How do I turn the power off (cool down)

Every projector I have used in the past has a soft power down so the projector can use its fan to cool the lamp down. I can not see it on this model. Is there a way of doing this or do I just use the hard power down.

    This projector has no cool-down time.
    So you need no soft power down, just turn off...simple and good.

Yeah just hit the switch and it shuts down. there is no soft power down, which tends to lessen the life of the projector. Sorry man

The projector lamps always burning out. I think, the cooling system does not work?How does the projector work?


Make sure not to shut down the projector after use. Wait until the fan stops. The fan is to cool down the bulb during and after use. Once the fan stops, then you can shut it down.

My pt-ae900u wont turn on. the lamp light is flashing red..and the motor or fan is making a soft scratching noise. I never got any warning on the screen saying the bulb was in need of replacing..but its...


Hi,
First of all check the remove the lamp and check the same. if it found burned you have to replace it. Remember one thing you have to reset the lamp hour After replacing the lamp. You can see the option in the menu.
resetting procedure.
1. inset the new lamp.
2. power on the projector.
3. Press menu and select OPTION.
4. Press enter button and the select LAMP RUN TIME.
5. Press and hold MENU button for 3 seconds.
6. Lamp reset , power off message will display.
7. power off the projector. this will reset the lamp hour.


Also Check the lamp cooling fan of your projector. may be its has some problem. its not running at the correct RPM. Do one thing, Remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now u can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. u can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the projector. power ON the projector and watch.
ok

Projector screen displaying "Searching" message. Does not recognize computer. Worked with one of your associates (Guru?) and we tried a number of solutions but none worked. She asked that I come back to...


If you are connecting to a laptop then you may need to hold the function button down and press F1, F2, F3 etc. there should be a sign with the latop on there and a sign with an external device (monitor,PROJECOR)
hope this information was useful to you.

I just replaced a power supply, it has one fan instead of 2. Works great but now I get an error message saying it can't find the fan (which I'm no longer using), how do I get rid of the message?


replace the fan. it needs all the fans the projector was designed with to properly cool it down. without all the fans, the lamp will overheat and cause premature lamp and projector failure. the fan has 3 wires- ground, power and sensor. if the fan spins too slow or not at all, the projector will shut down to prevent damage.

so, replace the fan.

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.

Infocus in26 fan runs continually


Hello,
The fan does run continuously on this projector however it should be running very very slow when the projector has completed it's lamp cool down routine.
The reason for this is that a portion of the switching power supply remains energized (running) when the projector is at rest. But as I mentioned it should run very slow in this state. If it remains running full blast then most likely the fan speed control chip is shorted which can cause fail 2 ways, either the fan 1. runs full
speed or 2. remains stalled (then the projector will go over-temp and shut itself down) I hope this answers you question.

Cheers

Projector shuts off after about 45 minutes


Just a long shot, but...

I have an epson 9000i that did the same thing. Turns out that unit has a small fan (I think 60mm) right next to the power supply to keep it cool, in addition to the large fan that exhausts past the lamp. The fan runs non-stop as long as the unit is powered-up for two reasons I can think of - keep the power supply a little cooler, and the lamp a little warmer so there's not such a temp difference when it powers-up. Long story short, that fan had died. I replaced it with an aftermarket 60mm fan and it's been working fine ever since. Hope this helps.

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."

Mt800 projector


First I would suggest cleaning the filter on the bottom of the unit where the fan inlet is. Over heating can cause many issues with the video controller in the projector, also shortens the life span of the bulb, always let the unit cool down when turning it off (let the fan run when you turn the power of by top button, never unplug and use the power switch on back. until the fan shuts off.)
