[anna1980]

Noob alert !!
Got a UE46C8700 tot try to repair.
But I don't know of this is repairable at all

Got all colours of vertical lines on the screen. Sound is okay
Could this be a bad panel or is this more of a tcon problem

Ok sorry you never replied so I ass-umed (me ass lol) that it was the same Tv. This looks like the panel tab bond issue to me personally.

Does the t-con have one or two ribbons going to the screen? What happens when one is unhooked?

@ReeceyBurger123 No problem. I should have closed the other topic the right way
@johns1mj Yes it has to 2 ribbons going to the screen.
I've have attached pictures on this message for the result.
When I disconnect one ribbon there is a residual image left which fades in about a minute. After that it is black. Same as on the other side.

Today I've updated the firmware and now it starts. At first I get an image with horizontal stripes and after some time vertical also arrive. But now a new problem has arrived. Sometimes residual images stay on screen. Not long and now always but it is there. I've attached a motor race image as example.

1) When talking about a panel bond, should the vertical line not be from top to bottom. On my screen its about 14/15th of the screen and about an inch from the bottom it stops
2) Could this be something else than an panel/tcon. Could this be more a mainboard

If you have an oscilloscope you can look at the lvds signal coming from the main board with a video feed, although this does look like a bad panel
