I'm not sure how well it works in HT5550/W5700 but couple of my local dealers mentioned me when I was visiting them that they do not recommend BenQ and claimed they have had a lot of customers having issues with dust. I realize this is not as high end model as my W5K but are they in reality that bad these days?
The light engine IS sealed. But dust can get into the chassis and if it settles on the inside of the lens it could cause blotches. But, comparatively speaking, there is far less chance of this happening (and it’s far easier to fix) than dust getting into the relatively complex light engine of an 3LCD/LCOS.
DLPs are incredibly simple on the inside. Even a 1080p 3LCD or LCOS has a complex array of panels, mirrors and prisms. A DLP pretty much has the color wheel and the ONE DLP chip— which is sealed.
What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...
