Someone posted this on AVForums and it is the kind of thing worth reading before you panic about your own set. He noticed odd markings across the top of his HZ2000, described as looking like a tear pattern, as if a sheet of paper had been ripped in two. He only spotted them after the set ran one of the long panel maintenance routines, the ones that trigger around every thousand hours rather than the short one that runs when you switch off. Started at the top right, and he thinks it has spread over the last few weeks.
Worth separating two things here. The long routine does not damage a panel. What it does is rewrite the compensation data the set uses to even out the subpixels, and occasionally that makes wear the TV had previously been hiding suddenly visible. So the timing can be a coincidence and a reveal at the same time. That is the optimistic reading.
The part that argues against it is the spreading. Compensation data does not keep getting worse on its own between runs. If the pattern is genuinely growing week by week, that is the panel, not the routine.
Before going anywhere near a service call I would put up a flat 5 percent and a flat 20 percent grey slide in a dark room, from a USB stick rather than an app, and photograph it. Then check it appears identically on every input. If it tracks the panel and not the source, you have your answer and you have evidence. A set of that vintage is well past warranty, so the photos matter more than the phone call.
Anyone here had a Panasonic OLED develop uniformity marks along the very top edge specifically? That location seems too consistent to be random.
