Laptop LCD Dead? Or Inverter Board ?

I've had the display section of a laptop apart, and on reassembly the screen
backlight died a few seconds after switching on. A bit of work with a
multimeter has shown that the fuse on the inverter board has blown.

Bypassing the fuse with a piece of wire (temporarily, of course) causes the
backlight to flicker on for a fraction of a second when the laptop is
switched on, then all goes dark again. Obviously something somewhere has
broken, but before I splash out on a new inverter board, is it possible that
it is actually a problem with the backlight itself? Should I instead be
looking to replace the display panel?
