Try resetting PRAM; at startup press command+option+P+R until you hear a second boot chime then release. If that doesn’t help it might be you have a faulty keyboard or a faulty backlight circuit, but unfortunately there’s no way to tell exactly which of the two without some basic logic board testing.

Most likely the CCFL's and/or the inverter are worn out
