Perform a Factory Reset:
1) Plug unit into AC power, so that all the lights come on as mentioned.
2) Press and hold "MENU", "ENTER" and "INPUT" (all together) for at least 5 seconds. Error lights will clear.
3) Turn OFF by POWER button, wait a few seconds.
4) Turn power ON by pressing the POWER button.
The projector will turn ON, but will take a while (1-2 minutes) to load firmware.
5) Recommend to go into Menu and at the very bottom use the "restore all defaults"

I have just serviced a Casio projector similar to this unit. I cleaned the ribbon cable connectors with a burnishing brush. I also found two screws that were jammed between a circuit board and the optical block. After cleaning the connectors and removing those two screws the projector started working fine.

This is fairly uncommon for a repair, but it may be worth a try.

FIRST LOCALIZE THE UP/ DOWN/ LEFT/ RIGHT AND MIDLE BUTON- ON FUNCTION CONTROL
OK...
KEEP PRESSD FOR 10 SEC
INPUT / MIDLE BUTTON FROM FUNCTIONS/ AND RIGHT ARROW

RELEASE THOSE BUTTONS
NOW YOU SHULD GET THE ERROR RESETED.

NOW YOU HAVE TO INITIALIZE THE UNIT:
POWER OFF UNIT( FROM POWER BUTTON)
POWER ON
PRESS AGAIN: INPUT/ MIDLE BUTON/ RIGHT AROW TILL SHOWS A SERVICE MENU ON SCREEN
CHOSE INITIALIZING AND RESEAT UNIT.
GOOD LUCK...GO CANUCKS
