Power pins not working?

Hello, I just got my arduino today and as a fun starting project I wanted to display some text on an LCD screen that came with the set. Since I'm very beginner with arduino I am probably doing something wrong. I cant seem to get any output voltage from the ''power'' section on my arduino hardware. I'm using the rduino uno. The screen remained black so I tried an LED, didn't work either. Am I doing something wrong or is my arduino broken?

So I fixed the powerpins issue but the LCD screen still won't turn on :frowning:

Without knowing how you have wired the circuit, there is no way of helping.

Give us a clear circuit showing how EVERYTHING is connected.

Hand drawn and photographed is ok.
