My friend who does electronics repair says he's been shotgunning (replacing all of a part, without testing them) Electrolytic caps in transistor radios since the late 1950s. He said it almost always worked.
So, obviously, it's a long standing problem.
- bearjaws 4y agoIt was particularly bad for a few years due to supply chain issues. I worked at BestBuy at that time and it was easily 30% of our workload, computer comes in acting weird, take the side panel off and see a bunch of blown caps. https://en.wikipedia.org/wiki/Capacitor_plague https://en.wikipedia.org/wiki/Capacitor_plague
- Accujack 4y agoElectrolytics have a limited lifespan, that's not due to poor quality like the PCs with caps blowing out. Almost any old electronics will need caps replaced if they haven't already been.
- dghughes 4y agoI worked for my uncle who had arcade games then for a lottery with slot machines. Capacitors always leak I've never seen a device over 40 years where there wasn't a bad cap. At the lottery I had a $5,000 3D multilayered monitor fail. All it needed were 3 SMD caps at maybe 1 cent total parts cost plus labour to fix. the lottery just trashed the monitor instead.
