Not really. Often the value of device greatly exceeds value of work. Also repairs are trivial with some basic skills and equipment. For example replacing capacitors takes 15 minutes and extends life of device by several years.
I myself got into soldering because my laptop broke down. 10 years ago replacement would cost my monthly salary and I had nothing to loose. I practiced a bit on old TVs and after two days I soldered laptop motherboard.
Plus some repairs are really trivial. For example several problems can be 'fixed' by baking electronics in oven. Heat will re-solder some connections and electronics could work for another year or two.
