First of all, to service these, you will need the proper service manuals, at
least a discent DVM, and you WILL have to apply power to verify the voltage
readings in order to determine the fault areas. As for tracing out signal
paths, and etc, an oscilloscope will be necessary.

Correct, except that in many cases an experienced technician won't
require a manual, especially for a generic fault. In my opinion,
having to troubleshoot these problems with no power applied is
ridiculous. The IT approach to electronics troubleshooting?
