Mine had a similar problem. Try shining a light on the display and seeif you can see (very very faintly) the BENQ logo when you turn it on.If you can, what you will probably need is this:

The description says that it is for Dell and HP monitors but I thinkthey use very similar components. In my case I only had to replace theBel 3a ms125v fuse and it's working perfectly now.

Sorry if you don't like eBay, but that was the only place that I could find those parts and the seller seems really helpful.

The problem is something to do with the circuit board. Its the inverter cicuit that has one or couple of components faulty. I susgest you bring it o the repair shop. If you know how to check transistor II susgest you trouble shoot in the inverter circuit, there should be a transistor with a similar value to this (C5707) there you'll see two identical circuits. Check the transistors.

Black out problem


Try a different known working monitor and hook it up to the computer. Turn on the computer and the monitor and see if you can get video. If you get video then you know the original monitor is bad.

If with the known good working monitor you still don't get video then you know its something either with the video card or the motherboard if you have integrated video.

Monitor displays breifly then goes to blank screen


The green power light indicates that the monitor is receiving from the computer correctly. I suspect it is going into high voltage shutdown. There is a safety circuit that monitors the high voltage and shuts the monitor down if it sees anything amiss. So the monitor comes on and then shuts off. High voltage problems are generally not worth trying to repair. Another example of a worthless safety feature. High voltage failures are not dangerous, and adding the safety circuit just kills the unit when it may have some life left or worse, sometimes it is the shutdown circuit itself which fails!
Hope this helps.

Blank Screen Now.


Backlight is torched, it happens without warning. These can be repaired, but finding the appropriate backlights, and trying to get this thing apart is a royal pain in the you know what! But your backlight has burned out! Sorry!

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.
