Thought you guys may know the problem... I have a spare old 42 inch Philips Plasma I bought about 4 years ago (yes it was one of the first and did cost me an arm and leg!) So what happened, well after it had been replaced 4 times in the first year everything was fine, until it had run out of warranty (typical!) The plasma switched off moments after switching on, also (which I think is important) occasionally the screen was all over the place in respect of the picture - I will try and describe it later in this post. I discovered that it was a failing fan on the set. So I replaced all the fans, direct from Sunon, and have cleaned the set up, after about a week of testing to try and get the set back on, it finally mananged to do it this morning, and stayed on, and I have sound! HOWEVER..... I have a rather interesting problem. There is no picture! Well when I say no picture, there is something on the screen, mainly Green/yellow bars, dots lines.. you name it! When I connect my laptop up, i can "almost" make out some sort of very jarbled picture. I don't know whether anyone has had a similar problem (I doubt it), but if anyone has, or if anyone could give me a clue as to some probably causes, hen I will look into it further. Don't worry, i love "tinkling" with things... and at least the set switches on now!
