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....

I remember scrapping Three of this model for exactly the same issue--In One Day!

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.
