About all I can say is : Check the power supply
I think I've seen one dead PTV775 in 3-5 years.
Actually, I think the B+ diode opens on some of these units, and another
diode tucked in "real close" to the IHVT has been known to short. I wish I
could give you location numbers, but this is a "mind e-mail file" with a
visual attachment. Good luck and let us know what you find.
