I've just received my CFA634-YMC-KS LCD. I applied +5v to the +5 (lcd) pad and a ground. The lcd booted up with the crystalfontz boot screen. I then applied +5v to the (led) pad and the backlight turned on as well.
after a few tests of this (power up/power down), the backlight comes on, but the crystalfontz boot screen does not any longer, all i get now is an lcd full of '}' characters.
Any ideas on what might be the problem? I have double checked voltage at +5v and ground is secure.
Also, I have shorted JPA in preparation of using this via spi
