As an update. The problem is now solved. The issue was with the Main Board. Bought a new one of eBay and after replacing it, the pixelation is gone.

I'm thinking that the issue might be with either the main board or the T-Con board, but not sure which. I don't want to buy and replace both so does anyone know which one it might be?

Hi @George Hofmeister, no it hasn't. I turned OFF auto updates.

As of a few days ago, my OLED65B7A started showing strange pixelation on the WebOS UI. My Directv that is plugged into the HDMI port shows just fine but using the WebOS UI to scroll through apps or look at the settings, or even inside apps like Netflix or Prime, etc., the strange pixelation occurs (once a Netflix/Prime show starts, it's fine). It's as if the front interface layer or something is broken but not the main viewing screen/area? Does anyone know what is going on? I've reset the TV to initial settings and ran the Pixel Refresher. Pictures attached.
