Thank you Charles for your reply, here's what I have so far.....

The R505 resistor is a 3.3K ohm/3 watt resistor....and the Q502 transistor has a part # of 2SD1556. The question I have is where are they located in the set? Is there a board I can remove and take somewhere for service? I paid a repairman to come out and troubleshoot it, and he did, but they want an additional $475 to remove and replace these two little electrical items. I realize one might have to remove old solder, or solder something in place, but if I had a schematic on it....I would try it myself. Can you help me Charles

I just read that you no longer have a schematic, my bad.
