Monitor STFC (Self Test Feature Check)
* Turn off the monitor
* Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation
* Unplug the monitor video cable from the back of the computer
* Turn on the monitor
* The floating dialog box should appear on screen against a black background. If the issue appears during the STFC, the monitor is defective. Get it replaced.

Same thing

More Info please, it will usually go to standby if camera turned off or after the meter shuts down after a predetermined time (nikon default setting in camera is usually 6 secs.).
So if you switch camera back on or push shutter release to wake up metering system flash should automatically come out of standby.
Or you can push the on / off button for approx 1 / 2 secs. this will wake it up , then turn it off. Hope this may help Ian

LCD Screen problem

You have a failed inverter circuit. This is a very common fault with BenQ and other LCD monitors. I have seen more FP737 and FP731's and all their cousins in the last 2 years then I care to count.

You will be best to take it to a TV technician and have them do the repair. There are ways to fix it yourself, but the chances of success are not great without a decent amount of electronic knowledge.

Call several places and get approx quotes based on the inverter fault. A lot of TV techs will not work on LCD monitors and is another good reason to call around first.

One final thing, check the manufacture date on the back of the monitor, these normally come with a 3 year warranty and it will be either expired now, or very close to it. If it is still under warranty, then contact BenQ near you to facilitate the repairs.

Benq 24" wont comes back after sleep mode

Try to install the OS once again.
If it turn up the same again then it may be the logical board problem.

Look up the BenQ website.
These monitors have a 3 year warranty in most cases.

Failing that cantact BenQ directly with the phone numbers on that same site.

Malfunctioning monitor (BenQ)

hi, first run the system in safe mode, if that works than u will have to look in for driver problems/settings, sometimes uninstalling the monitor & display driver then reinstalling it back will change the settings to default, try it, let me know

Screen working and after 2 sec screen black

On your power board you will have a faulty surface mount fet with 8 legs that controls the backlights.
There are 4 of these, but if any of them fail the protection circuit turns them all off.
Best best is to get it to a local technician for repair. It is not an easy task unless you have the right equipment.
Hope that helps. =)

The screen is white

This is the internal video card of the monitor.
It has either failed, or the cable that connects it to the LCD panel has come out of either the video card or the panel.

Hope that helps =)
