I know about planned obsolescence, but HOW does it happen? How can a TV mounted on a wall for 3 years up and die all of a sudden? How will a network router suddenly give up the ghost after years of working?

The most common failure points is the solder that connects the different internal pieces of the electronics to each other. After too many heat cycles they can break down and can desolder themselves which effectively breaks an electrical connection. Depending on what solder point breaks it can range from behaving weirdly to outright not turning on.
Another failure point is the integrated chip itself. Inside the chip are tiny transistors and those transistors can go bad.
