I just started hooking up the LCD and noticed some problems. I have pin 1 to 5V and 2 to ground. I then hooked up 8.5 to pin three for the LCD power. Nothing comes up and my 5V power supply pulls up to about 7.5V and the 8.5V source drops to 7.5V. I think also noticed that the LCD comes on with only pins one and two hooked up. Am I doing something wrong? Also, from reading on the side the last two pins are used for the LED backlight correct? Thank you for the help!
