Have a Benq FP767 monitor. Got it back in 2003 or 4. Worked fine for years; even with new PC and video card. I would ordinarily leave my system unit on and turn off the monitor. Very recently, past couple of weeks, the monitor is not coming on immediately. When I would press the button, the indicator would gently flash off and on. It would take a few tries before getting the monitor to finally come on. I did see a brief flash or something on the screen that would imply "Monitor is old - need replacing". Is this a correct assessment? How long before I need to buy a new one?

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

First check the vga cable, video cards of your pc.if all of these are ok open your LCD monitor check the power board for boated capacitor, open secondary pico fuse or fuseble resistor, replace it with the same value. The defective lcd panel can cause of dim dispaly but the power is ok.

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

This means that a video signal has been detected but it is beyond the range for display. As an example, if the monitor can only display 1024x768 and you send it a signal at 1280x1024, you will get that message. Try to downsize the display settings on your computer system until the monotor works.

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.

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.
