I've demoed the P50 today for the 2nd time. As well as I have previously seen just about all the current Fujitsu models. The PQ, especially on the P50/30 is excellent, however I have seen to some degree on all the Fujitsu's an apparent color uniformity problem. On all sets I have viewed there is either pink hue in the corners and or edges. In addition some sets had the pink hue and a light greenish hue somewhere on the panel. These hues definitely bled thru when images that were being displayed were bright (example, sand on a beach, sky). The sales guy felt it was a combination of reflections and incorrect color decoder settings. He was able to dial it out somewhat through the menu however not to a satisfying level. When we brought up the white screen option (on the 42, 50 and 55) the hues were very apparent. I don't understand how a panel that costs so much can have what appears to me this consistent issue. I've read one post here of an owner describing the same problem but otherwise there is nothing but praise for this panel. This issue has me really hesitant from buying it (I really like it otherwise). I plan on watching a lot of hockey and don't want to see pink/green splotches on the ice. Maybe I've just seen by coincidence a few defective panels? Is this the norm for Fujitsu's? Do people just not notice this or care? I have to admit it was difficult to see especially on darker content. In comparison when we looked at the Sony XBR white screen it was almost perfectly uniform. Any owners care to comment?

Checked out 3 more Fujitsu panels today (I really want one!) and sure enough they all had non-pure white screens. The 50" even had several odd fingerprint type markings behind the screen. The dealer explained, that's why it's a demo! I'd love to hear from any Fujitsu owners who actually have uniform white across the entire panel. Or if anyone wants to comment on their panels uniformity that would be great. I figure if this is the norm across several manufacturers then maybe I'd just have to live with it to be a plasma owner.

When I got my P50/10, it too had pinkish hue on white screen in upper left corner. However, I never saw it bleed through during normal watching - and I did look. However, over time (16 months) the hue has diminished somewhat and still is not visible during normal viewing. Others have reported it also. Nobody really knows what it is. The tint could be worse "dynamic" mode or some of the other torch mode presets. Also, P50s tend to be "too red" which may be a factor also.

This is pretty much my experience too:


on a white screen you will see a pinkish hue in some areas but this should not be noticeable on a properly adjusted display for normal viewing material


Others have reported the horizontal line across the middle of the screen of Panny/Fujitsu 50" displays when viewing a white screen: again this should not be noticeable during normal viewing

What could cause a localized pinkish hue? I doubt it would be digital processing problems. Could it be a manufacturing quality control issue?


At first blush I would not expect a plasma screen to be susceptible to ambient magnetic fields (as CRTs are). Plasmas "fire" a pixel by setting up a charge between an address electrode and a display electrode. Would an ambient magnetic field create a slight charge leakage -- perhaps preferentially in the red phosphors?


An extermal field messes up a CRT's display by ever so slightly bending the electrons streaming from the cathode. There's no electron beam in a plasma, of course, but would an ambient field establish a slight charge in either the address or display wires?

Thanks for the responses. Ross, I agree with your points and don't understand how this problem exists on a plasma display. Funny thing is I recently got rid of my Sony RP-LCD due to a very similar non-uniformity issue. In this case it was thought to be poor alignment of the 3 LCD panels causing pink/green/blue hues on the screen. As far as the P50 goes the sales guy who was very knowledgeable spent quite some time trying to dial out the hue and had some success. But even after I felt as if I could notice tone differences (albeit subtle) in the areas that had the hue. I just don't know if I could live with a pricey panel (thats otherwise fantastic) if mine had this issue too.

I too would like to know if this is a problem with Panasonics also or just Fujitsu panels. I'm trying to decide on a new 50" plasma and my choices are Panny, Fuji and Sony XBR. If Fuji has this problem, but Panny plasmas don't I will probably go with the Panasonic.

I've had a Fujitsu P50/30 for about 3 months now and do not have either the fingerprint or lack of color uniformity. If I did, I've found that my dealer and Fujitsu are excellent in righting anything that is wrong. You can go to Fujitsu's web site and send them an email regarding this problem and see what they tell you.

The photon release is what generates the phosphor light not the electrons. So this is a cell address problem with reds being on a little more to taint the white. Has anyone tried the service menu reduction of red on the white screen?

This is not exclusively a panny/fujitsu problem. my pioneer 1000hdi had a pink bloom in all four corners and pink line thru the center of the screen. it was 90% correctible by adjusting the high and low red in the integrator menu. initially i found it very annoying, but after adjusting, i almost never notice it.


an interesting aside, pioneer customer servcie had a service tech out to my house within a day or two after my initial complaint. when his adjsutments did not hold pioneer wanted to come out and take the panel for repair/replacement. i told them not to bother, but to this day two months later they still call and ask if i'd like it taken back for servcie. impressive to me.

My Panny TH-37PA20 also has a very slight 'reddish' tint in the left upper corner of the set. In fact, I sent back the first example because the pinkish hue was quite pronounced and I knew after about two weeks that I could never be comfortable living with this. The replacement set, (the one I have now), also had the pinkish tint out of the box, but it was far less noticeable. It may have even diminished somewhat over time. Certainly the rest of the family does not comment on the tint, unlike the first set, which everyone noticed straight away.

Interesting that multiple different sets from different manufacturers using distinct glass and electronics exhibit the same type of problem.

Muniman,


When I bought my pio 1110HD, I was told by the dealer that if I found *anything* wrong with it (including stuck pixels) he would have someone at my house the next day to look at it. He said that a customer of his had a small blue streak in his pio (not sure which model) and it was completely replaced within two days.


My wife went over our display with a magnifying glass and couldn't find anything wrong...

I have a 42" Fujitsu and have a slight pink band at the top of the display. It is only noticeable on some regular programming, and even then it's just under certain circumstances. Not perfect, but not much I can see doing about it at this point. It seems to pop up about 1% of the time, if not less.

I've owned the P50/10 for almost a year -- checked the white screen out of the box -- it was pure white, no blooming at the edges/corners, nothing. And no "line" across the screen. And it remains that way -- i check it every couple weeks or so.


I'm in Boston area, watch Red Sox on high def cable and it's better than being at Fenway. Incredibly crisp, 3D, colors are right on. Couldn't be happier with the purchase. I see other plasmas -- poorly set up of course -- in the stores all the time -- none of them have the overall picture quality of the Fujitsu. It took me months to decide what tv to buy, this time last year, during a major renovation of our house.


Had a superbowl party, the picture was a knock out -- and sent a few couples home discussing getting a plasma -- nothing like causing marital stress. LOL.


Would buy it again, no doubt.


just my teo cents/experience

I've had two Panasonic 4UY plasmas. The first had a somewhat yellowish tinge in the center that was only visible when viewing a white screen, not in normal viewing circumstances. My current unit has, I think, the same thing to a very, very minor degree such that I have to really look for it on a white screen. But, again, it has no impact when viewing images on the plasma.

Spent a couple of hours going through the archives today and it turns out this issue with the P50 is pretty well documented. What puzzles me is that in my in-store viewing where ever I had seen a hue on white screen I was able to notice tone variations when video content was playing. Most people seem to be saying that it's not noticeable, but I disagree. Despite all of this, I'm so blown away by the PQ, I'm still considering the panel!
