    well i took it down (it is installed on the ceiling) and checked the light bulb. I then checked it while it was down and it worked su back up it went and it quit working again took it back down and still not working. So I took the bulb out again and checked it put it back and now it works again. mI have not put it back up to see if it will keep working yet.

    Ok yes there is more than enough air space. I checked the vents and the filters. The fan would start but the projector would only begin to start then turn off after maybe 2 or 3 sec. Since I took it down yesterday I have run it twice without a problem. It seems to be only when it is mounted upside down that there is a problem.

    Could it be a ballast? Yesterday before I took the bulb out again it would not run upside down on the table but it did not run right side up either. It was after I took out the bulb and replaced it that it worked but I still have not tried it upside down yet I will do that tomorrow and let you know what happens.

Do you hear the fan start up? or does the projector lamp come on (you start to see an image)?

If yes to either:

When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down
to protect the inside of the projector. The POWER indicator
is blinking while the projector is being cooled down. When
the projector has cooled down sufficiently (to its normal
operating temperature), it can be turned on again by
pressing the POWER ON-OFF button.

Note:
After the temperature inside the projector returns to normal, the
WARNING indicator still continues to blink. When the projector is
turned on again, the WARNING indicator stops blinking.

Then check the matters below:
– Did you provide appropriate space for the projector to be
ventilated? Check the installing condition to see if
ventilation slots are not blocked.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of airconditioning
equipment.
– Are the air filters clean? Clean the air filters periodically. Let me know if you need to know how to do this.

If no to either:

When the projector detects an abnormal condition, it is
automatically shut down to protect the inside and the
WARNING indicator will be red. In this case, disconnect the
AC power cord and reconnect it, and then turn the projector
on once again for check. If the projector cannot be turned
on and the WARNING indicator emits a red light, disconnect
the AC power cord and contact the service station for check
and repair.

Please let me know if this helped solve the problem. If not, is there anything else you observed - whether or not you believe it's relevant.

    Interesting, but still not enough info to pin down. You didn't say whether you checked these, which could be helpful:
    – Did you provide appropriate space for the projector to be
    ventilated? Check the installing condition to see if
    ventilation slots are not blocked.
    – Is the projector not installed near the ventilation duct of
    air-conditioning equipment which may be hot? Install the
    projector away from the ventilation duct of airconditioning
    equipment.
    – Are the air filters clean? Clean the air filters periodically. Let me know if you need to know how to do this.

    Also:
    -Did you hear the fan start up? Can you tell whether it sounds the same as before the problem?
    -You might try running it upside down on the tabletop rather than installing it on the ceiling and see if that chaanges anything.

    Let me know.

SOURCE: My data projector eiki LC-Xb23

If the power light & warning light both flash red, this indicates that the projector is overheating. Once the projector has cooled down the warning light would continue to flash red and the power light would be solid red.

You should clean the air filters.

The filters are located on the underside. Disconnect all cables and invert. remove the 2 air filters located at the front and rear by pullingthe latches. They are both rectangular in shape.

Being very careful not to damage them, you should rinse the dust out and leave them to dry fully before replacing them in the projector.

This should cure the problem.

Probably a fan that doesn't rotate, or one of the many sub-voltages is absent on the mainboard due to short circuited capacitors ( SMD's)

My projector doesn't stay on. what's wrong?


either the lamp cannot strike (meaning a ballast or lamp issue) or there the fans are not up to speed to sufficientl;y cool down the lamp and therefore shut down to avoid damage.

Won't power up


Hi, The owners manual says that if the red light is flashing, it is an indicator that it is ready to be turned on (use remote or onboard on button); flashing red & green - too high temperature inside, the unit is overheated. Check and clean the air filters; If the red light is steady, abnormal condition and you have to call for service. A copy of your manual is available at http://www.eiki.com/resources/resourcedownload.ashx?filename=/ownersmanuals/om_xb25_20_sb20.pdf Hope this be of some help. Pls post again how things turn up. good luck and kind regards.
