Use care not to short adjacent voltage test points.
If the voltage is correct, replace the system board assembly. If the
voltage is incorrect, go to step 4.

System board
Check to make sure the LVPS cable is correctly installed at J27 on
the system board. If not, reseat and recheck the voltage at the
+5 V dc test point on the system board.
If test point does not m5 V dc, go to step 5.

LVPS
Unplug the AC line cord from the LVPS and disconnect the LVPS
cable to the system board. Reconnect the AC line cord and measure
the voltage on CN2-1 on the LVPS. The voltage should measure
approxi5 V dc.
If the voltage is correct, go to step 6. If the voltage is incorrect,
replace the LVPS assembly. See
“Low voltage power supply
removal” on page 4-54
