Got this 4k LG.
Shows what I would assume was a faulty mainboard.
Multicoloured raster on all inputs including coax, sound remains, displays perfect menus.
I have several TCONs in stock for other UF models, some compatible, some not. Some made the menus and start up image black and white. However none changed the fault. (I didn't think it was a TCON fault but worth trying)
So I bought a replacment main board.
And of course the fault remains.
This does appear to be a common fault on these 4k UF sets I've seen a few others for sale with the same issue.
However I'm not convinced I've bought a bad mainboard. Im leaning towards bad panel, purely due to the way it starts up. It displays a thin multicolor horizontal line right at the start, running right along the top. For about a second. pics to follow after this post.
Personally never seen it before when the menus are ok but the panel is bad, so this could be a first.
