I have had this projector for 3 years. Twice this last month it turned off on its own. (no bad lamp warning yet) Two days ago, the projector turned off again on its own and the red light indicating a bad lamp came on once for the first time. I turned off and on the power switch from the back of the unit. Now, when I turn the power switch on, instead of causing the power green light turn on on the console, and the bad-lamp red light turn on too (assuming the lamp is bad), nothing happens. (There is only a green flushing barely visible not on the leds but on the buttons of the console, as if a malfunction problem is happening.) How do I figure out if the lamp is bad (I removed the lamp and no black/smoky areas are visible) or there is something wrong with the unit. I see no point replacing the lamp on a broken unit, but I have read that sometimes units behave abnormally in the presence of a bad lamp, and replacing the lamp fixes the problem. Thanks!

Your lucky it lasted 1 month. The population thinks they are receiving inexpensive items from China. Instead they are cheap useless rubbish. You will find that anything from Asia costs half as much and only lasts 1 tenth of the time. DO THE MATHS PEOPLE WE ARE BEING RIPPED OFF. While Asia is getting rich.

I just solved this problem. You have to remove the lense and adujst 3 screws. It may be delicate adjustment (about 0,5 to 1mm) but I solved the problem. Was not that easy to remove the lense, access is from the fron after removing the front panel. Cheers.

Hi, I'm looking for a mainboard too. Just last week one of the PLL clock multipliers wacked-out and overclocked one of the DLP ICs. (confirmed by O-scope and service manual). Guess they timed the warranty just right before the units start to die.
I have an Optoma EzPro 737 DLP projector that accumulated dust inside the lens and for ages I couldn't figure out how to get rid of it. It cast shadows onto the picture and scattered light outside the edges of the picture. I thought I'd have to dismantle the whole lens assembly (then realised that this is virtually impossible without being an expert). I then stumbled upon a little black rubbery plastic panel on the side of the light path, which unclips. I then realised that the dust had built up on the lens that sits in front of the DMD chip (the thing that makes the picture).
Here's what I did, with the case open and having vaccuumed out all the dusty parts of the projector to avoid making the situation worse: - Took off the little rubbery panel, - Removed the lamp from the projector and placed a flashlight inside, shining into the light path (or a mirror directing light from a table lamp above) - Looking directly into the lens from close up, you should be able to see the particles of dust stuck to the inner lens (with a nice magnified view) - First tried blowing air into the gap on the side of the light path (I used a balloon pump). - Next, I poked a piece of thick nylon fishing line into the hole so that it could touch the surface of the inner lens. - While looking into the lens, I could see the tip of the nylon, then directed it to the largest dust particles and used it to scrape them off (nylon is much softer than glass, so won't scratch the lens). - This was quite time consuming but I got rid of the most obvious bits.
I'm not sure how different this would be for another model of projector - but I hope it helps!
