Hello. I have an 8 year old Insignia NS-46L780A12 w/ screen problem. Hoping you can tell me what it might be. The very top of the screen seems OK. Below that it has horizontal lines running across the whole screen. And in the middle it looks like the color is messed-up on some of the lines. I've taken the T-con and video boards out and cleaned them off, and wiggled all the connections. I tried to record a short video of screen. Link is below. Thx. for your help.
