You may have a fan out or somthing is blocking the vents. Have you looked to see if it has a filter? some DLP units dont have filters but most LCD units do. If the filters are some what clogged then it may not be cooling good and tripping the thermal shutdown.

Projectors use high power bulbs that get SUPER hot and they use a thermal sensor above the lamp so if it isnt cooling properly it wont start a fire. It may have other issues but i would start here because this is normal maitence on projectors.

Most projectors require that you leave plenty of space around the projector ,so it can keep itself cool.Also they have a filter that needs to be cleaned monthly. Follow this link and click on the "User's Manual" for directions for cleaning. Good luck,I hope this solves your problem :) http://www.projectorcentral.com/BenQ-W7000.htm

Benq MP 721 projector purple colour when it projects.


You are missing one of your primary colors and this is usually to a faulty pin where you are connecting your vga cable to. It could be either the pin on vga port of your projector or it could be the vga cable itself. Please look at the pins especially if you are using one cable to try with all the compputer.

Only bottom half is shown on screen from our Benq


Try lowering the resolution of your pc to a lower amount that the Projector can handle. Start as low as 800x600 and try working up from there.
To change pc's resolution: Right click on the desktop, click properties then settings and try sliding the resolution adjuster and testing each one with your projector. wait for the projector to resync itself each time.
good luck!
