The 8mm video cameras were the most amazing combination of mechanics and electronics, all ready to take a dump in a moment. I have 2 sonys that stopped working. Found a website on just how to whack it againt a table or hit it with a mallet - and about 1000 posts saying it works, including the techs that worked on them - they did it and charged 100$.
I found the safer way to touch a little spring and cog with a pencil to make it work another 4 hours. In a pinch, A good slap does work. My Kodak Retina3c from 1956 still takes better pictures, and except for the bellows, will last forever.
Anything run by a chip can be programmed to die right on time to keep the company profit up. Unless you are an electro-nerd with endless free time, we have lost control over most devices in our house.
We have acompany here deep in the woods that makes NASA pressure transducers. Those I could trust. The ones from back alley wongdong-whoa-to you LLC, are sabotage.
