Its a problem with the inverter. check the 4 transistors, C5707 near the connectors for the backlight. If none are defective, look for the PF751 FUSE. It sure to be busted.You can replace that with another 3A fuse. Remember, you should only replace the fuse if you are certain there are no busted transistors in the inverter board. Otherwise, you now have a refurbished Benq Monitor

Check the video cable, make sure it is not loose. Try the monitor on another computer to see if it works.
If not then follow these instrucrions :-
When the LCD monitor display is dim or flickers and or has a black screen then the fault is usually a faulty inverter or the CCFL lamp. When you look at the screen at a sharp angle and you see a dim image then it is a backlight problem and it is caused by a faulty inverter or a CCFL lamp.

That cap is for the Primary power supply switching circuits. How is the DC secondary side, no blown fuse, shorted transistors in the inverter circuits? Pictures will help, email@example.com
It may have the same bd as DELL since BenQ makes monitors for DELL and HP.
