First, thank you for reading this and possibly helping me out! I appreciate it!
Let me start by saying I love Panasonic. Had a 50 inch plasma for 10 years and then finally switched to the 4K 55GZ950E last summer, after trying the 65GZ1500 but that made me nauseous and car sick. Too big. The 55 inch was amazing. In every possible way.
Until this week.
At night, when the living room was dark, certain movie and series scenes started to cause flickering when it was dark. Two days in a row. For example between two scenes when the screen goes to black for a couple of seconds, it got lightly, large, flashing areas on different parts of the screen (exhibit 1), then another scene where a house was filmed at night, the skies above it (dark with some clouds) gave the same flashing. As if the aliens were about to land. But they weren't. This show wasn't about aliens. It looked like watching a screen with a bad and slow refresh rate, but only in dark/grey areas. Pure blacks are fine. Then another scary movie scene in the car, where the darkened ceiling started to flash and flicker a bit as well. Pausing the movie/show made it stop.
When I turn on lights in the living room, it's much less noticeable.
Here's what I tried to fix this. My apple TV (4K) goes to a 4K receiver and then to my tv. Plugging the Apple TV directly into the tv didn't fix it. I watch in THX cinema or THX cinema bright, with all help turned off (so the standard settings). But switching to the other picture modes didn't help. Changing the output of the apple TV to Dolby Atmos didn't fix it either. Switching HDMI ports didn't help either. This time, in some of the scenes, pausing them no longer helped. The flickering continued. Only on the dark but not black area's that are not moving.
Then I decided to switch my Apple tv to the other 65 1500 Panasonic I still own but rarely use. No problems there.
Back to the 55. Same problem.
Then, and bear with me please, after some switching back and forth, trying different HDMI ports and screen settings. Suddenly the issue seems gone. I, at the moment, only get it in the scary movie car scene when the picture is on dynamic. The other modes are fine. I can no longer reproduce it.
Now back to exhibit 1. Now that the problem seems gone, if I pause that dark intermezzo between scenes, I see some squares on the screen. Light purple. You know, because this show wasn't shot in 4K and is from 2010 or something, the squares you get when you watch something with a lower quality (it's streamed through my 4K apple tv). It seems as if, when the issue was present, the TV was trying to fix it or something and was freaking out, was refreshing those areas continuously. Yet, mpeg remastering and well all enhancements were always turned off.
I cancelled the repair guy that was going to come tomorrow, since I can only create this at night when it's dark. It's invisible when there's daylight.
What does this sound like to you? I don't think it's apple TV (I hadn't changed any settings there, I did now, but that didn't fix it). It's not my receiver because bypassing it didn't help. I'm not sure why it's gone now. And where it came from. I had the problem two nights in a row just before today. It may, of course, return.
