Those things (the LF13331's) are on the top of my "Most likely to die" list.

The last time I looked Digikey claimed to have 600+ instock, I bought 10 so
make that 590+. The're $5.35 a piece but if you have as many of these
monitors as I do it's not so bad of an insurance policy.

Cinematronics did have a replacement for this part since even at the time of
manufactoring they were hard to come by. It required a daughter board, but
according to a tech "he thinks" it was to drop some voltages, and change
pinouts. None of this does anyone any good just yet, because I can't
remember the name of the part. (I can get the name.)

Either way I saw that there is a description of the circuit on that
StarTech(or something) CD they want $300 or $400 dollars for...

All said and done if you're re-designing the board this should be an easy
part to replace, (I wouldn't use either of the above) it just needs to
switch positive and negative voltages. The current handling is not great,
and can easily be calculated (I would if I had a schematic here in front of me).
