I had the same problem and found that Q808, Q809 and Q805 had failed and which if left long enough can also cause PF801 to fail. I also replaced all of the electrolytic capacitors during the rebuild as it was only a few dollars to do so.
Although in my case Q815, Q816 and Q812 were fine I suspect that they may also fail in time.
Here are the parts which should be available at most electronic stores or online.
Q808 & Q809 - 2SC5707
Q805 - IRFU9024N
PF801 - 3 AMP PICO FUSE

this kind of trouble is very common to all LCD monitors. your inverter is shutting down. please check all capacitors at the power supply some are badged or blown on top due to hot pressure inside.

I have the same problem and have gotten it fixed twice. Going to be my third time now. Every time, they replace a costly part. I've submitted multiple emails during it's warranty through the tech support form at BenQ's official website and never once gotten a reply.
To solve this problem, pay to have it repaired and auction it in a yard sale to cover the cost. Then never buy a BenQ again.
