So AU digital clocks have a "calculator" type of LCD screen, rather than a lit up "clock radio" screen? Interesting...
As outback_ute said, a better/working back light is probably the way to go. I had a similar problem with my EB's clock recently.
MR AUII: AU clocks should be interchangable. The real bugger would be figuring out how to take the surroundings out so that you can get to the clock. I'm not familiar with AU dashes though so I won't know where to start. I had to pull half the bloody dash out just to get to my clock.
