belongs as recorded above.
C) Turn the machine on (fan running)!

E) Re-measure +12 and / or +5 volts (within range now?). If the symptom was intermittent call
debug screen 1 to watch 5V Est and / or 12V Est. Allowing sufficient time, does the
symptom you were troubleshooting reoccur?
Yes Symptom reoccurs! The last device plugged in (or its cable) may be causing the
problem!
No Screen on and/or good voltage(s)! Repeat parts a through e until a cable is plugged
in and the symptom reoccurs indicating the last device plugged in (or its cable) is
causing the problem! If after ALL cables are plugged in AND the problem does not
reoccur either it is very intermittent or reseating a connector solved the problem.
