In my tv is 10 years old and by the 2007 we replaced with new board(Only the CRT is the old one). Last day I was switched on my tv only sound only came and no picture. I can able to see the menu setting in TV live volume increase and decrease, Chanel nos etc. When I remove the external cable connection the display comes like blue screen(looks like the CRT is ok). When I inserted the cable the blue screen goes off and became black color during that time the audio of the tv is good. Pls help to solve this problem.
I was opened the tv and seen four IC is there, CD7680CP,CD7698CP,24LC04B and one more ic cannot able to find the IC name because its past some paper. No evidence of burning and all.
Pls help to solve the problem any one.
