Power transformers and flybacks are one of the main things other that the CRT that can make or break a TV, and they usually are the hardest to find/aquire/repair/rewind/rebuild. I think all of us who restore and collect TVs want them to operate forever without anything break or fail. But what I'm curious about is if the main reason for failure of flybacks is bad resistors or capacitors. With modern components with almost indefinate lifespans at normal conditions, or atleast conditions seen in a TV, shouldn't a flyback run almost forever? I know heat and age of materials used in flyback construction are factors that can shorten the timespan to failure, but with modern components and normal conditions seen in a TV with adequate protection against line surges and spikes, will a flyback in a properly restored set operate almost indefinately?
