This issue has been discussed in many different Pioneer model threads but I thought it would be a good idea to make a dedicated thread for this issue so that everyone would be aware of it and we can have a common area to discuss the issue. I will try and sum up what the issue is but everyone else please add your thoughts and personal experiences with this.
I have a 500M and recently noticed while watching a widescreen movie that the black bars have a reddish tint to them. It is most noticeable when watching in the complete darkness and while watching a dark movie like Harry Potter and the Half Blood Prince. I switched to a completely black screen and noticed that the whole screen has a reddish tint but it seems to be worse on the right side and especially the upper right corner. I thought this might be a source issue so I have checked with multiple PS3s connected through my receiver and directly to the TV as well as while watching Cable tv. The red tint is noticeable in all situations. I have tried messing with the controls but nothing seems to help. I think I remember a couple calibrators saying that they have come across this a few times but they were unable to calibrate the reddish tint out. I had a previously had a 5020 that had a brownish/yellow tint to the whites and I had it calibrated by D-Nice and he fixed that issue but I think that was related to the color temp being too low and is non related.
I have seen references to this issue in many different threads and forums. It appears that several people with the European LX5090 are having this issue as well. It is discussed in the following thread (hopefully mods won't delete this as I think it is very important to the issue):http://www.avforums.com/forums/pione...nt-blacks.html
It appears that someone on a German forum might have come across a solution but I couldn't find any further details about what they said the solution was ("The guy said that they set the panel to zero, put in new software and calibrated the panel again." -tapmeester)
I don't understand what setting the panel to zero means and I don't know what kind of software they might have put on there but to me it seems like this issue has to do with a hardware/panel problem and that would have to be replaced. It would be awesome if it was a software issue that could be fixed but I don't see that being the case and if it was, it wouldn't make sense why only some sets would have this issue.
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.
My 500M has a manufacture date of October 2008 and it has approximately 2800 hours on it.All Kuro owners please post what display you have and if you have experienced this issue. Also please let us know if you have any information that might help us find a solution to this. Again, to see the reddish tint you will probably have to watch the TV in the complete dark and might even have to watch a dark movie because otherwise the brightness from the film may mess with your eyes and make it harder to see the reddish tint on the black bars.
Hopefully we can get to the bottom of this and just maybe there is a solution!
