I have recently replaced 3 buffer boards. (Up/Down and Main) The TV worked for a week and out of nowhere, this white band came accross the screen (as shown in pic) and doesn't go away regardless of input device. The pink pixels within the band slowly disappear, but once they're gone, they reload like shown in the photo.
I've put a few hundred dollars into this unit after only two years. I'm reluctant to taking it back into the shop and spending another $150 for a diagnosis. At some point, it's gonna be better to just cut my losses.
Does anybody have any idea what could be causing this white band? I'm just trying to weigh my options.
Really appreciate ANY thoughts.
Thanks in advance!!
