Backlight of iBook G3 broken

Hello,

where can i get the background light tube for an 11 years old iBook G3 MyFamily M2453? Is it possible to replace it?

i read that the hardware service for this iBook is discontinued, does this mean that the only way would be, i need to find an other iBook like mine and change the backlight?

The iBook (64 MB RAM, 3 GB HDD) is still working, but the screen is dark and the icons are nearly invisible.

Thank you,

regards, franc
