As of this morning, 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).

Does anyone know what is going on?

I've reset the TV to initial settings and ran the Pixel Refresher. Pictures attached.

Nope, bought it late 2017. What are my options?
 
I bought mine online. I registered it with LG and that states that it is 1 year.
 
Where online though, as the first 1 year is normally with lg with a further 4 years with the retailer you bought the tv from.
 
Never heard of them, most retailers like currys, John Lewis, richer sounds, Martin dawes etc all offer at least 5 years warranty on their items.
If there's no warranty then you'll need a TV engineer to take a look at it, figure out what board it is that's faulty, and get it replaced.
 
Thanks. How would I figure out which board is fault?
 
Try googling, but I imagine you will need a TV specialist to take a look and sort
 
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?
 
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.
