I have a sanyo tv I spent good money on a few years back. Just recently it's flickering a green screen on all inputs and even on menus.. tv plays fine but the picture will cut half way flickering. Can somone tell me the posable cause before I start throwing parts at it... ik back light and screen itself are ok bc it does work fine for 5-15 mins at first

This looks to be an LG panel, so I would guess another mainboard with bad solder.

So are you saying the main board that all the hdmi and other inputs are on?

That is my guess, and the first thing I would check if it were on my workbench.

Not a t-con board? I was looking at board prices for this and I don't wanna be buying un needed stuff. Thank you so much for the help so far

yes, confirming a second time that I really did mean the main board.

If you don't want to buy unnecessary parts, you should probably take it to a pro to properly diagnose it.
