How is the best way to clean out all the dust, fuzz, cat hair and other stuff from the back ventilation / front speaker areas of the DLP cabinet. I know there is a lot inside and I wondered if I can blow it out by using a few blasts from an air compressor. Will this do damage by sending all the stuff to areas inside that might be bad. Like the mirror, color wheel, screen etc? It is a HLN617WX.
