We have a hitachi XGA CP- X275 projector, the lamp & temp lights are flashing red but the lamp is still illuminated, what's the problem ? Thanks

There could be several causes for this. Does the cooling fan come on, it may be defective. There could be something blocking the heat sensor. Is it possible the connector didn't get fully attached when you installed the new lamp?

Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

• A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
• A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.

Goodluck..

Call hitachi service center to fix it. It may have a circuit problem or the lamp itself is deffective.

Read page 69 of your user manual. The color/flashing patterns of the lights indicate what is wrong with the projector:

check the bulb is fully seated and connected. otherwise it could be the bulb firing board or connections to the bulb.

Normally when a unit like this shuts down, there are indicators that will show why. Are any of the lights on or blinking when this happens? The most common cause is overheating. Is the lamp indicator RED or the temp indicator? A little more detail would be helpful here. Can you also indicate how long the unit runs before shutting down?

Thanks,
Dan

with the projector connected, go to displays in system prefrences and click on the detect displays button.

Yes, this unit is made for either or solution. If you look at the under side, you will see three screw holes, these are for your mount kit which you can get form http://www.mountsandmore.com/Projector-Ceiling-Mounts-C13810.html?refid=G6435.%22projector+ceiling+mount%22&gclid=CIyfl7G_2pgCFQEoGgodXmajdw

There are other sites as well.

Hope this is not too late.

This is what your projector's user manual says about a flashing "TEMP" light :

"The cooling fan is not operating. Turn the power OFF and wait approximately 20 minutes. After the main unit has cooled down, please make confirmation that no foreign matter has become caught in the fan, etc. After performing any needed maintenance, turn the power ON again; if the same display is displayed, then please contact a sales store or a service company."

Hi Jenrowe

Try resetting the lamp and filter timer , if this still occurs reset the whole mashine.
