It's normally failed solder joints in the backlight inverter. Is it out of warranty? BenQ carry 3 years guarantee in Australia.

The power board design in that model series usually damages some of the inverter transistors whan that happens - it's not a difficult repair, but in Aus at least the cost of a new power board is low enough that it's simplest to just replace the board.
