Potential Problems During Boot Process

A problem of the instrument hanging at the Keysight splash screen could be
caused by many different things. It could be due to a down power supply, a
processor hardware problem, an instrument boot-up process error, etc.

to
Chapter 18, “Assembly Replacement Procedures”, on page 527

With the AC power applied and the On/Off button turned on, verify that all
of the power supply voltages are at their proper level. This can easily be
done by viewing the power supply LEDs on the back side of the A7
Midplane board. See the
Chapter 12, “Power Supply & Midplane”, on
.
Are all of the power supply voltages at the proper level?
If yes:
After verifying that the connections from the A7 Midplane
board to the A4 Processor board are not at fault, replace
the A4 Processor board.
If not:
After verifying that the connections between the A6 Power
Supply, the A7 Midplane board, and the A8 Motherboard
