[Tdiamarelo]

Hi folks!

Have an Lg whit something like interferences...
Lines and image displacement. Could it be a bad T-con or motherboard or just a grounding fault?
For better understanding i made a video whit the issue.

Looks like a panel problem.

Or is it just a bad connection on the t-con?

Bad panel.

Re: Lg 55UF850V lines and image displacement

input a video test pattern like smpte color bar which gives a full spectrum of colors along with a fixed pattern so that you can readily see issues. At this point, the limited pictures appear to indicate a panel problem but perhaps a poor connection in the intercabling of the boards and panel.

Problem SOLVED.
Bad Main Board.
Replaced the main board and set works fine.

So you no longer see double images (Non Programme) when the new main board is replaced?

Re: Lg 55UF850V lines and image displacement

Correct. The double image was coming and going only for 1 second or even less.. and all the other lines also, and bouncing around the screen, that is why I posted the Video file but is not allowed or accepted by the forum.
Maybe a faulty image processor from the main board.
