| Have you ever changed the lamp? OR,
Because you light engine is defective. Call Hitachi customer support and bitch up a storm and see if you can at least get them to ship you a light engine/optical block for free. The sets are nice when working but research the 50V500A. Same thing. Bitch even louder and they may pay the labor also.  |
