The Official Pioneer 9G North American KRP-500M / KRP-600M Owner's Discussion Pt. II - Page 213

How many hours are on your 500M? Mine has almost 2000 hours. Have you activated the ISF modes on your display?

Actoin movies are normally watched on the 141FD due to the sound system it is paired with. Everything else is played on all three and the chosen display depends on mood.

Nice. I just didn't know which display was your favorite

I have 2346 hours on my 500m post KuroControl ISF reset - so probably about 3500-4000 total. No red tinted blacks. But I'm very, very careful with my set.

I don't remember the build date and it's not convenient for me to detach it from the wall/stand just to check, but if I find somewhere that I wrote it down I'll post back.

I think I started to notice the red tint during blacks a couple of months ago on my 500m. Makes me sad

Yep very sad. Looks like the famous Kuro has problems just like the rest of the displays. What MFR date is your display and how many hours are on it?

Checked mine this evening. I have a October 2008 build date. I probably have between 3-4,000 hours and no sign of red tint.

I don't think I have an Oct 2008 500m, but I do notice a slight red tint in my blacks in a dark environment with lots of blacks on screen. It's very slight, almost like an artifact of dithering.

Not exactly news...most, if not all, of the 9G sets suffer from DSE (dirty screen effect), surmised (once again) to likely be due to uneven application of the antireflective screen.

Yes but I think this reddish tint flaw is worse and is ranked up there with FBR and rising black levels...

I agree. It's on par with rising black levels. I too have the red tint problem on my 101fd that was manufactured april 2009. When I compare my red tinted 101fd side by side with my 111fd, its no contest. The 111fd now has the deeper black level. I hope there is a fix.

Depends how many people have it. As far as I can tell, there's only a few on these forums who've experienced it while the vast majority don't have it. That's called individual set defects. Rising black levels in Panasonics were by design.

Did you try contacting Pioneer and seeing if they can repair it? Off-hand a red tint seems like a problem in one of the boards... unless part of the panel itself is prematurely aging and getting warmer as a result of being out of sync with whatever adjustments are normally supposed to be made. Alternatively, if the board responsible for the adjustments is bad, that could explain it as well.

Could also check for bad capacitors.

Yes. I contacted pioneer, but they won't tell me anything because I'm having problems with my warranty. I need to sort some things out first. I'll update on what they find.

I contacted Pioneer and they were of no help and said they have never heard of the problem. Maybe they just don't have any documented cases so that is why. I know others have called in about it. My warranty is up also so that could be another reason why they weren't too helpful. I think they "searched" for previous cases of this and came up with nothing and then the lady told me a local repair place I should call. I never did call them though. Guess I should do that and see if they have heard of the problem.

I have also found a few other threads on other forums about this problem. There is one relating to a European model (lx5090). I am not sure if I can post a link to that forum but here it is (hopefully mods won't delete this as I think it is very important to the issue):

On another note do you guys think we should start a thread dedicated to this so that other Kuro owners besides 500M/600M owners might see this and contribute to it?

IMO, I think the whole DSE phenomenon is nothing more than a video processing artifact as people claim to see it on many displays from plasma to led led.

Put me in the never experienced it camp for a 5080, 500M and 600M.

Is this something that people actually see while watching content, or just when staring at a blank screen?

Yes it is mostly noticeable in the black bars in widescreen movies when you are watching in the complete darkness and the movie is kind of dark.

Yes Mac13, start a new thread. The more who get involved the faster we can get Pioneer to possibly do something, there is very good info in the link you provided, if they can fix it in Germany, they can fix it here. I'm still under warranty!

I'll try to find out when I get home.

Just a heads up but I started a dedicated thread dealing with the red tint issue. Any of you that have commented on it in this thread feel free to head over there and add your comments in and vote in the poll!

I too have the red tint issue, been on my set for about a year. I have the KRP-500M. I notice it when its dark in my room. I hope there's an easy solution as I still have yet to see a better display.....

Please go and vote in the poll on the thread I created dedicated to this issue

Hm now I have to see if I have this issue....Is this something blatantly visible, or is this something I have to search for in a dark shot?

I was looking at WOW Disney calibrating disc just last weekend, but I didn't notice anything odd.

You might want to read the other thread but usually this is hard to spot if there is any light in the room. You have to be watching in the complete darkness and it helps if you watch a movie with a dark scene and look at the bars at the top and bottom of the TV. You can also just put up a black screen and check but it needs to be completely dark to check for this.

Just to throw my 2 cents in, I have a KRP-600M purchased new in Aug 2009, and I have never observed any red tint. One other question: Does anyone know how this TV handles an incoming 720P signal via HDMI. I'm looking at an inexpensive converter from Cyberguys which takes either a composite, s-video or component input and scales the signal to 720p via its HDMi output? thanks.

I'm not sure what you're question is but the Kuro scaler is acceptable. Even on a 60" display you'd be hard pressed to distinguish a high quality 720p signal from 1080p. If you watch network television ABC and Fox broadcast HD in 720p.

It's a screen defect on my 6020..the same old light and dark horizontal bands in the same places. (they don't change location) Vertical pans on HGTV and other shows with a solid color background look bad. Not very noticeable on horizontal pans at all. My old Panny 60u showed no such issues on the same material. There is no doubt in my mind that the phosphors are not evenly bright over the screen area, and/or the AR coating is uneven and causing this effect. ChadB calibrated mine last year and said he didn't know what DSE was either, but after I pointed it out he got it. I really find it the most irritating flaw on my set. The reddish blacks can at least be totally avoided by keeping some room lighting on. Seems every set whether plasma or LCD has SOME issue.

Why not just let the tv do your upconverting? Or do you need you need inputs the tv does not offer? Or you could buy an AV receiver and run everything through it to your set via HDMI at native resolution and still let the tv do the conversion.

I haven't tried this converter yet. It's only $79 and has no picture controls of it own, so I'm not sure how effective it would be. In the meantime, I'm trying to get the best picture possible from the panel's composite input with my LD player using the "Movie" mode being calibrated with the LD version of Video Essentials; but here's the problem, there isn't any way to set the contrast using the disc, since it uses that "line bending" test pattern which was made to adjust a CRT display and not a plasma. And, to a certain extent, this also applies to the pluge pattern as well to adjust brightness. So, now I'm wanting to try the "Pure" picture mode, which has been professionally calibrated. Can I manually copy the settings from this mode, which is on one of the HDMI inputs, to the composite input without screwing something up? As far as I know, each picture mode, such as Pure or Standard, can be individually calibrated for each input, right? Any comments or suggestions? thanks!

I had it on my Panasonic G10. I could see it on plain white screens so it's not likely a video processing artifact. I don't have it on my 500M though, nor is it on my brother's 8G Kuro.
