Question about BenQ FP767 17" LCD Monitor

1 Answer

Monitor randomly decides not to display

Hey, I have a Benq FP767+ 17" LCD monitor and sometimes it will not display anything on the screen when i turn it on (The blue light stays on thou with a blank screen). When it doesn't display anything, i just move the monitor into different positions and tilt it up and down and turn it on again and it'll work. This problem used to only occur when i turn it off. I clicked on all my settings and made them default and my refresh setting is at 60hz and 1280*1024. I've had this monitor for 2 years now and it's only just started to stuff up. Just today my monitor started to turn itself off (it only did it twice but it's working now) and i got frustrated that it woulnd't turn on again so i gave it a whack to the back and turned it on and voila, it works. Could there be a fault in my monitor now? should i send it in for repair? Thanks

    My benq 767 monitor after being on for thirty minutes or less it turns itself off even though I'm constantly using my computer. First the screen gets really bright and a second later it switches off. I have to hit the monitors on off button two or three times before it comes back on and stays on for another fifteen to thirty minutes and then the process starts over again.

My Benq t221w monitors power light flashes green ond will not turn on, the screen stays black, sometimes it will turn on but noe it stays off.


It is an inverter issue, you can seek a replacement but it would be more cost effective to replace the unit.

Wont power onPressing power switch, blue light comes on, the BenQ logo briefly flashes then screen stays black


Power leak causing overload on the O/L sensor.

Probably a faulty capacitor on the power board

Check to see if the video cable is connected at both ends securely.
Also, if possible, try another cable.

Monitor : no display and blue led light is blinking


The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.

Benq 17"Lcd monitor fault


Resolder the power transistors on inverter board and also check them.If display is not there at all some of this 4 transistors C5707 should be defective.Check associated fuse and Fet which drives the transistor.

Also check with Benq ,Normally offers three year warranty.

Screen displays fine for a second, then goes blank


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.
