when i was running the break in images, i noticed that on green and grey screens only there is a dark sort of flickering pixel present that is not there on the blue and red screens.

is this a dead pixel? is it bad when it's like this?

is there anything i can do about it to fix it?

since you are running a breakin dvd, the TV is new; so 1) did you buy it from a store that will exchange it? 2) if not, try running an animated movies or one of the other remedies people have suggested in this forum- search under dead pixel

i got it from Amazon (i had no choice though, the 42" 800u isnt sold in stores).

I also have to unmount it several times (which costs money) just so panasonic will look at it, so i really hope it goes away or i can fix it before they come out and possibly tell me based on color or position that they may not be able to fix it.

anyhow, could you enlughten me on "other remedies" people have used? i'll try as many as possible.

not sure why an animated movie is considered a solution though, but i can try setting on CN for a while stretched and see if that helps.....

First, what kind of TV do you have? I know some manufactures wont cover one or a few dead pixels. I had the same problem. I have a Panasonic, I had a few dead pixels (7 to be exact) I called them up and they sent a guy out to get my TV and they had him install a new panel. I haven't seen any since. I would first call where you got your TV from though. If you got it locally, I'm sure you can return it. I presume you just bought since you're running the break in DVD. Then if you get know where that way, call the Manufacture up.

as i said in my previous post it's a 42" 800u.

I am worried that while they may be able to reapir it regardless of what kind of dead pixel or location it is, that because it appears to be just one that they wont bother.

is replacing the panel alot of work and mangling of the TV? do they have to crack open the whole tv for that?

is there any other way to fix it and get this damn thing to go away?

if its flickering it might go away, try using the break in disc in a loop. animation for some reason works as well. if its one pixel panasonic might not cover it.

im assuming its new so try those 2 things, break in and animation.

you can also try jscreen fix some of it is free and some if is not.

well i was of course looping the break in disk anyway, thats how i found out which colored screens it was present on to begin with.

if animation works (not sure why?) then i suppose i could try leaving it on cartoon network stretched for a little bit (how long shoul it take if it's going to workat all?).

i looked into jscreen but it's a software program and i dont have any computer stuff hooked up to the TV.

I heard the same thing about animation but I heard it was the CGI type, like a Pixar movie that really works the best.

while it's harder to see during regular video viewing since green and grey is in alot of picture, the pixel is visible much of the time there too.

damnit, i really want to fix this so i dont have to go through the trouble of unmounting, I dont like my new tv being mangeled so.....

Well, My tv started off with one, then it went to 7 dead pixels, with a few more flickering. I don't know how much work it was to take the panel apart. The service man came to my house ,took my tv, then two weeks later he was back with it. Would of been back sooner, but a snowstorm took care of that..

the more its on break in period and or pixar animation the better.

is this a new new new set like less then 100 hrs?

leave it breaking in if it is. use break in settings (mid to tad higher contrast)

Do a search. This topic has been discussed, and solutions and suggestions posted, many many times.

if you could take the time to post that, surely you could make a helpful suggestion as well if you know about these other topics? that way it would be sure i wouldnt miss it by having to check multiple topics.

Try jscreenfix!!!!!
then try pixar movies.

If that doesn't work them don't worry about it. a 1080p has over 2 million pixels. One dead one is not bad and not noticable at normal viewing distance and if you like pixels with better carpet then do the right thing by the remote control hanger.

without a computer hooked up, i dont know how i would be able to use jscreenfix.

I also cannot tell if it's a stuck pixel or a dead pixel.

i mean, it only happens on green and grey screens....so does that mean it's a dead subpixel, or that it's merely stuck?

i dont own a pixar dvd surprisingly, but i guess i could pop vampire hunter d bloodlust or some anime to see if that would do.

Chad, please keep posting. I've been off AVS for a few weeks and come back to more delightful Chad posts. (absolutely no sarcasm intended)

Spin,

With a 42" display you are probably watching close enough on most occassions to see this particular pixel problem. In addition, since you know where it is, I can tell from a number of your posts in this thread that having it there is going to a continued source of frustration. Don't let anyone tell you to simply accept the situation; it's easy for them to say.

Panasonic will likely not help you, nor would any MFR. They all have dead pixel policies that state a certain number of dead/stuck pixels is "normal." That said, with properly applied jedi powers and a reasonable CSR, you can get the panel replaced.

Personally, I suggest you just pack it back up and return it to Amazon. When you get your replacement, fire up a break-in disc and inspect before mounting.

A pixar movie is not likely going to solve your problem. What you are looking for is any content, pixar or otherwise, that has multiple colors changing rapidly. The more colors the better and the faster the better. You are looking for a kind of fusion of strobe and kaleidoscope. I was trying to think if any such movies came to mind, but unfortunately I came up empty. Perhaps someone else can think of one. It's also important that the color strobing takes place in the portion of the screen that has the troubling pixel.

Finally, I've never run across a flickering pixel before and that makes it more troubling to me. It seems like it could be either an electrical issue with that one pixel when the control board tries to excite the gasses for a specific color, or a problem with that phosphor application itself.

Good luck and PM me if you need the customer service line for Amazon.

rwr what about that software that is win zip, that flashes alot i dont remember it off hand but some users would use it.

You can try thishttp://www.techspot.com/downloads/1802-undead-pixel.html

and/or this

Gus...I'm with you on that. There are actually a few good strobing programs for Mac and PC. Problem is, the OP cannot connect a PC :-(

I was thinking there might have been a very stroby scene in the original willy wonka, when they went into that tunnel. Maybe something in clockwork orange...I just have vague impressions of films with lots of strobing colors...probably because they damaged something in my brain.

animated movies and jscreenfix are the two most common remedies people have talked about....they are described above. can you borrow someone's laptop to try the jscreenfix?

i really dont know, anybody with a laptop that would actually give it to me, or a cable to boot (since you dont need a VGA or especially an HDMI cable to go with a laptop).

otherwise of course i would try the jscreenfix. even though it would seem to me if this was a stuck pixel it would be "on", rather than mostly off (flickering a little) on the certain color + grey.

have you given up on the idea of returning it to amazon. it is definitely a pain to take it down and pack/ship it, but it may be the most reliable solutions if amazon will take it back. all other fixes, even if you find a laptop/cable are unproven and don't always work.

just a thought.....

Can you see the dead pixel at your normal viewing distance?

Does the 800u have a USB port on it and does it allow you to view Jpgs??
If so, maybe try the break-in images at a very fast slide show interval.
That way it would flash the screen on and off repeatedly at a fast rate.

also, Pixar movies have worked for some. Contrary to what some might say.
Roman O reccommends them to his customers and some of them have had good luck with them.

The best thing would be like someone else asked, borrow someones laptop and run jscreenfix.
Do you have a PS3??
Maybe jscreenfix will run thru the PS3 browser??

You are right Pixar is the way to go :)

I really like the display otherwise, and amazon no longer has it in stock it seems (as i think it is being discontinued), so as it stands i have decided i want to own a 42800u, so i dont know if returning it is such a good idea (after all, it could come back with more than one dead pixel). I just want it fixed, i got it for a great price, and i do like the set for the most part.

but yes it's also a pain in the ass to return (which is why i did so much research to make sure that i liked it enough that i would likely decided to keep it no matter what and just opt to get it repaired if there was an issue).

i dont know if it has a USB port, but i think i already pointed out that i was using the SD Card, and thats how i discovered the darn thing at first to begin with by runing the burn in slide show, did you read that part?

Of course i tried to increase the intervals to as fast as possible, the vierra slide show interface only allows it to go so fast.

i havent thought about the PS3 browser idea, when i get it hooked up i actually might try that.

really i'll just be very happy if the contractor guy (whome is generally in my experience pretty lazy to really help you out if they dont absolutely have to) just replaces the panel with a 100% functioning one and doesnt give me any guff about "proper working paramters".

to make matters worse, unless i do manage to fix it on my own, i'll have to pay money to unmount and then remount it because the damn re[air man wont just help do it....that sucks.....

i've been using jscreenfix on mine... i turned the 5 second clip into a 3 hour avi and have it streaming through my xbox. so far no change in the dead/stuck pixels. i think im going to try undead pixel since you can strobe the pixel as low as 1ms.


spincut any idea when panasonic is coming out to look at you tv?

well...ya that is a tough spot to be in...good luck.

btw, since you have been on the forum long enough, i am sure you realize that unless you get lucky with strobes, jcsreenfix or other such procedure (hope you do), there is not much panny can do to repair dead/stuck pixels.

unfortunately, dead/stuck pixel(s) is a reality of the plasma (and lcd) technology and most of us will have to face it sooner or later....i think it hurts more if it happens to a new tv, just like a scratch on a new car.

please post your update.

hey, could hook me up with that AVI? it's formated to fill the whole screen right?

I mean, i have an xbox and my computer is on a network (i just dont use the media feature that much because it cant really detect most of my videos).

Yeah, the thing is i've NEVER had a dead pixel in my life. I'm typing this on a 20" widescreen i got from dell, no dead pixel, i've owned several LCD PC monitors in the past (not all from reputable brands either mind you), no dead pixels, i've had several notebooks in the past, no dead pixels. I bough a 40" sony XBR2 LCD tv before this, and while it had it share of mura issues (the reason i returned it), no dead pixels (and i would think as an LCD with apparently poor QA it would be more likely to have dead pixels), my nintendo DS, no dead pixels, my PSP no dead pixels.

well you get the idea, suffice it to say i've had plenty of devices in my time and i have never caught a dead pixel.

no sorry the file is 1GB in size. it would take forever to upload on my connection. however you can easily make your own with VirtualDub-MPEG2, the ntsc dvd file from jscreenfix and the xvid codec. just copy paste the 5 second loop over a bunch of times until you have two hours and then save it as a xvid file. mind you the video doesnt pulse the colors very fast and hasnt worked for me yet. thats why im going to try undead pixel since 3ms is better than the 20ms or so the jscreen runs at.


imo there should be no dead pixels on the premium lines of tv. a lot of lcd manufacturers have a zero pixel policy(at least over seas)... i dont see why panasonic cant do the same.

good question-- i think pio and most major plasma manufacturer consider a few dead/stuck pixel normal.

well let us hope this one won't break the trend and what nervx is suggesting (or an animated movie) does the job for you

ok so the guy just left, surprisngly he helped me take it off the mount, took the mount bracket off (it was just a few screws anyway, dont know what the big deal was from Panasonic).

He also seemed immediately ready to replace the panel, he even thought someone else already came out to verify this.

Whatever, better news for me right?

ANYHOO, he does all the work and replaces the panel, i'm very pleased, he even mentioned how he'd make sure to test it without back on expressely to make sure it was all working right first.

Well, guess what, now i have 2-4 dead pixels! and guess what else, he said "sorry man, cant help ya". Not sure what the point of testing it before we mounted, but suffice it to say he refused to put the old (and clearly in better shape) panel in, insisted that he had to take it with him "because it was faulty and had a dead pixel".

So anyhow, now i have a panel with 2 dead pixel at least and 2 other 'specs' that may or may not be dead pixels, i dont really know what they are.

This sucks. I mean, i'm please of Panasonics response but god damn if the guy at least allowed me the option to keep the better operating panel AT LEAST. Now i'm worse off than before, and Panasonic better do something to rectify it, since my better working panel is pretty much gone, and am now a victim of "policy", i better not get any guff form them about "we tried, and that's that", since that would mean they were fine with making me worse off than i was before.

The guy seemed like he wanted to help, so i'm just surprised at how insistant he was about taking the old panel with him and leaving me with the worser one, i just dont understand the point of this, at least leave me with the satisfaction of getting to "break even".

Wow, very interested. Maybe these will clear up?

hmph, i doubt it, the other one at least had some flickery life to it, these are DEAD.

and i dont know about the other two, it's almost like tinier pixels...could be specs of dirt aded due to the repair, which the guy was also a bit innefectual to do anything about. he did his job apparently, the fact that i was worse off didnt seem to affect him much aside from given me his sincerest condoleces as he took my panel with just theo ne dead pixel away.

the repiar guy was actually surprisingly nice and accepting of the problem (unexepctedly replacing the panel when i thought he wjust going to check it, and even doing what Panny said they wouldnt do and helping me unmount it), until he was done that is, then he basicaly said "you know, other people dont care that much about this stuff, just deal with it i think", that annoyed me a little, since he wouldnt at least allow me to "deal" with breaking even. seemdl ike he was a victim of a stupid policy and a time constraint to not at least "juggle panels for you" as he put to me.

i guess if the damn replacement panel had at least better QA for it then my original and worked like i had expected than my feedback would generally have been glowing.

I had a red pixel on my 85u for the first hundred hours and then it flickered for the next hundred hours. Now after 400 or more hours it's completely gone. Some of the plasmas seem to get better with time.

Yea I would say most that I have seen but its not the case always :(

i think when the pixel is "black" and thus dead it likely wont fix itself......at least the other one had some life in it and maybe over time it would have healed because of that.....so damn it all that i now have mutliple completely dead ones instead.
