Question about BenQ FP731 17" LCD Monitor
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!
