Only red pixels turn ons

[BearOnAShark]

Hi,

 

I have a 65” LG UHD TV UM7300 ThinQ AI which is a few years old at this point. 
 

Since a few months I have the weird bug that only the red pixels turn on, I switch the tv on and off and it fix itself. Sometimes i only need to do it once, sometimes I can do it for 5 minutes. 
 

What could fix this?

 

I tried :

- unplugging it and press the power button

- factory reset

- factory reset, unplug and press the power button

that sounds like some connectivity issue somewhere, aka some internal component has broken in some way.

 

as for what and how.. that's anybody's guess.
