Potential Problems During Boot Process
Instrument Cannot Completely Load or Run the Operating
System
A problem of the instrument not loading the operating system can be caused by a
few different things. It could be due to a down power supply, a processor hardware
problem, an instrument boot-up process error, corrupt disk drive, etc.
This procedure assumes that the instrument can get past the Agilent splash screen
at power on. If it doesn't, refer to the
Screen"
section before proceeding.
1. Verify that there are no external USB storage devices connected to the
instrument.
2. Does the instrument get far enough along in the boot process to run the
"Agilent Recovery System"?
If yes:
Run the Agilent Recovery System by referring to the
Process"
section in this chapter. If this does not correct the problem replace
the A5 Disk Drive.
If not:
Replace the A5 Disk Drive.
Troubleshooting a Blank Display
This section is intended to troubleshoot a display system problem that would cause
the internal LCD to be blank. It is assumed that the rest of the instrument is booting
up and functioning properly. To determine if the problem is an internal display
issue only, connect an external VGA monitor to the rear panel display output. If the
rear panel display output is also not working go to the
Displayed"
section in this chapter.
Once it has been determined that the rest of the instrument appears to be
functioning properly there are a few possible problems that could be causing the
display to be blank. They are:
• An LCD Backlight inverter problem
• A video signal path integrity problem
• A video controller / LCD problem
