*PN50B650 Screen-Fit issue.

by BestBuy Tech / July 9, 2009 12:27 AM PDT

When in the P.Size mode of Screen-Fit (not to be confused with Wide-Fit). As I moved the screen up and to the left, I could clearly see one whitish colored flickering pixel in the lowest right hand corner of the screen.

When moving the screen completely around in Screen-Fit (up/down left/right), It cannot be seen in any other corner. I also find it strange that this whitish flickering pixel is moving with the screen. Could someone else here check this out on there set and report back. I'd like to know if this is considered normal?

You need to be on a HD channel (like Comcast) to move Screen-Fit around. If not, you will on get the zoom function. This issue cannot be seen while in zoom or on a SD (Standard Definition) channel. A HD source is needed.

BestBuy Tech,

Do you see it in the Scrolling Menu as well, or just with the Comcast box?

I could not see it anymore when I switched over to the scrolling menu for the screen burn-in protection. I also remember that the on-screen menu covered over it (like dark window tint), but you could tell it was underneith it by its lighter shade.

On this particular program, when Screen-Fit was selected (the picture got slightly smaller on all four sides) and you could see those long-white flickering broadcast scan lines above the picture. It was also a letterbox program. It's then when I moved the screen up to cover the long white flickering lines I noticed it in the lower right hand corner. Puttting it in 16x9 mode filled the screen and got rid of it, but still, I thought this was unusual and wanted to know if it was a dead or stuck on white pixel. I can't seem to duplicate it at the moment, as nothing in HD is currently playing in letterbox format. As of now it's gone.

If this was pixel related would it have moved around with the screen as it did when i moved the screen, and would it have beeen invisiable as it was when I ran the scrolling bar burn in protection?

Thanks..

BestBuy Tech,

A physical pixel would have likely shown up in the scrolling menu, which is why I wanted to isolate the input and see if it was happening when an internal feed was running through it.

Unlike LCDs, plasma pixels that get stuck generally don't get "unstuck" by using some of the conventional methods - in that once they're there, they're always there. So for now, I think it's safe to deduct that the panel and electronics behind the panel are working, and that the issue is somewhat isolated to the input.

Keep me posted.
