Why are there white spots in my optoma pt100 projector?

generally, the projector noise possibly comes from the color wheel or fans. but PT100 is LED projector, so the noise should be from the fans.

it is DMD chip issue, can't be fixed, only replace it.

this chip is a bit expensive,you must hold in readiness for cost much.

this could be dust, or dried water spots from moisture

firstly make a clean for your projector DMD chips or color weel, if it still ahs whie spots, It should be dead pixels, since for the DMD chips issue. you have to replace a new DMD chips. i have DMD chips fit for Optoma EP761, it will cost USD123 with shipping

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.

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.

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,

Hello, I have the same problem with a pico 201, and can not solve it, I can not contact optoma support team

If you focus the image on a screen up close to the projector and notice small rectangular black and white spots, then you have pixel failures.

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.
