Likeliest is that either the fluorescent lamp or the exciter circuit has
given up the ghost...you can replace the exciter circuit easily, don't even
have to take the LCD out, but I've never looked at the lamps themselves.
Either will swap from the 50. Or you could just swap the whole lid...
(Or you could give it up as a bad job and send me a present of the
wreckage!)
The tubes have a finite life - a few thousand hours - so you're better off
using the auto-off power saver under the hairy lightbulb in windows. The LCD
lasts a lot longer IIRC.
