Re: 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. =)

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.

This tends to be a power issue and monitor is hopefully under warranty and will need to be sent back. Otherwise it is pretty much done.

Power not on, power button blinks green power light, doesn't power up. Benq FP92W

It sounds like you have a power supply problem and the safety shutdown has kicked in, the system will need to be checked by a computer tech with an estimate in mind.

Benq FP92W monitor. The screen has turned white, I've turned it on and off several times but keeps showing a fully white screen. Help?

This isn't an easy solution, my friend. Go to this website and read what so many others are saying about the same problem. When you ger to this webpage, go to the link for the white screen problem, it's the same one you're having.
I wish I could give you a simple solution, but there isn't one, sorry. These days it's usually cheaper to replace than fix, unless you get lucky.

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.
