Small white spots on screen acer x1230k

Your DMD chip is failing, the only fix is to replace the chip.
Also if you do replace the chip make sure you use decent thermal paste between the chip and heat sink, and clean all the dust out, especially from the fans.

Hello there.

Try the monitor with ANOTHER computer,

This will prove whether it is the Monitor at fault or not.

should have just used a duster spray.. not disasembled the unit..

The DLP chip is going bad. You are better off buying a new projector.

I have the same problem. All of a sudden there are plenty white dots all around the screen. As if 1/3 of the pixels are burnt. It cannot be the lamp because it is still as bright as before. It must be the internal screen or whatever. The "Troubleshooting" section of the user manual does not mention such thing.

Check how many hours your bulb has used as it will start to break down on the inner chrome coating.

make a cleaing, if it still is full white dots, it should be problem of DMD chips,

buy a 8060-6038B DMD chips and instal it. only cost USD184
