When I switch on my FP767 monitor the light appears as blue, but nothing on the screen.

open back cover of your monitor then adjust the screen control of the flyback to your desired brightness

Blue cast on the screen? Then check all the pins on both ends of the video cable, try it on another PC to make sure it is not video card problems.

Check the cable on your monitor through video card if there is loose connection. Check also the video card by replacing it with your extra video card if you have. I think the problem is not the monitor but the video card.

Have you attempted to enter the on-screen menu system for the monitor? There should be a reset system reset option somewhere in the menu selections. If not give that a try.
Also you might want to check your monitor cable. Unplug then replug it in. If you still have a blank screen you might want to try the cable on another monitor if that's possible.

If the cable is not the problem then that leaves the monitor itself or the video card if your system is equipped with one. Check the back connectors and locate the video output plug. If it is located close to the keyboard, mouse, Ethernet and usb plugs it is what's known as on-board video. If it is located below those other plugs it is a video card. Shut your system off and disconnect the power cable. Open up your case and make sure that the video card is seated correctly. They can come loose.

Your only other option is to try your monitor on another system.
I really hope something here helps. Good luck

change the board

Try checking the cables and disconnect all cables from system and monitor and reconnect all of them.

And in case it does not work,Please change the cable coming from tower to the Monitor as it seems that it has gone bad.


Hope this Help.
Cheers!!!!

Check four 5707, two 9204, and one bel 3A slow blow fuse. Also re-solder all cap and transformer.It's quiet common on benq and Dell(benq OEM) 17 LCD. For detail google "benq 5707", sure you can found. Good luck

You have to plug the audio wire from the monitor into your speaker jack on your computer.

The problem is with front panel switches.The contacts maybe leaky.You need to replace all the six switches.

Different faults here.
First fault is no power, it is bad capacitors on the power board.

Second & third faults are the inverters. (power but no image visible, but feint if you shine a light into the screen)
Check the 4 transistors on the main power board for shorts.

If you are unsure what that means, then take it to your local TV technician, he should be able to solve it fairly cheaply.

Hope that helps.
