Samsung PN51D550C1F with color vertical line

[NUTIN2LUZ]

I'm not too great with repairing plasma TV and wanted some help in repairing this one. I have read about black vertical lines or any vertical lines could be a cause of a bad panel. Can someone help me with this?

I have a Samsung PN51D550C1F that has colorful vertical line in the middle and a faint line on the right of that. Pictures show in test mode. Any help would be greatly appreciated.

1st picture shows a blue vertical line with black dots.
2nd picture shows vertical colorful line with blue bar on the right.
3rd picture colorful lines on a blue screen
4th picture colorful lines on a green screen with faded bar on the right
5th picture colorful lines on a green screen
6th picture colorful lines on a red screen
7th picture colorful lines on a white screen

I've checked all the voltages and they are all in specs.

Have you tired to clean and reseat the affected ribbon cable from the panel to the buffer?
