Lg 60pz550

[zlogan]

I have an LG 60PZ550 that was manufactured in 2011. The fuse blew on the Z-SUS board and was professionally repaired about 5 months ago. Everything was working great until this problem occured. Everything works on the TV with the exception of 3 inches of vertical darkness on the left side of the screen. Inside the darkened part are thin vertical colored lines. I replaced the Y-SUS board but the same problem exists. The same problem exists with all inputs, different sources and cables. Any ideas what the problem might be and what board might be giving me this problem. Thanks. Here is an image of what the screen looks like. Also with the image not sure why it keeps showing upside down when I attach it. It looks completely normal on my computer.

You can check the flat cable that goes from the panel to the X board for that area of the screen but I suspect its the panel (ic on flex cable) that is bad.

I connected then reconnected all the ribbon flex cables connecting from the buffer boards to the panel. I had to remove a long strip of aluminum heat sink mounted over all the ic flex cables. Unfortunately I couldn't access these cables while the TV was on because the heat sink was in the way. This didn't fix the problem. This TV is only about 3 and a half years old. Do you know if these flex cables with built in ic's be replaced ? If not I guess I will strip the boards off it and junk the rest. Anyway Thanks R J, I appreciate your help.
