FRU
Action
LVPS/HVPS
Verify main power to engine board
With the machine off, unplug the LPS/HVPS cable at J502 on the
controller board. Verify grounds on pins 10, 12, 14, 16 and 18 for
both the cable and the engine board. If any of these grounds are
incorrect, then check the cable for continuity. If the cable fails
continuity, then call the next level of support.
Turn the machine on with the cable still unplugged, and verify the
following on the cable (engine board will not be powered):
• 6, 17, 19 (Pins): +24Vdc
• 1, 3-5, 7, 11, 13, 15 (Pins): +5Vdc
If any of the voltages are incorrect, then replace the LVPS/HVPS
( p.240 "Dead Machine Service Check").
Card Reader Service Check
• The card reader cover will need to be removed, and the op panel keyboard assembly will need to
be removed to verify the cable connections ( p.43 "Card Reader Cable Removal").

Make sure the card reader USB cable plug is properly seated at J2
(controller board).
Try a different USB cable to connect the card reader card to the
controller ( p.43 "Card Reader Cable Removal").
Replace the card reader FRU ( p.42 "Card Reader Removal"). If
this does not fix the problem, replace the controller board ( p.44
"Controller Board Removal").
