If it is not something simple, you will most likely have to send it to
the Sanyo service centre to have it properly repaired. Most of their
servicing is done at the board exchange level, and then they do the
calibration of the boards that they change, if necessary.

Is there an hours counter that you must reset on that particular model,
after changing lamps?
