It will run forever at nominal conditions without a stimulus of some sort (or 2 years of thermal expansion and contraction if it survives the postal service). But if you catch that sucker smouldering, it can be tightened and good forever.

People running sane burn in programs include some form of shock, from whacking with rubber mallets to vibrating the product in patterns. They usually ensure the burn in includes at least some temperature variation as well. However, some people think production testing is about cosseting a product, so the flaws don't show up. Fire them. :)

I am curious about burn in on CRT tv's. Did they do it? It has a sane component count. Since the phosphors is just a canvas, and the beam steering does the work, so its just a few very nice amplifiers.

The Japanese started burn in for TVs and other consumer electronics in the 1970s. When they started building in European factories, and arranging JVs with existing European makers to build in European factories, the practice spread. People found there were financial improvements from the lower level of warranty claims.
