The service menu does have some color wheel adjustment setting which I assume is the control needed. See a few posts up for instructions for gett by into the service menu.

Market for Mitsu HC-7900DW

I bought the HC7900DW with warm and fuzzy memories of my HC1500 I had bought years earlier. I replaced the 1500 with a Panny PT-AE2000U when I moved to a home with 8' ceilings in the basement and it worked well until I began to have problems with powering it up...the lamp ballast failed. So I replaced it with the 7900. It had an excellent picture and every feature a projector enthusiast could want, especially for $799 new, but I could never get the picture right, due to my low ceiling height. The inability to get the keystone issue cleared up to my satisfaction without doing a costly remodeling of my basement drove me crazy, so I sold it, replacing it with another Panny...a PT-AE7000U refurb for $870. The amazing thing is that I listed it on eBay for $870 and it sold within 5 minutes, so I made a $70 profit on a used unit with a little over 1000 hours on the lamp!!! I probably could have gotten $1K, had I asked for it. There is a market for this projector. I'm going to miss the bright, sharp images of the HC7900DW, but I needed better keystoning features. Sad to see it go.

I searched the last several pages of this thread for "service" and can't find anything about the service menu, does someone have a direct link to the post or the instructions themselves?

Thank you

It was post #1181 , just ~20 posts ago:

"reach the [service] menu by going to Settings - Language; Leave the cursor on your Language and, using the remote, press Auto Position, Enter, Auto Position."

Turning OFF Video Processor

I would like to try just the VP from the Onkyo 818 is there a way to disable it on the 7900? I have it turned OFF on the 818 as I found having both of them active degraded the picture, IMO.

My lamp is pushing over 4000 hours, so I figured I better order a new lamp. I bit the bullet and ordered a complete lamp/housing unit. Seems to be hard to shift threw refurbished crap and the real thing. A little cheaper but still pricey I went through projector people at $302. You put in the order through them and then it ships to you strait from Mitsubishi. Talk about fast shipping. Ordered Thursday afternoon and was delivered Tuesday morning. Now to milk the current lamp as long as I can before it pops.

That's fantastic!
Let us know how the new one is once installed!

Thanks!

Finally hit 5000 hours and projector auto shut off. Lamp was still working fine. I had to reset the lamp hours to be able to turn it back on. So now I'm still on the original lamp with over 5000 hours. I know I'm on borrowed time, but if it is still working I'm going to use it till it pops.

On my previous Sharp DT-510 I did that at least twice and got 300% of the lamp life (it was rated at 4500 hours and I got around 13500 hours). My 7900 is getting close to 5000 and it didn't even cross my mind to think of ordering a bulb as to me that means it's only 30% used assuming it lasts like my Sharp.
