    I have a Benq FP737s Monitor that is blank also. I have opened it up and checked the fuse - all ok. I have managed to get green and orange lights out of it - but nothing else. Can you help please ?

    Seems a generic 17" Benq problem - I have an FP737S doing exactly the same. Green light/yellow light on power button, otherwise nothing.
    Anybody got it fixed by resoldering those transistors as suggested?

    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.

My monitor is not responding. I have a blank screen and my power led is flashing green, none of the front monitor buttons are responding, not even to turn of power. Cannot access menu as I have blank,...

Hi Cat, You can try removing the data cable of your monitor, the one connecting to the back of the tower/computer. If there are no issues on the monitor, normally you will be getting the power self test which is indicated by three vertical colors on the screen (Red, BLue, Green). If you dont see the power self test, it may be a problem with the monitor. YOu may want to try using a different monitor to isolate issue if available

I have a brand new shiny benq v2210 but no drivers or install disk. How do I install it. t thanks

I just went to the BenQ website and found the following:

Please visit the BenQ website at to download the appropriate LCD Monitor drivers, alternatively you can also use the standard plug n play monitor driver in windows.

First I did Google search for BenQ
> clicked on support
> chose USA
> Knowledge base
> FAQ LCD Monitors
> first question: I don't have the driver for my LCD monitor, what should I do?

Also, I found the BenQ phone number (1. 866. 600.2367) that you can call during Monday to Friday business hours which are: 8:30 to 5:30 PST

I hope this will help resolve this for you

15 inch lcd monitor Benq Model Q5T3 has a blank screen has power but screen just black. Can let it sit for a while and sometimes it will stay on for a few minutes but goes black again Thanks

It could either be a driver issue on your system, or a problem with your video card. Turn off the computer, open the case, remove the video card, re-seat it in the slot securely, close up the system and power it back on. If the problem still happens, update the display adapter driver, if it still happens, try a different video card or monitor. You could even test your monitor by plugging it into a system that you know doesn't have this issue.

Hummm. Try to unplug everything, reconnect, than restart. If not working, try to plug your monitor on a different computer to diagnose what is wrong, the computer or monitor. It could also be your graphic adapter, verify that it is firmly attached to the motherboard.
Lastly, replace the defective part.

Unexplained Blank screen.

Looks like your Power Supply has gone Kaput .. Usually it is the Electrolytic Capacitors on the Power Supply Board, try a new one, or replace ALL the Electros with same or better ones.
