Troubleshooting:
General Fault Isolation
Visual Inspection
A thorough visual inspection of the equipment can save time. Small
things—disconnected cables, foreign debris on circuit boards, missing
hardware, loose components—can frequently cause symptoms and
equipment failures that may appear to be unrelated and difficult to
track.
NOTE
Take the time to make all the recommended visual checks before
starting any detailed troubleshooting procedures.

Power Source
Faulty wiring, especially AC outlet
Circuit not dedicated to system
(Power source problems can cause static discharge, resetting problems, and noise.)
