No Display Trouble Isolation

No Display Trouble Isolation
This trouble isolation procedure helps isolate a problem to the assembly level when there is no
display on the flat-panel liquid crystal display screen.
A
Remove the cabinet and install the fan safety shield.
1 Disconnect the power cord from the oscilloscope. See Chapter 6, “Replacing
Assemblies,” for instructions on removing the cabinet. Use care in handling the
oscilloscope.
2 Install the optional fan safety shield, Agilent Technologies P/N 54810-00601, over the fans
on the left side of the oscilloscope.
WARNING SHOCK HAZARD!
The backlight inverter assembly, which is mounted at the front corner of the oscilloscope near
the flat-panel display, operates at 900 V at turn on. DO NOT handle this assembly while it is in
operation.
WARNING INJURY CAN RESULT!
Once the cover is removed, the fan blades are exposed both inside and outside the chassis.
Disconnect the power cable before working around the fan. Use extreme caution in working with
the oscilloscope when the cover is removed. Install the fan safety shield (Agilent Technologies
P/N 54810-00601) on the side of the chassis over the fan. Failure to observe these precautions
may result in injury.
B
Check the fan connections.
Verify that all fans are connected.
1 The oscilloscope fans connect to the fan controller board on the bottom deck A20.
2 The CPU fan connects to the top side of the motherboard noted “CPU Fan.”
3 The Power Supply fan is at the rear of the power supply.
4 Connect the power cord and press the power switch on the front panel. Verify that all
fans are running and that the front panel power switch LED is illuminated. These are
indications that the power supply is functioning. If the fans and LED are off, go to the
Power Supply Trouble Isolation flowchart. Otherwise go to step C.
C
Connect an external monitor, cycle power, and observe the following oscilloscope
power-on sequence. If the power-up on external monitor test fails go to step D.
D Replace Display Card (Agilent Technologies P/N 0960-2530). If the display is still having
problems go to step E.
E Replace the motherboard assembly A19.
