I didn't want this thread to descend in to utter confusion like the last grand adventure I'm at fault for, so left and right are designated when looking at the front of the TV, at the panel in this thread.
So this UN50H6203AFXZA arrived with sound, backlights and no picture. I did the Left/right isolation procedure. As expected the left lower side was the location of the panel fault. I didn't remove the bezel or look for panel damage at the left lower support.
I started by insulating 4 of the contacts on the left side of the left FFC cable from the t-con to the source driver board. At the 5th contact the picture popped back up, but with horizontal lines. It ran for a while, 20 minutes or so and I noticed a black semi-circle developing about 1 1/2" up the left side. I touched the panel there and it was very warm.
Bottom line, I kept the original FFC cable and replaced it with one from the parts pile and cut through 7 traces on the left side, just under the T-CON. This is what it took to restore a watchable picture but it still has very faint horizontal lines and colors in or close to the red range have lost color strength. For a rescued TV it looks really good for the most part.
So here are my questions.
Has anyone reading performed this work-around on this model TV, and how long did the TV last after that? Or does anyone have an opinion of life expectancy?
Should I be concerned about damage spreading further in to the panel causing further problems, or did the work-around take care of it?
I feel like 7 traces cut is getting to the end of the road. Can I, or better should I continue cutting more traces with the hope of getting rid of the very faint horizontal lines? Is there any chance cutting more traces might help the color strength on the left side?
For what it is, overall when there's a picture on there it's good enough and if someone else does the procedure this may give you an idea of what you may get.
