It might be caused by the logical board or a sensor of it; you have no other choice but taking it to the repair center.

On screen resolution issues


Bought a new XGA projector.../

It appears from researching that the native res for the Benq is too low 800x600 so I will never get a good picture even though most of the images I install are at least 10meg originals. Also the new projector will work in a bright room the Benq will not.

I just checked the specs on your Benq PB 6110, which has a native resolution of 800X600 and will simulate 1280X1024. When you connect it to your computer, the computer goes to 800X600, right? That is the resolution of the BenQ. How high a resolution do you want? THe highest I have seen in projectors is 1024X760, which is not that much higher. Projectors seem to lag behind monitors and Plasma/LCD/LED TVs for resolution. They must have a very small market share therefore low developement.

Here are the settings:

BD 1080p 24hz Output (HDMI): On (this TV can reproduce video at 48hz for accurate 2:2 pulldown)

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Secondary monitor


When you first switch on Does it show Benq?If not the inverter circuit has failed.If you are technically able you can try resoldering transistors on inverter board.If your display is black all of the time transistors could have failed as also related fuse etc.
And yes please check with BenQ Normally these have a 3 year warranty.
