I DID REPAIR A MONITOR WITH THE SAME PROBLEM. IT TURNED OUT, THAT ONE OF THE TWO HIGH TENSION GENERATORS FOR THE 2 LIGHTTUBES WAS BURNED OUT. BY REPLACING THE POWER TRANSISTORS AND THE 3 AMP. FUSE ON THE MAINBOARD THE MONITOR IS RUNNING AGAIN VERY WELL.

It isn't the backlight. I took mine apart and found the power supply board to have 4 fried IC chips (discolored, brown). A bad backlight usually shows symptoms before it goes out ( half the screen is displayed, screen dims over time...) BenQ is just made with sh*tty parts and I found out the hard way because those theives to my cash for this garbage monitor. I'm sticking with the reputable brands from now on... Please be advised taking apart your monitor will void the 3 year warranty. BUYER BEWARE with shady brands like benQ....

I have the same problem. I've had this monitor for about 2 years. The monitor was working fine, then black.
I'm not a computer tech, but I will try to fix it. Just wondering Tom, how to fix the blackligfht, and where to purchase this light?
Thanks in advance.
