I'm in a similar boat. I had the power supply from my IN76 repaired last September, and recently the main circuit board started failing (HDMI HDCP stopped working, but otherwise the projector works OK). Just talked to Projector Doctor, and Infocus has stopped supplying parts for this model. Hopefully they can repair my existing board. Otherwise I'll be selling the projector and extra bulbs. How much would you want for your old projector (and does Projector Doctor still have it- that would make things convenient).
