Dear Xrunner:
--Tom is too modest, he has actually fixed 100s of TVs and monitors by proxy over at BadCaps Forum. He helped me fix a discarded Panasonic PS-50PS14 50", which had exactly the same problem as yours. First he had me re-seat the connectors and then he recommended a board replacement, which cost $40. This fixed the TV, which made a great Christmas present for my brother, and it has been on 16 hours a day for 5 months now. Tom is but a humble university student and yet is one of the most helpful of the great bunch over at BadCaps. Laurels and Kudos. His answers are unbelievably well researched and exceedingly prompt. Tom and his comrades at BadCaps, as well as DJ have taught me almost all of the little I know, as a "monkey see, monkey do" part swapper. I have now fixed 20 or so TVs and monitors, (yes I am an addict) which I give to my friends, or donate to charity. The ones I cannot fix I flog the parts on eBay. My latest project is the repair of a Vizio M320SL 32" LED TV, which I will use as a monitor to replace Olivia 26" that I am using as a monitor at present, total projected cost $100. I will post the Vizio project at BadCaps and here.
