I have rebuilt many myself. They usually contain off the shelf components and are generally very "low tech". The biggest problem that I have seen is the fact that they use single sidded printed circuit boards. Vibration usually causes the solder joints to fail on the heavier components on the board such as relays and the like. Usually a good re-soldering will solve most of the problems. If they would have plated the thru holes the reliability and long term life of MB electronice would be much better.

Pop it open and have a look, you have nothing to loose.
