16x2 lcd Screen turns off my Raspberry Pi

Thu Sep 15, 2016 5:27 am

Hi. I have had a raspberry pi for awhile but never relay used it for anything until now when I decided to use it for bitcoin mining. I fallowed this how to ---> https://learn.adafruit.com/piminer-rasp ... d-assembly to the T. But when I got to the part to attach my LCD screen to my pi, it turns off my pi and it won't turn on until I detach the LCD screen. Any suggestion?

What spec is your power supply? It might not have enough to power the LCD and backlight. Another possibility is a short on the PCB somewhere.

is your LCD plate making contact with the USB?

the adafruit page shows this warning:
WARNING: The new Raspberry Pi model B+ with 4 USB ports overlaps closely with backlight resistor leads on the char LCD plate. You will need to cover the USB port and back of resistors with electrical tape to protect them from touching. See more details and pictures on the assembly page of this guide.

No it doesn't. I have an older Pi that has 2 usb ports. It turns off when I barely put the LCD on the pins.
