I bought it about a year ago and a few days ago I plugged it into my Mac with a micro USB. I did make the mistake of plugging into the USB port initially but it did respond.
For a while it worked i:e the LED lite up. However, when I connected a HDMI cable, the LED went out.
Since then there has been no sign of life. I did not smell anything burning from the Pi.
Have I managed to brick my Pi and if so is there any possibility of repairing it?
