[sdiy] LCD question

[Gene Stopp]

Yeah I tried to side-light with some rectrangular LED's but that didn't
work. The EL plate provides a wide, even light source. Multiple LED's (if
there were room, which there aint) would make spots of light. There's only a
couple of millimeters of space to work in - I thought about sliding in a
frosted piece of plastic behind, and side-lighting with LED's, but it's
getting to the point of diminishing returns time-wise. I don't really need
it since I have a MidiSport 8 x 8 on the PC, but it's a little too cool to
just junk.

In the one backlight failure I had... it turned out to
be an LED backlight so I was able to repair with SMT
parts...

that NOT being your case... I would try an replace the
backlight or display.  If not, there is a company
called Lumitex that makes fiber-optic backlight
panels.

They are mostly OEM but maybe you could get a sample
and adapt ???  You'd add your own light source like
incandescent, or high brightness LED...
