Vertical colored lines appear randomly
My tv screen shows vertical lines sometimes and even turning off and on again doesn't fix it. It does not depend on the video source, as it also exist on the tv menus. So it has to be a hardware failure, but I want to learn what can cause this and how to debug it. The lines move (when the image moves) and their colors correspond to the actual colors of the image that should which should be visible.
The effect can be seen here, but that is not my tv. It just shows the same symptoms: https://www.youtube.com/watch?v=YMbDogJr...
