Have you had dead pixels on a Plasma or LCD TV that you owned?

[mterzich]

I am interested on determining the frequency of dead pixels on Plasma and LCD TVs.

[westa6969]

LCD FP's cannot get dead pixels by nature of the backlight technology. On rare occasions a stuck pixel can occur but no dead ones. I have 4 in my home with ZERO and over 200 on my network with ZERO. :)

Isn't a stuck pixel the same as a dead pixel?

[gsmollin]

It's the same in that it failed. I suppose a dead pixel would be stuck-at-black, and a stuck pixel would be stuck-at-a-color.

Anyway, I have had 5, and 1 had a stuck-at-red pixel.

I don't want to be to harsh, but most of you are in a fantasy world, and don't know what to look for!

Thanks to this forum, I've both found this wonderful Panny 50" 8UK, and a dead blue pixel(1) at the same time!

Don't fool yourself, that if you find 1,2, or 3,dead/stuck pixels that Panasonic will do anything, or your E-retailer about it, cause they won't!

I bought my PDP from one of the Auth Panasonic "dealers", and the sales manager told me that Panasonic wouldn't do anything about it,(any dead/stuck)pixel, but I tried!

The head field rep had me go into the service menu, and it has a signal generator that gives you all 3 color screens(RGB)(full screens of each color) to check for other dead/stuck pixels, plus I sent him a digital close up of the dead pixel.

After all the effort, to rectify the problem, he tells me that it is within Panasonic's guidelines.

The bottom line is this monitor is still the most spectacular Screen I've seen, and if you view it at a normal viewing distance, you won' see 1,2,or 3 tiny little black specks :cool:

This should be the only problem I have with this tv for what I've spent!

Don't be a nit picker!

No dead ones , just a single stuck one

If you have a PC connected to your FP, you can use Dead Pixel Buddy to check you screen. You can down load it from the following link.

mterzich, I don't know what you are going to prove with this survey, but I know what a bad pixel looks like and so does the Panny tech! So thanks for the download, but not needed!

If you look in the owners manual of the 8uk, and I assume the consumer models they cover themselves by saying in so many words that if part of the screen doesn't lite up, that it's normal and not a defect! :eek:

Westa6969, btw, as far as the Panasonic rep was concerned, about bad/stuck/dead pixels, he said that lcd's where the most common, and would continue to do so with age, but not plasma screens.

I'm not trying to prove anything. I just used your quote to indicate to people that they can use Dead Pixel Buddy to find bad pixels if they didn't know how to find them (but I had already assume that most knew how to find a bad one).

[QUOTE=mterzich]Isn't a stuck pixel the same as a dead pixel?[/QUOTE]

a stuck pixel is one that is stuck on all the time: a dead pixel is one that does not light up at all

Obviously a stuck pixel can be more noticeable and bothersome than a dead pixel

some posts deleted

calm down folks :)

[doubleroll]

I have a Plasma and a LCD and no pixel issues. It is very easy to see any pixel issue, stuck or dead, if you use a white screen...However, in the medical imaging field we use LCD flat panel monitors and I have seen pixel issues occasionally.

I think this is a valid survey, what's with all the hostility?

No harm in giving the program a run if you can hook you PC to your set. I tried it on my Digimate 37" LCD and after running throught the 5 solid colors it displays I found no stuck or dead pixels on my display. None on my laptop either :D

[mterzich]

I think everyone knows that these polls can be very inacurate (only one out of six that viewed the thread responded) but what has suprised me is that approximately one in four LCD respondents have indicated that they had bad pixels. Although I don't consider bad pixels to be a big deal, it would be interesting to know if bad pixels are more prevelent with some panels (although it is difficult to determine who manufactured a panel for a TV).

[SingleAction]

doubleroll;

I didn't mean to cause any hostility about this thread(dead pixels), but knowing they are there, and not seeing them from a normal viewing distance, is a little too much information,and unnecessary to the general enjoyment of watching a tv,( I wish I didn't know it was there, cause I look for it now) and for the most part, nothing can be done about it anyway.

Kevin W, In my case, if you read my first post, the 8uk has the ability to do the same as the Dead Pixel Buddy, so that's why I said it wasn't needed.

So my advice to everyone else who is happy with there plasma/lcd display, if your happy with it, once again don't drive yourself crazy finding something you didn't know you had, didn't see, and enjoy! I think it's more common then you think!

[Chris_006]

I had 2 on my 7" LCD in my vehicle that I bought 5 years ago, and recently I noticed that 1 reverted to working condition.

Suprised it still works after 5 winters in -20 degree weather. :)

None on my 32" LCD.

I agree that there is no way a survey here can be "accurate"... but I also think there must be a fair amount of pixel roblems or the manufacturers wouldn't try to pass it off as "within specifications". If affected panels are so rare, you'd think they'd just just stand by their product and replace them.... speaking as one of those with a rare dead pixel easily viewable from 10 feet.

[42Plasmaman]

I have a Philips 42PF7320A/37 Plasma TV and just noticed a stuck pixel near the middle of the screen. The TV is about a month old.
The pixel is purplish/pink in color when the screen is white.
Otherwise, I don't really notice it but I know it's there since I found it.

Is there anything that can be done for stuck pixels ?

[revmike]

Well for my money ignorance is bliss. I don't look for them because I know that if I did find one I would be concentrating on just that area and could not enjoy the picture.

[optivity]

(1) TH-50PX50U & (1) FPD2185W with (0) de d/st[color=red]u[/color]ck pixels.

[size=1]at least none that I've noticed[/size]

[dano1122]

sony 32xbr lcd, pixel stuck red near center, exchanged for 40xbr no stuck/dead pixels (that i've noticed thus far). though lcd sucks for color reproduction so i may take it back for a plasma.

I'm in the process of getting an RMA for my 37PHD8UK right now. It has one malfunctioning pixel very close to the center of the screen that goes dark whenever it tries to display a color approaching white. It's quite noticeable watching hockey games, for instance. The screen also has FOUR malfunctioning blue pixels, but these are much harder to see, as they only go dark when displaying a pure bluish color. If it weren't for the one bad green pixel, I'd be happy to keep the unit.

Anyway, I don't want to jinx myself, because Panasonic hasn't issued the RMA yet, but it doesn't look like it's going to be a problem. I think the size of the e-tailer and their relationship with the manufacturer has a lot to do with how easily you can exchange an imperfect display. I ordered through AVdeals, for what it's worth, and they are handling the whole thing for me.

[tgshoe]

I have a Pioneer PDP-42A3HD plasma display I have had for about a week. It has one cell stuck on blue right in the middle of the screen. Other than that the picture is great. Although I plan to have the picture calibrated. The stuck pixel is absolutely not noticed during normal viewing. It is only evident on solid red or white screens.

[cyberock]

is there a way to cause more pixels to go out?

I bought a portable dvd player from Best Buy with an extended warranty. I have one pixel which is out now and is very annoying on such a small screen. Best Buy refuses to service it until 5 to 7 pixels have gone out.
