    Power failure...found the blown cap and now bulb turns on but no pic. This is a common problem & BenQ won't answer service call...will never buy another.

    The problem is altitude. We are at 7,000 feet and operating this unit on normal settings triggers this over heating problem. We changed the settings to economic mode and have had no more problems to date. This also saves up to 20% on power and extends bulb life.

    Hope this helps someone in the future.

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.

Lamp will not stay on more that a minute or so. Why? All of the fans are working and none of the vents are clogged but it is like a thermal switch shuts the lamp off.


if the projector is overheating, it will shut down. blow out the projector with canned air. the dust keeps in the heat that the fans are trying to expell. if it has shut down from heat to often, you'll need to replace the thermosensor. if you are not sure it's temp related, check the lamp for bulges and black spots. replace lamp if necessary.

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.

My Benq PB6100 shut off after a few seconds


I had the same problem.
First thing to do is look up the owners manual, unless you happen to still have it, then verify the the sensor for the second (or rear something that sounds not like first) temp sensor is going off. If it is basically the fan that sends air into the lamps compartment may be clogged. I have had mine for several years and recently had the same problem. I almost went out to buy something new until I convinced myself that there was no harm in taking it apart and trying something. Good thing too, since all I had to do was clean the fan and reassemble. After that it stopped turning off by itself and I haven't seen any red lights.
Good luck to You!
