I have an unusual fault that I personaly have not had before hoping someone out there may cast some light on it, I have a Lcd set that is not tuning in DVT however is tuning in analouge yet the board is not faulty .
I placed the board with another psu and got tunning . So whats the problem you say .. the problem is all voltages on the 17pw16-2 board that powers this set are all good , yet the board will not work on it's original psu so there must be a fault yet try as I might I can not find it .
I was hoping one of my fellow engineers may have had the same fault and found a cure , I dont know if I am being as thick as a plank and missing something obvious or I have found the original Gremlins TV from Hell ..lol please please save my thinning hair and give me a sign before I go completely doo lally .. Vortash ..Plymouth uk Rolling Eyes Rolling Eyes
