Question about BenQ MP610 Multimedia Projector

1 Answer

Projector goes through start up twice then shuts down.

When I turn on my BenQ MP721c, it goes through the start sequence (power light flashing green) but bulb does not illuminate. It then does the shut down sequence (power light flashing orange). After that, the 3 lights come on for a second (as if power cord was just plugged in) and it goes through the 2 sequences again (bulb never comes on). Then the power light comes on orange while at the same time the Lamp light comes on Red. Then unit goes back to standby mode (as when normally powered off). The unit was manufactured in March of 2007 and I bought it in May of 2007. Only about half the estimated life hours on the bulb. Is this just a bad bulb? How can you tell if the bulb is bad? I removed the bulb and used an ohm meter to measure the two connections. Could not measure anything (open). Should I be able to measure some resistance across the two bulb connections? Appreciate any reply. Thanks.

Benq w1000 project not turning on


Look at the manual page 34, for the indicator messages. I suspect it's the same problem I have (which I haven't had formally diagnosed yet!), which I believe is a defective fan. My projector had been making a really loud noise on startup, which varied in length and volume. Recently the projector has taken to turning itself off after being on for about a minute, and the power light flashes green, with the temp and lamp lights flashing red.

My benq projector turns on for a few minutes (light and fan going strong), then it shuts down.


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.

Be sure to check the filters and make sure you have good airflow thru the proj. Cleaning filters solved our temp shutdown problem.

Green light flashing and then shuts down


Hi Gary

Have you resetted the lamp timer ? It must be done when a new lamp is inserted into the unit.

You can reset the lamp timer by holding the up arrow key on the Projector in until a online message appears. Then just follow the on-screen instructions.

If the problem persists , you will have to replace the Ballast wich is the lamp's power supply.
