Troubleshooting is a lot like taking a test - there is a problem that needs to be solved, and you are "graded" on the speed and success with which you solve that problem. As with any test, a certain amount of preparation is required, and you often have to make some basic assumptions about the problem in order to solve it. unfortunately, many less-experienced technicians are quick to jump at a solution without performing essential checks and observations. Too often, this results in lost time and wasted materials. this chapter presents you with a set of checklists and guidelines that can help to speed your diagnosis of a problem and keep your troubleshooting on track.
