These small fans are prone to failure; try to access the blades to see if they are being impeded by accumulated dust and also push gently on the blades, left then right, to see if there is any wobble of the shaft.
The fan probably has a sleeve bearing and these are prone to wear and also to stick.

Red power, blinking red temp


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..

I have a Hitachi CP-X417 projector that keeps blowing lamps. Smells like something is getting extremely hot.


It sounds like you may have a broken or inefficient / blocked cooling fan. Check the air filters and make sure it is very clean and dust free. Also listen to hear if the fan is running at what you think is a normal speed - not irregular or start / stop. If this is all ok then it may be an issue on the d.c power supply to the fan - don't spend more money on a bulb until you check this out.

Optoma hd65 projector new bulb wont turn on...cant reset timer!


I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.

LCD projector still not working after lamp change


Sounds like you have a faulty ballast. I recomend changing it. This is your lamps own power supply.

Hitachi projector temp light


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."

Your user manual is available at the following link :
