I had a problem that I figured out the solution to and put up a video of it that made me a few dollars a month. Then YouTube moved the goalposts and demonetized it because I don’t (and frankly, won’t) have 1000 subscribers.
So that’s the end of my video posting on YouTube. I’ve discovered some “hack” repairs to other devices (common washing machine and MacBook speaker issues), but you won’t see my solutions on YouTube, just 99 videos saying to replace it or fumbling with software settings that aren’t the problem.
