    TH42PX60U Vertical Color bands

    Wondering if this is panel failure? The colors of the lines change and sometimes it's a solid black bar the same width.

    Could the buffer boards have been affected?

    Thanks in advance!

      Panel issue--or more acurately, the COF chip attached to the panel on the Mylar film--They are made as an assembly and cannot be replaced separately.

      You'll probably find that the chip's heatsink directly under the faulty area is hotter than the others....

          Well, at least try to clean and reseat the affect ribbon cable to see if that clears it up, but that does look like IC failure.

            Partial Success Repairing Vertical White Bands on HP Z30i
            by lowteq
            Hello.

            I was given a HP Z30i LCD computer monitor that had several white wide vertical bands on it. I had another Z30i that was working and after a lot of swapping of components I found that the logic board, TCON board and associated ribbon cables were healthy. The problem was the ribbon cables that go from a long slender PCB across the top of the panel onto the panel itself. The problem connection was on the PCB side not the glass panel side. These ribbon cables are attached with some kind of heat set adhesive.

            I'm aware that this type of problem usually isn't repairable...

            vizio e65 e3 LED tv color vertical lines center tv only
            by viking509
            I recently replaced the led backlights with LB65041 LED Backlight Strips and after putting it back together the backlights work but there are only colored vertical lines only in the center of the tv. I can see the Netflix logo (jumbled) after a minute or less the screen went dark. When I turned it on again the lines were back. Then I replaced the t-con board but the same vertical lines in the picture. My question is what is my next step? Could it be a source tab bond issue? A buffer board issue? Could I have loosened a connection to the panel when replacing the backlights? Should I replace the...
