Fit the new DMD module

A poor thermal contact between the DMD chip and the heatsink could lead to premature failure of the chip. This projector uses thermal tape between the chip and the heatsink to ensure a good thermal contact.
Re-fitting the spacer washer that fits between the heatsink and the DMD board is tricky.
Use a thin strip of electrical tape to hold the washer and bolt in place while you re-assemble. The tape can be removed before tightening the bolts.
