Fixing the Hanns-G
In Server Room 1, I have a Raspberry Pi 4, which I use as a general purpose terminal. The screen is a beautiful 27 inch monitor, 2560 by 1440 pixels, which means I can have several terminals running at once. I got it second hand on eBay for a very low cost.
A couple of days ago, I powered it on, and nothing happened. Then I noticed that one of the breakers had tripped, so I reset it ... still nothing. And there was no little green light on the power brick. When I tested it, it was dead, and that explained everything. The power brick had shorted, and tripped the breaker.
So I needed a new Hanns-G power brick. I went onto eBay and ... nothing. This thing was just too old and unusual for spare parts to exist. But the old brick told me that it wanted 19 volts, 3 amps. So I went back to eBay, and bought a generic power brick, 19 volts and 3 amps, for £11.
It arrived today. The unit didn't have the output voltage engraved on it, but I checked with a voltmeter, and it was indeed 19 volts. But the plug to the monitor was the wrong size. Nothing is ever easy.
Never mind - I had one that was the right size. I cut the lead off the old power supply and spliced it onto the new one, plugged it into the monitor and it immediately came to life!
A replacement second hand monitor would have cost about £60
Meanwhile, Server Room 2 is starting to take shape.
