Why do I have wierd, red "topographic" lines on screen?
Both of my Samsung LCD TVs are having the same problem, which seems to be sporadic. There are red lines, looking like lines on a topographical map, throughout the screen. My phone does not have a great camera, but this is what the TV looks like:
I previously changed some blown capacitors on the power supply (this TV was one that was recalled, but it worked, and the person who gave it to me was throwing it out), so I am competent to work with PC boards and components.
This happens thru the cable box as well as DVD and streaming inputs.
