So I have a couple questions I'm hoping someone can guide me on. I've had my projector for a couple years, bulb finally went out, I cheaped out, got lucky once and not so lucky the second time, when 2 cheapos I bought exploded.
Finally got a legit BenQ direct from factory replacement bulb. I now have an ultra bright spot, almost like a dead pixel, but I am hoping it's dust or glass. The previous exploding bulbs were contained by the housing, but some glass has made it ms way into the projector. I have included a link to show what I'm referring to.
I also have a, well it's a bit like a dark cloudy spot about 4in in diameter. Barely noticeable and I couldn't capture it on camera.
Is this more likely dust? Glass? I assume if so that I could clean it. Or is it something more nefarious?
My other question is my elite screen is a 160" motorized variant. Sometimes the screen doesn't want to come down. The led indicator shows red, and the housing makes a clicking sound like it wants to engage, but doesn't. Then randomly thirty seconds to a minute later it'll come down about 50% of the time. Any chance this is just a fuse or is there a greater likelihood that I'll have to have it serviced?

I've heard some people saying that some projectors, including the one I have, the BenQ W1070, will start shutting down after 2 months or a bit more, due to overheating. In my opinion the overheating must be related to dust buildup inside the projector, leading to reduced airflow, even though I'm not sure that's enough dust buildup in 2 months. Since most of the DLP projectors doesn't have any filter, what should be done to prevent this from happening? Maybe vacuuming the air vents would help?
The BenQ W1070 have a sealed optical block?
I've also heard about dust getting inside the light path or lens after some time of use, is this a common issue?

A few days ago, a static rainbow colored "blotch" appeared in the upper left corner of the projected image. Today it turned into a flicker which I tried to capture on video here: https://youtu.be/HNZQIvWs5lo
I switched the image source and the artifact is visible on the slash screen as well so the cause must be with the projector. I tried cleaning the lens but this had no effect on the artifact.
Can anybody tell me the possible cause? The lamp has been in operation for 550 hours so there should be plenty of life left in it.

I've stumbled on an issue that seems to have very little(or contradictory) coverage - MAXimum screen size!
Here is my setup to be:
Projector - BenQ w1070
View distance - 2.70m(8.85 feet)
Screen - Elite Screen M100XWH(16:9) - based on BenQ screen size calculator with zoom 1.00 and 2.80m(9.18 feet) distance from projector to screen.
My question is: Will this screen be too big for the seating positions?
According THX the ideal screen is 73 inch, but I could go "little" bigger.
According Projectorcentral calculator I should get 40-45 inch screen?!?
According to the most common rule I've found: view distance = 1.5*screen width, I should get 80 inch screen.
These past few days I've been wondering on should I get the smaller Elite Screens M84UWH-E30 or even Elite Screens M80UWH(84-80 inch screens).
What are your toughs/suggestions on this?

i have a BenQ W1070 projector with about 1300 lamp hours (about 18 month old)
at first, it worked great.
after about 600 hours the colors start to get a little distorted. similer to pictures, but back then it was barely noticeable!
couple of days ago i used a compressed air can (like i use for my PC) to dust of the projector.
ever since, everything starts fine but after about an hour of working time, the color get really distorted and starts to flicker.
sometimes it even turns itself off and a red "lamp" indicator on the unit turns on.
is there any hope left?
what can be causing the problem?
thanks in advance!
