The backlight must have a current limiting resistor installed. Please see this thread (http://www.crystalfontz.com/forum/showthread.php?threadid=62) for instructions on how to calculate Rlimit.

There is schematic in this post (http://www.crystalfontz.com/forum/showthread.php?threadid=319) that shows the connection of Rlimit.

High current through the backlight can damage the backlight as well as causing too much heat.
