All cables tested and work:

SCL - A5
SDA - A4
VCC - 5V
GND - GND

I'm using an Arduino Nano board and an I²C display - I've tried everything to get it to work and I'm now convinced it's a hardware fault. Using the Arduino I²C address scanner, it is unable to find a device, even though it is wired correctly (I've checked multiple times).

This is the code I used, i2c_scanner, and this output:

Scanning...

... is all I get.

Any suggestions, or is my board output fried?
