sorry for the delay.

After replacing the lamp, you will need to reset the lamp hours to stop the red flashing light.

To reset the counter:
Resetting the LAMP RUNTIME
If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure should thus be completed within 10 minutes.
1. Connect the power cord to the projector and a wall outlet, and switch the MAIN POWER on.
2. Switch the POWER button.
3. Press the MENU button to display the menu.
4. Select OPTION and press ENTER.
6. Press and hold the ENTER button for approximately 3 seconds.
7. The confirmation screen will be displayed and select OK.
8. Switch off the POWER button to reset the duration of the LAMP RUNTIME.
9. Confirm the duration of time in LAMP RUNTIME is reset to "0".

The projector shuts down prior to being able to get the menu up to reset the lamp hours

Ok, then it seems to be going into Protect mode - the power supply to the lamp may not be good; this can happen if there is a fault on the lamp ballast board.

Approximately how old is the projector?
