Sounds like googling for Yamaha SY77 display upgrade gives a lot of
good options.

I've seen many cheaper LCD options compared to the Optrex DMF5005 or
Futurlec, but they all use other controllers and a slightly different
pinout as well.
So far the DMF5005 and Futurlec(unknown model) displays use the same
pinout as the original module.

The replacement LCD modules might need replacement contrast resistors
as I can see, and the LED-backlit LCDs are thicker than the original
unit it would seem. That isn't a problem for the K5, but what about
the K5m?

One other problem for some might be the 20-pin ribbon cable. The
original connector is crimped to the cable and soldered on the module,
so it's going to be a pain to remove if all you have is a soldering
iron + desoldering pump. A 20-pin ribbon cable + a cheap 20-pin male
header are quite easy to find online though.
