After 5 years of service begin my BenQ beamer (MW811ST) me in the lurch. In the projected image, there are now white dots (pixels) to see and more coming every day more and more.

Left and right to hear I'm not the only cockpitbouwer with the same problem...

This defect is due to a defective DMD chip. This chip is made up of millions of micro-mirrors and that start now one for one to fall out. With the result each time a white pixel there.

To the projector for repair is not an option since it costs +- €600 amounts. For that money with a couple of hundred euro extra, you can now have a new HD projector to buy ...
Self repair is also, and this is only half of the price but that is probably again stay of execution.

For now I still continue with this projector, since the number of white pixels is still limited, although there is in the future anyway, a new (HD) projector will be overselling, but then one DMD chip!!!!!!
