Abnormal Behaviour I have a Mitsubishi SL1U. The power and Lamp LED are always red when I power up the projector. Tey stay red all the time and nothing else happens. I have replaced the lamp, still the problem persist. I have looked at the maual and it states that I have to contact the dealer. Unfortunaetly the dealer is no longer around. Could you please advise. Many thanks

hold down power computer and video as you plug in.

READY light is green when the projector is ready to be switched on
LAMP is dim when the projector is ON, but goes bright when it reverts to STANDBY.

Check that the lamp cover is fully down and the cover switch is activated

check the lamp cover and filter covers are secured properly

This means that an abnormal condition is present in the machine.
Contact mitsubishi.

if it were just the red and green blinking on the power, then that is the lamp cover not on fully.

anyway check the lamp cover is fuuly in, and check the filter cover and filter

Press the < and > and power buttons on the projector all at the same time.

Hello toma_leonard,

First check your lamp to make sure it is seated properly in the socket.
Then check all of your interlocks (see your manual for locations), these are usually located on any hatches or doors that allow access to the lamp and or fan area. Once you check your interlocks make sure the filter and fan area is clear of dust, (some projectors have air flow sensors), and the recheck the interlocks. Once this is done , If the interlocks are not broken, or the lamp fuse blown, the projector should be working. If not it is the lamp that needs changing.

I know this may be expensive, however these lamps do go bad, as much as we wish they would not.

If you still feel it is not the lamp, have a technician check the voltage levels to the lamp and the levels of the control board circuitry.

I hope this helps,

Thank you,
