Look at the LCD flex-cable soldering to the PCB, sometimes it isn't soldered well. Also there are often tiny solder balls in between solder pads, that make short-circuit and cause the display to malfunction. But these are rare things anyway...
Also look at the LCD ID and post it here, it's written in the flex cable.
Maybe the firmware I gave you isn't compatible at all.
