I have a Sanyo PLV-1080HD I am getting sort of a pink color shift on the right side of the screen and yellow on the left. It’s a fairly new projector, less than 1 year old. Does anyone have any other causes in mind other than the polarizer? Sounds less likely for such a new projector.

I called Sanyo and talked to thier service dept. They had me turn my focus all the way in check for spots then focus all the way out. I was told if you see spots while focused all the way in and they disapear all the way out it is likely there is significant dust build up on the panels which can be cleaned and will solve the problem. I am going to try that... the polorizer sounds like alot of $$$$.

This is exactly my woe:-
Slight pink-magenta cast in the middle brightness range and a slight unevenness in the white field, with subtle additional magenta tinges in various areas of the image, unnoticeable on color material, though they are visible if you look for them very carefully . I tried different sources with HDMI and YCBCR. The result is the same. Different color modes like the HDMI wide and YCBCR 4-2-2, YCBCR 4.4.4, RGB and the auto modes were used to configure, but with same results.

What this could be due to?
I use a sony blu ray player, the BDP S 370 with an HDMI in-out and that's it. No loose ends anywhere. Power line stable.
The test signal used to check the whites was from the 'LIFE' series blu ray from BBC where it carries a HI DEF set up as an extra. The whites had the magenta at about three points, all of them in varying intensty, but is evident only on close scrutiny. With this information in mind when you go to watch any programme material you can identify the magenta there. But for someone who hasn't seen the white test this magenta may escape him.
Can you kindly throw some light please?
The projector is just 100 lamp hours old.

Did anyone get to the bottom of this?
I'm having the same issue with a magenta color shift on the right side of the screen on my Sanyo PLV-1080HD. My projector is a year & a half old & has 1600 hours on the bulb - I started noticing the color shift around 1550 hours. Since my projector was still under warranty, I sent it in to Sanyo a month ago & was told that the lamp was the culprit. I replaced the bulb a few weeks later only to find that the magenta color shift is still there.
I've tried calibrating & re-calibrating with my HD Basics Blu-Ray to no avail.
I just called up Sanyo again to let them know that the new lamp is producing the same results & felt some resistance to my claim on the other end... I don't want to have to send my projector in again & be told there's nothing wrong with it when there obviously is.
Along with DonS's report, I've read several other posts online about this issue popping up on the same model when the bulb is still below 500 hours of usage so the issue seems more widespread than they're making it out to be...

It's been about a year and a half since my post about color shift. cleaning the dust from the panels solved the problem. but I had to use compressed air instead of the little bulb they give you with the projector. If you try this be very carefull make sure your air is clean and dry if using a compressor. dont use the air in a can like from one of the office stores, it can freeze when discharged. I used air from a scuba bottle since I knew there would be no oil in the air and the air would be dry. It worked but next time I will take it to the repair shop and let them do it.
