A few BenQ models do have occasional backlight failure. The vast majority of "black screen" faults are caused by the backlight inverter. Most models have this integrated in the power supply board. If it's out of warranty (in Australia BenQ carry a 3 year warranty unless they are re-work units), an inverter fault can probably be repaired for about half the cost of a new monitor, or maybe a little less.

I'd check into a monitor, I highly doubt it'll be cheaper to fix it, and it's not exactly a guarantee that it'll work if you do try fixing it.
