Panasonic Plasma Issue
So I've got a Panasonic Plasma that is about 16 months old. It's my second Panasonic plasma and up until now I have been nothing but happy with it. I've tweaked it to a tee and overall the image is absolutely stunning.
But the other night I saw a "grid" on the screen. Especially when the screen is a lot of a solid color, like white with snow, or green with grass, etc. Four bars vertically and 2 bars horizontal. Evenly spaced. Like so (quick PS job)...
Any ideas? I assume it's either the backlight or some power system back there?
Now I do have an entirely new HT setup these days. So I tested different cables, with or without going through the receiver, different sources, etc. Same thing.
And I'm probably four months past the warranty... :/

Let me clarify, the screen isn't stuck on a solid green screen. I just did that for reference as when I put a solid color on the screen, the lines are most obvious.
In normal viewing when there isn't a lot of solid colors, you can't even see the lines. I can I guess but most people wouldn't.

I suspect either the display panel or the control board is bad.
Unless you had something like a video game that was producing that grids for a long time, that is not burn-in. You could try running an all white screen for a few hours to see if it will help but I doubt it.
Plasmas don't have a back light.

I've tried the anti-burn in app the TV comes with for 30-45 minutes and it did nothing. And I agree, there is nothing I put on the screen, especially for that length of time, that would make such a burn in.
I figured it was some kind of power board. But I'm not sure why a failing power board would affect the screen in such a way.
I just got off the support chat with Panasonic, which was all but useless, and have a self-check procedure to go through.
I'm not happy.

I tried every HDMI input, multiple HDMI cables, component cables, different sources, receiver no receiver.
Last night I tried the hidden "factory reset". No bueno.
However the factory reset did, in fact, reset everything. And upon viewing after the reset the lines became less obvious. So I played with the video settings and the temperature does affect it a lot. But I have to use a setting I don't like.
I'll call their support tonight and see about service. I wouldn't even be opposed to cracking the TV open myself and replacing a logic board or what not if need be. If I knew exactly what it was that needs replaced.
It would suck not having a TV Sunday. 40+ people at my house. Lol

I thought I'd post an update about this...
Oddly enough, it went away. Lol... I have no idea but I'll take it.
