Looking to upgrade my old Mits 1080i 55" CRT RPTV to a much bigger screen, and thinking of picking up a used 73" Mits DLP as a stop gap for about a year or so(not wanting to buy UHD TV until the new Ultra HD Blu-ray players and discs are available). There are actually quite a few used 2010 and 2011 units available on CL, but I have not seen many 2012 models.

I've done a fair amount of reading on these sets and I have not had much success in determining whether Mits actually improved the image quality significantly from 2010 to 2012 models. Did they upgrade the chip, lamps, screen technology? Also, within a model year, is there any difference in picture quality between the 6XX, 7XX, or 8XX series? I don't think I care much about 3D capability or wi-fi.

If there is not that much difference in image quality, perhaps I should just go for a 2011 or 2010 unit. I have seen 2010 73" units for for around $500! Besides picture quality, any other factors that should play into my decision? Thanks!

They generally got better as they got newer, but Caveat Emptor: from about 2007 to 2010 (so far), they used some DMD chips (it's the mirrors) from TI that have a known track record for failing early. Check any set you consider buying for stuck pixels. The DMD chip is around $200 from shopjimmy.com and there are youtube videos showing how to replace it.

You can still compare 6XX, 7XX, and 8XX series on Mits' website. http://www.mitsubishi-tv.com/support/documents

Thanks for that info and links! Yeah, I think I will focus on a 2011 or 2012 model. From those links, it does not look like there will be much difference in picture quality between the 642, 742, and 842 series. The only difference I can find is that the 842 has "PerfectColor" and "PerfectTint". Not sure how much difference that makes.
