And of course, blow the dust out of the connector! https://devblogs.microsoft.com/oldnewthing/20040303-00/?p=40423 https://devblogs.microsoft.com/oldnewthing/20040303-00/?p=40... I was also the family "TV tube test person" as a kid. I must have been around 6 or 7. For the young'uns, TV sets used to have tubes and hand-soldered point-to-point circuitry. Just like an ENIAC, a tube TV would always "go on the fritz" as the tubes burned out. My dad showed me how to pull out all the tubes, and we would put them in a cigar box and go to the little corner grocery, which had a tube tester in front. I would dial up all the settings for each tube and test it, and we would buy replacements for the bad ones. Take them back home and I would plug them in, and the TV worked again! Dad was always generous and made sure I got credit for it. BTW did you ever get to discharge the high voltage connection to the picture tube with a screwdriver and wire with alligator clips? One clip to chassis ground, the other to the screwdriver, then slip the screwdriver under the rubber insulated connector, and BANG! https://en.wikipedia.org/wiki/ENIAC https://en.wikipedia.org/wiki/ENIAC https://en.wikipedia.org/wiki/Vacuum_tube https://en.wikipedia.org/wiki/Vacuum_tube
