What is the cause of blances points on my beamer Benq MX 711?

plug the projector end of the cable into a monitor and check that the video is OK.
then reconnect to beamer
make sure the rgb socket on beamer is configured for pc and not component video input

turn on the beamer and hold the exit button for 3 sec. it will ask you if you want to reset the bulb timer

Hi there,

1) Turn off the BenQ power, before connecting your VGA cable to the Toshiba laptop.

2) Once your laptop recognises the BenQ unit, you then need to tell your laptop to send an output signal to the BenQ - you do this by pressing your 'screen output' button (this is usually one of the function keys and you may need to hold the key for 1sec). The output function key can choose either single VGA output, or both laptop screen + VGA output.

you have a problem with either the fans, the ballast, or the colorwheel. if the fans turn on, listen for a high-pitched whir. if you don't hear it, replace the colorwheel. if you do, replace the ballast. if the fans don't spin, replace them.

I just replaced my lamp for the same beamer. Took me a while to figure out how, but if you know how, it is easy. Turn the beamer on its back. In the middle, you will see a black rubber (small), it covers a hole and a screw is in the whole. Pull the small bblack rubber out. Unscrew the screw. A small cover will come loose. And there is the lamp, You have to pull out the power cable, and than only one little screw that mounts the lamp to the inside of the beamer.

It's easy!
Hope you will succeed,
