In my early 20s I had a part-time job as a pizza delivery driver. When there were no deliveries, I would answer phones or take orders at the counter. One day one of the touchscreen monitors at the counter stopped working. It was just black all the time. So we were told not to use it.

A few days later I was on lunch shift and bored, I was trying random things to see if I could fix the monitor. Switched the inputs, switched to a different VGA cable, etc. At one point I discovered the touch panel was still working, I could interact with the OS, even though nothing was displaying. I was pressing around different areas of the screen and I accidentally found that pressing right in the centre of the screen caused the display to re-appear! It would disappear again after a few seconds. Press that spot again, it came back. I was fascinated by this, I showed some coworkers, they didn’t care.

Over the course of the day it was getting harder to make the display re-appear. It gradually needed to be pressed quite forcefully to come back. I stared using my knuckles to knock sharply on the spot, and that was working.

When my manager arrived for the night shift, I was excited to show him my discovery. I said “hey man, I kinda fixed this monitor, watch this!” And I enthusiastically knocked hard on the centre of the screen with my first. The LCD lit up and showed the display, but at the same time shattered in a rainbow ring the shape of my fist.

The look on my manager’s face was of awe and horror. I was trying to explain what I had meant to do, but I realised what it must’ve looked like to him. “Hey man, watch me fix this monitor!” Before smashing the screen with a swift punch. It wasn’t possible to explain it a way that didn’t sound crazy.

In the end I convinced him that the monitor was faulty anyway, and we were going to replace it anyway, so my accident breaking it more is not a big deal.
