Seems like this was caused by a bad lamp?

Got a problem with a projector? A DLP or LCD projector can have common issues. Why don't you check this forum out before running out to buy a brand new projector?

Seems like this was caused by a bad lamp?

I've got a 10 year old Mitsubishi HC1500 that developed a loud whine at start up which would quiet down after a few minutes.... I tore it down and found the color wheel had been rubbing on the exit window mounting screw on the mounting bracket - see attached png. The aperture and and bracket show signs of serious overheating! It looks like the lamp was focussed on the aperture plate (top middle and caused overheating and deformation of the color wheel bracket?! I had replaced this lamp in August of 2012 with what I thought was a OEM lamp... I would attach a pic of the box label (which I keep the old original lamp in) but I'm apparently over the quota; maybe I can add in a follow up post.

Seems like this is not really a very active forum? Too bad, it looks pretty organized, but it took me a month to get access and now I can't add attachments and while I'm seeing some views, I'm not getting much of a response (but then that's possibly because no one can see what I'm asking about)?
