Samsung PN50C430 Plasma TV distorted image

[BobSrunkel]

Hi all I have attached a couple of short videos of my parents Samsung PN50C430A1D. I can't really describe the distortion so I was hoping that someone here has seen it before and can help narrow it down to a particular board. The menus and the test screen look mostly ok. Anything from the inputs looks distorted. Tried two different devices on HDMI, AV and component video inputs, all distorted.
I've been working some long hours lately so don't think I have abandoned the thread if I don't respond for a while. https://youtu.be/5Ojj1-jG9H0

The fact that there are lines in the test screen makes me believe it's the logic board. Even though the symptom looks different than it does on the inputs.

Wait there, your not running the control board tests. Unplug the Lvds connector and jumper the auto gen pins on the Control board and power the set up. If they are not there Mb is faulty. To me personally looks like your Mb anyway.

Good call. I was thinking that was the logic board test and not realizing that the image was being produced by the main board.

Thanks for the replies! This could take a while. The TV is a 2 hour drive from here and I don't get up there every weekend. Looking on ShopJimmy, and for the cost of a main board, I would be willing to chance buying one if it looks like that's where the problem is. There are several part numbers so I would have to get my Dad to pull the back off and get the numbers first.
I'll look up the control board tests ReeceyBurger, will that prove the control board good or bad by itself?
