually goes into shutdown.  Set must be
unplugged first for the cycle to repeat.

Everything we have checked is good.  If we jump the relay the set runs,
but with slick screen and no audio.  I suggested my tech replace the
EEPROM.  Pulled one from a junker.  Set worked.  Had video and audio.
Wasn't the right EEPROM, so many things didn't work right, but I was sure
we were on the right track.

Ordered new EEPROM from Tritronics.  Acted same as original.  Ordered
another EEPROM and the uP, thinking they might have to be replaced
together.

Still no joy!  Don't know where to go from here.  Please, help if you
can.
