Question about Optoma RD50 Television

How to fix black shadows appearing on both sides of the screen?

I have an Optoma RD-50, rear projection DLP set. I recently started seeing black shadows creeping onto the image from both sides of the screen. The shadow on the left side is narrower than the one on the right... also, the left-side shadow is angled at about 5 degrees whereas the one on the right is straight up-and-down. Is this a "mechanical" problem like a mirror or projector being out of alignment, or is it a more serious "electrical" problem with one of the components? If the former (hopefully), is there some adjustment I can do myself to avoid the $400 charge for a service call I was quoted by the Optoma tech I spoke to? Thanks for any advice you can provide.

This is a common experience to many Optoma owner's who thought they were buying quality eauipment - RD50/a and RD65/h. It has to do with mirrors within the light tunnel coming loose. They used inferior glue at production. I tried to repair them myself and failed and ended up installing an entire light tunnel ($$$) myself, but most should just buy another TV and sue Optoma for putting out an inferior product.

Optoma RD-50 DLP has dark vertical shadow on right side of screen

turning off the main can be very harmful to rear projectors if you dont wait for the cooling off period, for instance when you turn off the tv from the remote, the fans inside are still on in order to dissipate the heat given out by the lamp. as a result some of the lens inside the engine may have burns-in caused by excess of heat.thus leading to shadows on the screen.

hope this helps

This can be the sync wheel assy, failure in the drive circuit for the display chip, or an illumination fault. You will have to give the set out for service.

Small bluish, black triangle at far right corner

This is the same problem as other posts have mentioned about the right side of the screen having a bluish-balck stripe down the side of the screen. Here's what's happening. There's a small light tunnel which has 4 very small mirrors located just behind the color wheel. The lamp shines light through the color wheel as it turns and the light goes through this small tunnel and is then relected off several mirrors before it is projected through the lens and onto the screen. Optoma apparently did not use a very good heat resistant expoxy glue when they assembled these mirrors and over time the mirrors drop down causing a shadow effect on the screen. It can be repaired without paying some repair shop a small fortune. Previous posts have a solution from another contributer whihc includes photos. I had to repair mine and it's worked fine since I used a decent expoxy to hold the mirrors.
