Encouraged by the two previous repairs guided by your expertise, I am now trying to tackle an image display problem on a Plasma TV.
The set powers up normally, sound OK but the image is broken, jumping, with many vertical lines (thin coloured and wide black). Same also when OSD Menu is displayed.
All insides look nice, clean and in order. No visible signs of burning components, or swelling caps. No blown fuses, connectors seem in tact, Va and Vs voltages appear correct.
I would really like to hear your opinion on it. Any suggestion for any tests to verify/narrow down the problem?
I attach some pictures of the boards layout and actual snap shots of the screen display.
Your help would be much appreciated.
