Church 3m s40 doesnt work. It powers up, the fan runs, then a red light comes on the "lamp" and "power" leds. I bought a new bulb for it and it has not improved the problem. HELP!


It's likely the lamp ballast has failed. The ballast powers on the lamp. You can also reseat the lamp & make sure the lamp cover is replaced evenly or the safety shutoff switch under the lamp door may not be depressing which will cause a no start.

Power will not come on.tried many power chords none work light will not come on


are there any leds on? if not, replace the power supply. if there are, such as one blinking red, could be the colorwheel, ballast, or the lamp has expired.

The lamp indicator turns on


The clicking noise is the protection switch that keep shutting down the unit. This happens when an internal fault had been detected.

Do the following:

Unplug the unit from power for some time.
Remove the bulp and refit it in place.
Restart the unit.

If still in protect mode (clicking , lamp light and no start), then there is a fault.
When the problem is the lamp, the lamp light will come on, but usually protection does not click.
Before buying a new lamp that is expensive, have the projector checked, testing with particular attention the high voltage board that will supply power to the lamp. That may be the fault.
If you have a replacement lamp in storage replace the lamp first.

Unit powers on momentarily, bulb comes on for about 4 to 5 second


if a fan is blocked from turning then the power up self testing will detect a problem and stop it from further operation. thats why you have to unpug it

The lamp cover has a disconnect that wont allow the unit to power on while the cover is off.

Try taking the lamp cover off and bending the little piece of metal you find underneith.

It worked for me.
