Ive just bought brand new plasma panasonic st50 and i have bad pixel in centre of screen. Its kind a strange because:
on basic green its black
on red its normal
on blue normal
on white pink or flashing pink
on grey flashing
Is it dead pixel or will it get back to life?
Should i go and exchange tv for new?

p.s. i tried various pixel fixers.

It sounds like one of the subpixels (RBG) is faulty, which is why some colors work and others don't. Green would appear to be the defective one. If it bothers you (and especially since it's in the middle of the screen), I would try to switch it out for another panel.

Probably not. I had a Pioneer with such a pixel whose subpixel was dead out of the box, and no amount of coaxing would bring it back to life. If you haven't seen the color green since turning on the set, it is likely a manufacturing defective.

If it were in the center of the screen, I would definitely return it even in your case. It would be all I could think about whenever watching the panel and thus be very distracting.

Depends on where on the internet I got it. If they're going to come out, box it up for me, and take it back then I'd be a lot more willing to go that route. If I'm going to pay for shipping and then have to hope that they'll refund my shipping, send me a new TV, etc... eh, that would be more difficult.

I would think you should expect to not have dead pixels. But I don't run slides, so for all I know I have one or more myself that I'll probably never notice.

it used to be said by the people who sell plasmas that playing a very colourful Blu ray (like The Incredibles) can sometimes bring a dead or dying sub pixel to life

From my experience thats rare. Its common to have dead sub pixels out of the box , and once they flicker it implies the sub pixel is on the way out. Once they die they die. Ive heard people knocking on the glass and resurrecting them (tried that but didnt work)

Devestating to new owners but if you can't see it from your viewing distance after 6 months you deny it and lifes more important dilemmas take over. My kuros have a few dead sub pixles : id take that over the poor convergence and geometry of CRT anyday and certainly over the lifeless blacks of LCD. It was an agonising first few months but now i love my pioneer plasmas.

PS : ive tried all those pixel fixers and theyve never worked for me on any plasma . You dont watch test patterns all day . On normal viewing material id doubt youd see it from the lounge . You will overcome this !!smile.gif

^Yes, I managed to get 3 Kuros in all...one set had it, but since I knew where the dying subpixel was, I found myself distracted by it, even if I could barely make it out during some content from my sitting distance. It depends on your tolerance level and how much trouble you anticipate to face when returning it.

maybe I would not feel distracted but feeling that I paid so much for item with flaw makes me crazy. I boxed it again with my brother and I'm waiting for reply. should I take again plasma and not worry about pixels or LCD is more safe option?

Go Lcd and say goodbye to watching movies at night time with any material that has dark scenes

was being flippant. Meaning plasma blacks rule. Ive had LCD's and watching movies at night , especially movies with lots of dark scenes were horrible on LCD. Any technology can have dead pixels . But if its picture quality thats most important to you, Id stay with plasma
