Mitsubishi HC3000 Projector Review - Warranty
Mitsubishi provides a 2 year parts and labor warranty (US) on the HC3000 (link to specs). This is pretty typical of projectors in this price range.
Consider: The Optoma HD72 also offers a 2 year warranty, the InFocus IN76 has a one year warranty, the Sony HS-51A has two years, the BenQ PE-7700 has a three year warranty with first year replacement program, the Epson Cinema 550 has 2 years with a 2 year replacement program, and the significantly less expensive Panasonic PT-AE900u a one year warranty. The Sanyo Z4 also far less expensive, has a three year warranty, as does Optoma's slightly more expensive Darkchip3 HD7100.
So, overall, the Mitsubishi HC3000 warranty fits right smack in the middle of the pack.
