Its a bad DMD chip. Seems this is a common problem with the PK-301's sadly. Mine is out of warranty and a new chip runs about $180.

Why are there white spots in my optoma pt100 projector?

you have pixel failure and the DMD chip will probably need to be replaced. Ask the Optoma service agent to give you a quote beforehand as to how much they would charge for this service.

I have a Optoma HD 67 projector and suddenly it has a lot of white spots on the screen, even if you remove the input cable the white spots stay there

as greg instruction, it is very detail,

usually, white dots problem is reason of the DMD. perhaps the manufcaturer can't directly and singly sell a parts for end user, they always let you send broken machine to their repair store, then ask for high repair cost.

actually, optoma HD67 projector with 1280*720 pixels, so i think you should buy a 1272-6038B DMD chips, if you need further help, please freely contact me again,

My optoma is projecting white spots onto the screen. They seem to just appear. Some have began by 'sparkling' for a while and then they stay white perminantly.

if it is a DLP projector then the DMD on the engine is likely bad or the main board is bad. The white things are pixels.

Global projectors is one source. You need to find out from Optoma the chip you need or take apart the machine and look at it. From China they run about 200 bucks. I've only done Mitsubishi so far.

What does the DMD chip look likes? Where I can find it? Why is not possible to have the chip only with the serial number of my projector?
gmontgome595 Dec 20, 2012

Optoma should be able to tell you if you call their tech support line. They may not want to. Here is a video showing how to find the DMD in a Optoma its not my video though.http://youtu.be/uJpGvrz3yR4..
