Panasonic Plasma 4:3 Fade

I have a Panisonic 42PHD6UY that is a little over a year old, average about 2-3 hours/day. I have calibrated using AVIA. I was told by some reps at a reputable Home Theater store (not Best Buy) that I should not worry about displaying the image in 4:3 with black bars because it would take "forever" for any difference to show up. Well, the other night I did notice some brightness difference on the sides when viewing full screen. The difference is slight, my wife can't even see it, but it's now driving me crazy. When I first saw the sides, my stomach sank. I thought Panasonics were supposed to last forever (60,000 hours), and this difference is not "burn in" but "fade". (I'm assuming)

I have finally gotten used to the stretched mode, and now I'm wondering? Are the side pixels just over hyped because they're still sort of "new", I've heard with some TV's that the new pixels will burn extra bright for their first 100 hours or so. Will they eventually catch up with the center pixels? Or has the center faded that much and I'm in for a disappointment?

Any help would be great. Thanks

Hey Andrew. My Sony came with a screensaver mode that turned the whole screen white which fixed that problem for me. If you are "semi computer savy" you can make a VCD that is 100% white and display that on the screen for about 5-10 minutes. That will warm uo all of the pixels on the display and it will look like azn even picture. Are you stretching with the TV or the box? If you set the box to 480i your picture will look much better too.

Thanks Cuylar Blair! I'm somewhat computer savy, but I've never made a VCD. If you could give me a few tips, I'm sure I could figure that out.

It sounds like your saying that the center has not necessarily faded, but that the side pixels just haven't warmed up? Is this correct? Meaning, a completely white picture for 5-10 minutes will even it out, not just fade everything equally leaving the same problem, only a little dimmer all around?

I'm stretching using the TV. Panasonic calls it "Just" mode, where it stretches the edges and leaves the middle the same so that it doesn't distort everything. I believe I have my comcast box set to 720p or 1080i.

Thanks again for your help

Pretty much.

Here's the basics. Make a picture in ms paint that is 160 x 90.

I used Adobe Premiere Pro 1.5 but you can use MS movie maker. Its like making a slide show but the only important thing is that it will fill your whole screen.

Use Nero, EZ CD Creator or something like that to burn the CD.

Let me know if you have too many problems and I'll just e-mail you a CD image.

Thanks. I'll look into it.

Silly question, would watching 4:3 picture with the side bars turned to the highest white possible for 5-10 minutes do the same, or is the idea to have the same exact color all across the board?

You are trying to even out the picture.... if you just do the sides it will look like you cut a picture in thirds and taped it back together. you will still see the lines.

Good point!

Just to clarify....Playing the white screen will even out the picture. It's not just an accelerated fade? Just want to be very careful.

Well look at it this way..... When you look VERY close to the screen you will see little red, green, and blue lines.... They are always being used... this is JUST like a tube TV. In the world of color RED + GREEN + BLUE = WHITE. So that being the case you would use a white screen to use all of the "bulbs". Don't worry about the fade. My uncle has a 3 yr old that still isn't faded. You don't have anything to worry about.

Cuylar Blair,

I'm revisiting this post, hopefully you'll get it. Could you possibly send me the CD file to (llcamino@hotmail.com)? I'm just running low on spare time to figure it out. Also, I just noticed you said to turn the box to 480i for a better picture. I've seen lots of debates about 720p vs 1080i and people go back and forth on that and ultimately say there's not much of a difference. However, I understood 480i to be the lowest quality. Am I missing the point on this? Did I mention that I am using an HD monitor, not ED.

Thanks for your help.
