How did you find this projector new a year ago, it came out in 2009? I've had mine for over 4 years.
I feel like such an idiot. It was the lens after all. It wasn't dust though it was some kind of film on it maybe from using the fireplace else I don't know what or how it got there. I had to take it off the ceiling mount to see it. I used a microfiber cloth to clean it and the glow was gone. Thanks to all for your help.
Right now, I'm looking to get either a gently used Mitsubishi Hc3800 with 700 hours of viewing time at around $350
a new BenQ W770ST at $500.
I know that the Hc3800 was a much higher end product at the time of its release, but considering all the advances in technologies in the past 5 years, which would be a better deal? Also, lack of 3D is not an issue for me at all. I'll be viewing art house movies on Blu Ray.
Thanks in advance for the replies!
At one point there was a promo which provided a new bulb for free. You might ask if the previous owner took advantage of it, which might explain the low hours.
Make sure the firmware in the 3800 is up to date. The initial release had a tendency to shut down the projector when it received a signal it didn't like.
I have no experience with the BenQ, so can't comment there.

Where can I buy a factory replacement bulb, or bulb with housing, that is a reputable source and offers a fair price?
They also have good info on how to spot fake lamps http://www.projectorlampexperts.com/...tYourself.aspx
Thank you for the info, that's very helpful! I appreciate you taking the time to address my questions. I have a follow up question. What's the difference between the bulb that you recommended for $250 and the ones sold on Amazon for around $80? There are multiple postings like this one on Amazon, and I'm wondering if these are just sub-standard, non-OEM bulbs, regardless of what the advertisements say on Amazon?
I tried to post a URL to the bulbs I was finding on Amazon, but I'm not allowed to use URL's in this forum because I'm still a newbie. However, if you go to Amazon.com and search for "HC3800 lamp" you will find them quickly.

I have tried several OEM "equivalents" over the years and the VERY BEST outcome I had was 1/2 the life for 1/2 the price life. Yep, I have tried these "deals" and NEVER would I do it again. Buy the OEM or nothing at all.
FYI, OEM retailers list was on the Mitsubishi web site as of about 4 months ago when I needed a new Lamp. BTW: A "BULB" is the the light part inside. A "LAMP" is the light part PLUS the housing.
Ok, so in the least I'm going to buy an OEM bulb, got it. Can I save considerable money by replacing the bulb in my existing housing, versus buying a whole new lamp? I found these instructions on how to replace the bulb in the housing, so I could just buy an OEM bulb (from a reputable dealer), and replace it. Any advice on that approach?
I know $300 is a hard pill, but it is the only sure way to not get crap. I think bulbs are like cell phones nowadays where there is so much counterfeiting and outright lying. You take a gamble. Btw, I purchased my OEM bulb (Osram 230/0.8 E20.8 / BULB15 Factory Original Replacement Bulb Only) from Electrified on Amazon Feb 2013. I bought my OEM Lamp (complete assembly) in June from Projector People.
And in case you're wondering why I have had so many lamp replacements... These include friends' displays in addition to mine. From now on I tell them to just spend the money and buy the OEM Lamp. Then I don't get calls from them with issues afterwords.
Sry my english.
I have finger prints all over my image, but visible only when the picture goes all black. No idea where / how I did that when I changed the lamp - I wore nitrile gloves. Gotta get up there and see....
I've also read some people suggest using a vacuum cleaner (sucking air, not blowing it). Haven't tried that yet, but I may try that after leaving the projector on high one more day today.
Are you having a problem with dust blobs showing up on the screen or are you trying to figure out how to do preventative maintenance? If you've got dust blobs, then I've tried running the projector on high nonstop for several days and when that didn't work, I tried vacuuming every crack, crevice, crease, and orifice that I could find without totally disassembling the projector. So far, no dice. I see a service manual online that I may be able to purchase for $10, and I'm considering trying that. I'm also considering finding a trustworthy repair shop if the disassembly seems too daunting, or perhaps even buying a used/refurb from Amazon or eBay (but of course, how do I know I won't get a unit that is already in worse shape -- perhaps dust, perhaps that nasty shutdown problem I was lucky enough to not run into). If you're in the same boat as me, please let me know what you've tried and I'll report back my results as well.
Anyway, I have no knowledge of the legality of sharing this type of thing -- not sure that this place that charged me $10 actually has any distribution rights, so perhaps they had no right to sell it to me and I shouldn't have a copy of it in the first place. Or perhaps they're just hoping a few idiots will pay them $10 for something that ought to be freely available. Anyway, if it's *legal* for me to do so, I would be willing to share the service manual with anyone who needs it. I'll have to defer to wiser posters on whether it is in fact legal or not.
