A7 Midplane Board +5.1VSB LED
Is the +5.1VSB LED on the A7 Midplane board on?
If yes:
After verifying that the connections from the yellow front panel Standby
LED back to the A4 Processor board are not at fault, replace the A4
Processor board.
If not:
Replace the A6 Power Supply assembly.
Most DC power supplies come from the A6 Power Supply assembly.
However, the most convenient measurement location for all the DC
supplies is the A7 Midplane. All power supply LED's are accessible once
the instrument cover has been removed.
Before replacing the power supply, verify the midplane and motherboard
interconnects are mechanically secure.
