you must change the lens. the cost is high. see the sony site for replace the parts.

to clean the lamp: no chemicals, nothing abrasive. you can touch the outer glass (not with your fingers), but do not touch anythjing inside the bell. best thing to use is a microfiber cloth. your lamp is nearing or has passed 2000 hours of use. the projector is telling you to replace it before it blows (and sometimes shatters). after you replace it, reset the lamp timer (through the menu).

Having same problem without lamp change. Did you ever find a solution?

Your response would be GREATLY appreciated. :)

Give input signal to the projector and see that if the menu appears or not on the screen.
if menu comes on the screen then put the backgroung color to blue, instaed of black.

if nothing comes on the screen, then the LCD panels are faulty.

You need to clean the filter , the unit is shutting down so it doesnt over heat..look for online manual on how to remove filter and blow off dust.. Good Luck

HI there

This might only be a dusty lens on the inside. But it could also be a faulty Mainboard or LCD's.

Take it to a Service Centre and ask them to check it out for you. They normally quote first and then repair if you give them a go-ahead , you've got nothing to lose.

There may be a dust fleck on one of the LCD screens inside your projector. I had a similar problem and managed to clean it. But it requires you to dissassemble the entire projector !!!. If you are not technical, don't do this yourself. !!!

Problem resolved by swapping the video cable, simple really!

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!
