Note that a quick remedy for IR is simply to display an all-white test pattern, rather than to run a white wash function.

for what it's worth, im using DPT via my htpc and run all colors ..

but as ive posted above, i really dont use it.
youre right bro, dapat talaga tawag dyan "burn-all" ..

The cheaper model UPS are usually just line interactive - meaning if there's no problem with the commercial power, it is on bypass mode and just sends to the device whatever the supply is .... there's no voltage regulation ... another thing is that the output is not a pure sine wave - but this is good enough for devices not using AC motors.

The more expensive UPS uses double conversion - converts AC input to DC, then converts it back to AC ... the process offers clean regulated power to the devices connected ... there's more circuitry, hence more expensive.

Thanks raptor! Didn't know that. When you say AC motors, you mean devices with actual motors like refrigerators?

@barrister

Cool info! How about going to a no channel area that displays a white snow like pattern? Would that be fine?

Yes, that would be a safe and simple method.

Sir ninjababez' Dead Pixel Tester utility is also good (Dead Pixel Buddy is another alternative). But if you don't have an HTPC connected to the TV, or if connecting a laptop would be too much trouble, try the plasma break-in disc:

http://www.eaprogramming.com/downloads/download_main.htm

From the author:

It is basically a set of 20 images that are 720p native resolution. The images are full screen colors so that the entire screen is 1 color at a time. The colors go from a white to a dark grey in 5 gradients, white to blue in 5 gradients, white to green in 5 gradients and white to red in five gradients.

You can set the DVD player to play a loop of only the white image.

thanks bro! im actually looking for those, i mean that particular site/page, cause i know someone who wants/needs it.
i think it was you who posted that before (another thread), but i was too lazy to checkout all my bookmarks page ..

Yes, i was the one who first posted it. But that was posted so long ago that it would be extremely difficult to search for it now.

Thank you will download the program and repeat the whole "burn-in" test.

Anyway ano po ba plasma nila sir?

Thanks.

yeah ive proven this already .. but panasonic doesnt have the white wash option
btw i never timed doing a manual "whitewash" before, but i think its under 30minutes .. if i have time ill try and time it this weekend ..

panasonic plasma has anti image retention - scrolling bar option, is this the same as white wash option?

Panasonic Viera 42PA60M, 42" EDTV 9th gen.

It's the last of its kind. Panasonic does not make EDTV 480p consumer plasmas anymore.

No. Panasonic's White Bar Scroll is for image retention (residual charge in the plasma cell). White Wash is for burn-in (uneven phosphor burn).

A White Bar Scroll functions as a screen conditioner, similar to a CRT's automatic degausser.

Creath.net (not a Panasonic site) says:

"White Bar Scroll" sends a wide, vertical, white bar scrolling across the screen. This area of even brightness theoretically wipes away temporary burn in. It appears to work. If the panel is truly burned in from long periods of misuse, the white bar scroll won't help.

Sir,

Yes - equipment like refrigerators ... large laser printers (e.g. Meralco bill printers) and mainframe computers also uses AC motors, hence they would specify online UPS with pure sine wave output.

Ano ang scrolling bar option? Is this a feature I can access through the menu of the tv? Saan ito sa py850?

...simply because, current Panasonic plasma panels have no permanent IR problem so there is no need to have the white wash option.

yeah i agree, its just that i was used to having this function

by the way 6 hours of playing ninja gaiden sigma (ps3) a little over 10 minutes white wash*all white background via htpc*(i took a quick shower so it could be under 10minutes )

I have a plasma question though. Has anyone noticed those diagonal criss-cross patterns on the screen? Parang steelwire fence yung pattern. xxx I have a pv8.

Here's what I'm talking about:

I'm not sure if it's a pattern created by the pixels (phosphors?) or somethng else altogether. I only see it if the room is bright and there is no picture on the screen. It's also slightly visible in dark scenes.

hi bro, i never experienced that before.
can you send me a clip or something that could produce that so i can try it out?
is that a movie or a video game?

sardaukar · « **Reply #77 on:** Feb 19, 2009 at 07:32 AM »

That's just set to hdmi 2 but with no source. It's also there if it's off. But I think kailangan ng light source behind you (in front of the TV). Sa akin kasi bintana yun at may blinds lang. That's partly what you can make out also on the screen.

young_Miklo · « **Reply #78 on:** Feb 19, 2009 at 09:34 AM »

^^^ i also get that from my PV8. bka normal lang yan.

verde9 · « **Reply #79 on:** Feb 19, 2009 at 09:42 AM »

I also have a PV8 but I don't see that "chicken wire" like image on my screen... usually if it has no source is in deep black.
hmmm...I'll check again the other sources later.

ninjababez® · « **Reply #80 on:** Feb 19, 2009 at 09:58 AM »

i thought it was a reflection mo my 3rd floor gate.

ill double check later

sardaukar · « **Reply #81 on:** Feb 19, 2009 at 11:56 AM »

@young_Miklo

Sana.

@verde9

Maybe because you don't have a bright light source across from your TV? Anyway good if you don't have it. I just hope it's normal that mine has it.

@ninjababez

Will wait on that.

yeah mine too but i remembered seeing that in my pv80 before.
i just dont know how to trigger it again since ive already treated the lighting of my living room

Carlo777 · « **Reply #83 on:** Feb 19, 2009 at 12:32 PM »

Hmmm...saw your pic yesterday and checked my units, it does not have that.

kakashi · « **Reply #84 on:** Feb 19, 2009 at 01:07 PM »

mine too, ive been staring at my pv8 since i saw the pic you posted, and i couldnt see anything like that...

hmmm, how old is the set with the chicken wire image?

sardaukar · « **Reply #85 on:** Feb 19, 2009 at 01:14 PM »

Hehe para bang naging hidden 3d image.

It's fairly new. Bought just this year. When you guys are checking, is the room fairly bright? Cause I also don't see it if the room is dark.

Checked on both a bright surrounding and a dark one still don't see it.

Carlo777 · « **Reply #87 on:** Feb 19, 2009 at 01:25 PM »

POST UPDATE:

YEAH! I can see it already on my PV8, I'll go down lang to check it sa PV80 (Nasa kids room kasi yung PV8). Bright surrounding on a blank HDMI input, grabe pati yun nakikita nyo

I'll also check the PY800.
