My Problem Isn’t Described Here !
While we have tried to make this manual as complete as possible and
include as much troubleshooting help as we can, there will still be some problems
which haven’t been foreseen or are so rare as to not be included.
Some tips:
•
Always begin by reading the Theory of Operation and review the Signal
Lists. By understanding what the unit is supposed to be doing and how the
circuit boards communicate, you can usually probe some of the signals and/or
swap some boards and determine the source of the problem.
•
Observe the unit’s operation and find as many details of the problem as
possible, such as the mode it occurs in, settings, etc.
•
Is the problem repeatable or intermittent?
•
Consider parts that may wear as more likely to fail.
•
Examine the circuit boards carefully for signs of failed components such
as oily residue underneath an electrolytic capacitor, charred or broken
components.
•
Replace the complete circuit board, do not attempt to repair it.
