I commend your courage in taking your monitor apart. I hope it was out of warranty when you did it; because it is out of warranty now.

I have no idea where to find the info you are looking for. Monitors are cheap now, though.

Monitor blue light comes on, the picture is on for a brief second but screen goes black, how do I fix this problem please.


I have had this problem before and had to contact the manufacturer. I was able to send them back and the manufacturer sent me a replacement. If your monitor is under warranty it should not cost you anything.

No display


BenQ made a lot of monitors for Dell. You may want to look at Dell pictures.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Power indicator is on, but there are not any signals on display, not responding on any of buttons on front panel either


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Open it up and look for burned or some cold soldre joints. After resolder it should work.

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.

Monitor not showing anything


If it is still under warranty from Benq (3yrs), call them for a return. I have one (FP731) and did the same thing. There is an IC within the monitor that is bad. Pretty soon there will be nothing on the screen.
