Is there a start-up sequence to put the unit into 'service mode'?

Most projectors have a sequence using the buttons to initiate a 'service mode' upon power up where resets can be made. My unit is flashing the red temp light at a 1 second interval. This resulted from overheating due to a dirty filter. There are 3 thermocouples in the unit but there is no apparent damage. It seems that the microprocessor needs to be reset now that everything is cleaned and the unit is cool.
