That appears to be the case, when messing with the ribbon cable the line color would change. Also took a picture of the ribbon cable, at left is the suspected bad ribbon; at right is a normal functioning ribbon.
On the bad ribbon cable the "long skinny rectangle" area in the middle the top area seems to be burnt and on the good ribbon cable, the color seems to be more consistent. Would this be the cause? Is it repairable?...Leave a comment:

My bad, I meant I have replaced the D board and the buffer board. I didn't replace the C board. Any way to confirm the ribbon cable might be the issue here?Leave a comment:

UPDATE:
Replaced both C board and the buffer board but issue persist.
One of the vertical bar is almost permanently displaying green. At this point, perhaps the ribbon cable is the issue and based from what I read, the ribbon cable is fused to the panel so there is no repair.

Appreciate all for the inputs. I will try in this sequence: clean ribbon contact; replace C2 board; and finally replace D if necessary. I will post back with the final resolution. Thanks!Leave a comment:

Many thanks for walking me through this. I have reseated the ribbon cable and the issue remains after putting everything back together. Two vertical bars, now one solid black (happens b4 but could change back to a transparent color later), the other vertical bar continue to change color.
Would this means either the cable or the panel is bad which probably not worth replacing, or there is a chance the C2 board's CB8 "port" is bad which may worth replacing?Leave a comment:

Okay, the first pic below is the overview, the second is the focus on A board and below, the last pic is the CB8 ribbon off the C2? buffer IC board. When i pushed in the ribbon cable on CB8, i see reaction from the two color line onscreen immediately. Is this indicative of the issue? What are my next steps? I haven't try hard to remove the ribbon cable because it is locked in.......Leave a comment:

Hi Tom, thanks for the quick reply! There is a good picture of the inside of my set in the attached PDF, page 5. Where is the location of the C board you are referring to? and what connection I should focus on? thanks....Leave a comment:

Thanks in advance for reading this. This issue first started 2-3 months ago where the two lines would only appear occasionally and slowly getting worst, and is now displaying permanently. These two lines are color changing at times, flashing various colors, and sometimes in solid black which blocks the picture completely. These two lines seems to be "worst" when TV are first start up and a little "better" when warms up.
I am hoping to narrow down to a board or cable that I can replace. This set is a 42 inch so there is only two buffer IC board, but the two line...
