Horizontal greenish lines on Samsung UN55D6050

[bobbygiammarco1988]

I just replaced the T con board and lines still exist. They are constant, they do not move or ghost. They take up most of the display, more toward the right and get faint as they go left. Any Ideas?

Have you checked the tab bonds on the display?

I take that back. I don't think the tabs would be bad here yet.

sometimes you get a dud, could still be the tcon could be the mainboard, hard to tell at this point.

D series is known for bad panels.

I checked all tabs. Here is what it looks like. Lines do not move position but seem to flicker. Power board checks out. Tested all components on it. Nothing but clean power. Working upside down sorry about the picture

Similar symptoms have been seen before and are sometimes caused by failed panels (not tab bonds, just plain old panel failures, the driver chips on the tabs failing.) Worth checking T-con for obvious faults, may be worth swapping for 55" screen but hit and miss as to whether it'll fix it.

Also hard to see but on one of two ribbons from the t con to panel, there is a pin or two that seem to have been damaged but all pins checked to be okay with the meter and when I swapped the two, nothing changed. My next guess is main board or bad panel

Yes I figured that. Can't fix them all I guess. Thanks for the help
