Check points
Is the power cord plugged in an appropri-
ate outlet (of the correct voltage)?
Are the connections secure between the
LVPS (CN1) and the Mother PBA (CN1),
between the Mother PBA (CN24) and the
Main PBA (CN12)?
Are the rated voltages being output from
the LVPS?
When no problem is found in all the steps
above, the PBA's may be defective.
Solutions
Plug the power cord in an appropriate out-
let.
Connect each PBA firmly.
Measure the voltages between the follow-
ing pins of the LVPS (CN1). When the rated
voltage is not measured, replace the LVPS.
Replace in the order of: Main PBA, Mother
PBA.
