Benq w1000+ turns on ok, but shortly after screen starts strobing brightly, then shuts down. red and green lights come on projector and sometimes(but not always) fan starts blowing frantically even when turned off. leave it for a while, and sometimes it works fine, other times it does the same thing again.

SOURCE: 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.

Had the same problem with PB2140, during startup the lamp went off and power and lamp leds turned on. This happened after the projector fell down. I read a post there hat mentioned it was probably the power supply so i disassembled the projector. I found out that a small transistor of the power supply was torn away but it was still inside the projector. I found it, put it back and the projector works just fine. Thanks!

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.

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.

it might be dusty enough to hold in the heat. it needs a good cleaning. use canned air. if you still have an issue, the fans might be running too slow or the thermister (temp sensor) may be faulty. sometimes if it gets too hot in there, the thermister needs to be replaced, too.
