I long ago gave up trying to be famous in my field, which is consumer electronics. But if I ever am, it will be because of an observation I've made on how things break. This observation has caused a belief I've held for years, and that has been backed up again and again by experience. I have never seen it expressed by anyone else, so to my best knowledge, this is original. Let's call it Spock's Law. Spock's Law: When something breaks, suspect the least expensive component first. If your satellite system stops working, it's a connector or a cable that's the most likely cause. Or it's an inexpensive multiswitch. It's least likely to be the expensive receiver. This also works within a component. If your DVR goes down, it is most likely something inexpensive and mechanical (it's not original to me that mechanical pieces break more often than electronic ones). Even if it is a relatively expensive part within the component, like the hard drive, it is something cheap like a bearing that goes bad. Spock's Law is not limited to electronics. If your vacuum cleaner stops working, it's probably a filter that's plugged. Problems with your car are usually bearings, gaskets, hoses and stuff like that. Rarely does the main computer die. It even works with expensive cars. For all of you who have problems with your Mercedes, it's not with the drive train, which is practically bullet proof. It's the switch that rolls us the passenger window up and down that goes bad. Now, with a Mercedes, it's probably $187 to replace that switch, but you knew that already. It is only an advisory. Spock's Law says the most likely piece to be defective is a cheap one. It is not absolute. Your plasma TV can and will break (see my rant that all machines wear out), but if you lose your picture, the first things to check are your connectors. Spock's Law applies to hardware only. Software is something different. I think it obeys the laws of the Devil. In a recent thread, a guy believes his replacement DVR is bad. I'm trying to convince him it's more likely an optical cable or the optical connection itself. That's Spock's Law. I don't think I'm succeeding, but my forehead is already flat from slamming against brick walls.
