Most laptops...if not all have a back light but its more likely to be the inverter board that's packed up. What model of acer do you have ?

Thanks, does this unit have a backlight, and if so, can this be the problem?

it would appear that the inverter has died in the laptop. u need to buy a new inverter - but fitting it can be tricky. most inverters are in the screen part of the laptop.

The screen inverter has packed up...this is a fairly common problem with laptops...its a fairly straight forward fix if you know what you are doing...inverters can be had cheaply on ebay...or once you have a replacement inverter you could take it to a local repair place...
