Thanks for answering, but I'm afraid you're
going to do some
explaining. I think backlit screens are the ones who have LEDs or
something else behind, providing light and limiting the visibility
angle, like some of today's LCDs. Non-backlit screens are probably the
kind found on digital clocks and watches. Question is, were
non-backlit LCDs ever used on laptops? And more specifically, on 386
laptops? This one is from 1992 apparently.
Yours is probably backlit. Laptops like the DG/One did not have a
backlight and had to be used in (bright) ambient light.
I'm going to assume that yours has a backlight. These usually take
the form of a cold-cathode fluorescent lamp, or CCFL. These are very
thin, delicate fluorescent lamps and are run from high voltage which
is developed by an inverter module.
To replace a lamp see:

Your Goldnote is mentioned as having a CCFL here:

Inverters tend to be specific to a given laptop model; finding a
replacement can be challenging.
