Question about BenQ FP92G+S (Black,Sylver) (Silver, Black) 19" Monitor
More likely to have power supply problem, that will be the first place to check, look to see if it has any caps with leaking/bulging tops/seal, burnt spots, shorted transistors in the backlight inverter board, cold solder joints. Look at my DELL albums (BenQ made a lot of monitors for DELL). Be real careful when removing the front bezel, you can easily rip apart the cable.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
