I wish this were always true. I’ve repaired LED TVs, powered monitors and amps that have blown caps. I’ve not talking about old stuff - I’m talking about equipment that’s 2-3 years old.
Equipment that’s protected with surge protectors or UPS backups rarely have issues like this, especially when they are left on all the time.
Much of the equipment I repaired died on startup, not while running.
The replacement caps were surprisingly cheap - like $5 for 20 OEM caps. Manufacturers could easily make their equipment more robust for only a small investment in components with higher capacities and built-in surge suppression.
