This is the first DLP set I've worked on, the bulb is bad and an original

only supposed to replace the entire module.
I just did a bulb-only replacement on a Mits 73827, $99 vs. $250, works
fine.
Like the others have pointed out, because of the heat the bulb operates at,
you just can't handle it by bare hands. The place I ordered mine from even
came with a glove.
As far as "doing it", on the Mits the $250 assembly pops out of the back of
the set, two screws to get the door off, 3 retainer screws to detach the
module. Once the module/housing is on the bench/table, it's two screws to
separate the housing, four screws (5 depending on the power connector) to
release the bulb and thats about it. New bulb in, reverse the above.
The bulb appears to be OEM (Osram) and is no different from the original. If
it's counterfeit, it's a pretty good one. Why they charge an extra $150 for
the housing is beyond me, it's just a plastic shell that holds the bulb, no
other electronic componets.

you're lucky, my RCA 61" cost $420 to replace that unit and for the
glove, that's to keep your greasy hands off the lamp other wise, you can
distort the lamp when heated up and pop it.
