    Make sure that you have a 100 to 330 ohm resister in series with the LCD backlight. Some of the documentation is not clear on this, but the resister must be there or the LED backlight will act like a dead short as soon as the voltage rises above the LED forward bias - usually about 2.0V.

No public wish lists :(
