If you could answer the below info requests please this will help me a lot thanks!Are these vertical lines visible if you press the menu button of the sets own remote control?can you see the lines over the menu display?
OK please give me the full story of the original fault why you changed the t-con board and anything else you can think of so I can get a better understanding of the trouble.
Do you still have a picture on the set? The lines are over the picture? You said the display was white? I am a bit confused here.
What I would like to know is... how can you test a T-Con board?
You cant "test" the T-CON board if it has a faulty component on it has to be determined by swopping the board, their is no test procedure which is why I am asking questions to the fault, if by swopping the board the fault clears then you know the board is indeed faulty or not, flat tv technology in the main is a board swopping exercise with no checks or tests other then using the menu as a signal injector this tells me a lot, however your reply so far on that is you have a white screen which is what I don't understand.
>>the picture stays on for a while then horizontal lines appear then screen goes black<<Does this happen every time you turn it on? Picture, then horizontal lines, then black?
