This is probably caused by a bad "inverter" board inside the screen housing.Don't worry they are relatively inexpensive and easy to replace.
However, some laptops have a failure on the motherboard which causes the backlight to go out,because the inverter,which powers/controls the backlight,depends on power and a PWM signal from the motherboard.
Backlight problems are almost never caused by the backlight itself.

TREO 90 Backlight


The Treo 90 had a problem with backlight failure, which Handspring acknowledged and began fixing back in 2002.  However, their guideline was that if your 90 did not fail within 6 weeks of use, it did not have the defective part responsible for the failure.
Your backlight probably has just died of old age.  It is EXTREMELY difficult to replace just the backlight (I've tried).  If you search long enough on eBay, though, you can probably find a 90 with a broken case, dead battery, broken motherboard, or some other ailment, but with a functioning screen/keyboard assembly, including backlight.  It's a pretty simple matter to replace the screen/keyboard assembly (there's a screw hidden under the battery that holds it into the front frame).

Palm IIIxe backlight


No, the backlight seems to be about the first thing to go when these screens fail. You can possibly get a replacement screen from pdaparts.com.

If you can see the picture under bright light then suggest you navigate to System->settings->backlight->configure and try to raise the brightness level. Have you tried a hard reset - small slide switch on the bottom edge. If this does not work then the back light or control electronics may well be broken.

Because your screen is broken and that can only be fixed if you have it replaced.
