SOURCE: 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..

SOURCE: "clean filter" prompt

Hi there

Not at all. This promp automatically appears after a certain amount of hours.

To get this message away , all you have to do is go into the Menu and reset the Filter Timer.

SOURCE: 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.

SOURCE: benq 8250 projector shuts down

Hi david115

I've had this problem MANY a time before and what BenQ does wrong is that they only replace the two main fans at the back of the PB8250 , they should in fact replace both the fans and the Mainboard. This is unfortunately the only way to get around this problem.

SOURCE: my benq projector turns on for a few minutes

if it goes through shut down mode (lamp first and fans run a while), reset the settings to factory default. while you're in the menu, check the lamp hours (under settings). if they're close to 2000 hours, replace the lamp. if the projector shuts down immediately, fans and all, you have a power supply problem. you'll need to replace it.

  • Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

  • 2
    Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  • 3
    Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

  • 4
    Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  • 5
    Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

I have a Benq w710st DLP projector and when i turn the power on after a minute it turns off. The power button turns off and both the lamp and temp lights turn red. How do I fix this and can I do it my


New bulb is probalbly needed. You need to find out what zero means on that projector. The real problem is finding out why the cooling fan is not turning on. This is probably the reason that the temp light is coming on.

My projector screen has js turned all bluish! Instead of the black background, it is all blue, and the entire movie color is messed up...the lamp life is only 300hrs!! i've had the projector for almost a...


the light filter on the blue lcd is fried due to excessive dust and heat. clean it out with canned air and replace the filter. unfortunately, you might have to replace the entire optical engine because benq doesn't sell individual parts for it.

Color problem


Check the cables connected to the back of the projector. reinsert the cables a few times to get a good contact. Jiggle the connection at the projector to see if there is a bad connection, do this while viewing the image on the screen. If everything is good and no response to the connections, It might be the main/input board is bad and will need replacement.
