Recently, most of our customers who using DLP projector NP210, NP215, NP216, NP115, NP110 have white dots on screen. Before understanding the reason that cause the error, they tried to replace a new projector lamp. Even they tried compatible replacement projector lamp or Original OEM projector lamps, the main error can not be fix.

Actually, the white dots mostly caused by a aging projector DMD chip (Digital Mirror Device). They were trying to find the problem by searching in the internet or check for their projector manual. Unfortunately, NEC will not tell you the secret. Because if you ask them to help you repair the projector, they will charge you hundreds of dollars.  If your projector is still under warranty, you are lucky to ask the supplier to offer you a free DMD Chip which can save you hundred dollars.

However, if you find out the projector white dots is caused by aging projector DMD chip,  you still do not know which dmd chip fix your projector. After searching from the google or checking from your projector manual, you still did not know the correct dmd part unless you take off your projector cover and check for your used DMD chip. But we found lost of our customer do not hope to do this before having a new replacement chip.

After taking out the projector cover, you may find a cooling plate around the projector lens. The projector DMD chip is always protect by the cooling plate. The only thing you need to do is follow the cooling plate, and take it down carefully. I suggest you open your phone cam when you take the chip out in case forgetting how to install it back or missing one of the parts.
