UPDATE:
OK I unsoldered the tuner as suggested. NO GO.
I also swapped out the LM7809. NO GO.
I guess I am gonna need a print for this. Anyone have one?
I will gladly pay for shipping and copy cost!
I really believe that its a X-Ray problem. It clicks on gets high voltage
then turns right back off.
Good luck, God Bless
