Samsung UE40J5100AK Bad Picture

[Bloopeta]

Have a Samsung UE40J5100AK, and the picture is bad on one side of the screen. I have tried to photograph it best I can, the colour seems off and darker than should be, and not as sharp?

Just wondered if this is more likely a Tcon fault or a panel fault? Or if anyone can shed some light on what may be the problem?

Most likely LEDs (when degraded, they began to shine in blue)

Its not an LED fault unfortunately, its hard to show on pic, but the picture isnt right at all, writing for instance isnt sharp and crisp as it should be.

I change alot of backlights on LGs and Samsungs that have turned blue, so know what that looks like

could it be a tcon issue?

Orangey image is bad panel. Connect one side of tcon at a time to see if one side is good. If it has side tabs, rip them off the bad side.

side tabs only in bigger panels.

Please see attached pics.

maybe try the tape cut-off method, could also check the caps on the panel driver boards for shorts or very low ohms.
