I had to leave for work and my monitor started to flash different colors. but at the top left of the screen a message appeared.
After I jumpered the picofuse, I noticed that the 2N7000 was running hot. I replaced it with a bs170, (exact replacement). Now the thing works like it's supposed to. After I replace the picofuse, I'll put it back together.

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.

Problem normally is dry solder of power transistors and inverter transformer.Resolder should solve Intermittent or Display switch-off problems.

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!

Green light is on but screen is black, it's even detected by computer, and was installed by Plug N Play. I even tried to make split screen with my other monitor but no help.
