Usually a color wheel may take care of this problem.

Small white dots have started to appear on our screen, first, on, then a couple days later 2 more, and today we have 6 small white dots on our screen. What is happening to cause this condition?


Your problem is that the DMD device is failing. You're in luck, though. Mitubishi has recently released a replacement DMD device in order to keep repair costs down for the consumer. Take your TV to an authorized Mitsubishi servicer for repairs.

I have had a Sony KF-WS60S1 rear projection TV for some 3 years and recently had to replace the globe. I completed this as per the book, double checking all screws were tight and the globe inserted...


You will need to pull out the engine and check for any smudge on the lens. then proceed with the polarizers 3 of them they are sitting in front of the DLP chips, this is a delicates operation. the blue polarizer is the one which usually suffers burn-in (dark spots on the glass). if everything looks ok, then it means that the dlp chips are faulty, at that stage it will be uneconomical to be fixed.


Hope this helps!

This not a DLP set and does not have a bulb that the customer can replace.
It may need a firmware upgrade if avaiable.

They make two different color wheels for the Rca DLP are you positive you got the right one. As usually its a straight forward install no adjusting needed. Post the chassis number off the back of your set and I will try to help you out with it.

this indications that you have a problem with convergence. first try to go into customer menu...setup....convergence. and see if the convergence will adjust.. if it wont then you have a problem with the convergence cuircit boards.

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.
