Re: Benq FP737s - Not working suddenly - Black screen
Disconect the screen from the computer, after you have to see the no signal sign on the screen.
If you see the sign check the setup setting and the video card.
If not, use a flashlite to check if you see the picture on the screen. If you see the picture or the no signal sign when disconected, backlight or inverter problem.
Check what is cheaper repear or buy anotherone.
If you buy a new you can sell this on ebay for part. Buy a new with extended waranty. (tip: samsungs have a function to change the setting with a push of a button from movi setting to text reading you can trippel your screen life that way!)

Try connecting the monitor to a different computer, e.g., a laptop.
The power-cord to the monitor seems to be OK.
Check the "data" cable between the monitor and the computer -- try a different cable.
With the monitor turned on, restart your computer, and watch the monitor. The computer should show some start-up messages (white text over black background), followed by the Windows "splash" screen. If it does, the monitor is working correctly.
On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!
dreaded capacitor issue. benq's were famous for it. if you are handy with disassembly and careful you can take it apart and do it yourself. look for any capacitors with rounded tops. i fixed one ... the part is only two dollars or so but it's a good feeling to know you fixed it instead of tossing it.
Disconnect the signal cable from CPU and power on.You should get a BenQ Blue screen.
If no Display,Problem is definitely monitor related ie monitor has a hardware defect most probably the power/invertor board has a few blown components.
If you are technically able,you can dismantle monitor and check components on the Invertor board which you may find on my other posts.

Dor, BenQ has a 3yr warranty on their monitors. I would contact their tech support and receive an RMA to return it for repair. It will cost you shipping out there but they will ship it back. I has a BenQ FP731 myself and it blew a capacitor inside that allowed the screen to stay on. Fixed it and had it back in 5-7 days. Good luck.
