iMac G5 (20-inch iSight) Troubleshooting — Symptom Charts 150
Plug the power cord into the iMac G5 and into the AC outlet. Check to see if diagnostic LED 7.
#1 is On or O.
LED #1 is On: This indicates that the AC power inlet and AC-to-DC power supply is getting
good power from the AC outlet, and the DC-to-DC board is receiving 12VDC. Go to step 8.
LED #1 is O: Inspect for loose or disconnected cables. If cables are connected, your AC-to-
DC power supply or AC power inlet may need to be replaced. Since power inlets rarely fail,
replace the power supply rst and retest for system power. If the symptom persists, replace
the power inlet.
