Can you get a voltage reading at the 5V power wire to the LCD? Pin 2 I think. That would at least tell you if you have any voltage issues. Mine would act up with anything below 4.9 volts and sometimes would show blocks on the screen, or clear itself, or restart, or lock up. I have read of quite a few others showing just blocks on the screen, for various reasons.
