Is it the DMD chip or the DMD board?

It seems my DMD chip on my Acer h5360 DLP projector is failing(dead pixels shoving as white spots all over) and I'm considering ordering a new DMD chip from some Chinese shop.

I've already got a DMD board lying around because I first thought that was the problem - after taking the projector apart though I could clearly see the faulty mirrors on the DMD chip so I just put it back together with the same board.

But now I'm thinking - could it be the mirrors are simply stuck because of the bad board and moving the chip to the new board could fix it after all?

Answer this question I have this problem too

Is this a good question?
