BenQ FP731 LCD monitor turned black while working.
1) With external light I can see the screen.
2) My best guess: backlight seem to be not working.
I'm new with monitor repair. My questions are:
1)What precaution I should take while opening the monitor. Some steps were welcome.
2)Is it some fuse issue? If so, where to look for?
3)If it is inverter issue, what and where to look for?
4)If it is backlight issue, how to change it?
Thanks
