Usually an expert would just use a scope to test on certain critical test points in an equipment to determine the fault. Placing the scope on the right point would usually give you an idea whether the circuit is working or is bad. These few critical test points got to be created by you or referring to books that relates to your equipment. If you are particular enough, in fact you can try to create more test points within that circuit. With this way, you will have advantage to solve a problem fast. Creating your own test points need your hard work and it can only be done when you put action into it.
Turn on a working equipment and start to put your scope probe on the appropriate points and record down all the waveforms. It will be worth the time spent on this kind of testing and when there is problem with that equipment, i guess you should have no problem in diagnosing the fault.
