Troubleshooting Diagnosing A Suspected Hardware Problem - 21
- If the problem persists, repeat steps 2 through 4 (only
once). If a dialog box appears that says the Display
Service Utility (DSU) is unable to communicate with the
display, reassemble the monitor, and return the display
for whole unit or head unit replacement (following the
service strategy in your region).
6 If the Create File process finishes successfully, click Adjust
Geometry. Clicking this button causes the DSU to
automatically verify EHT (high voltage). Use a probe to
measure the high voltage. (Refer to “Checking High Voltage”
in this chapter.)
• If the high voltage is okay, replace the CRT/video board and
adjust the display (see “Adjusting the Display after
Replacing the CRT/Video Board” in this chapter). If the
hardware problem still exists after completing the
adjustments, return the display for whole unit or head
unit replacement (following the service strategy in your
region).
• If there is no high voltage, replace the main deflection
board and adjust the display (see “Adjusting the Display
after Replacing the Main Deflection Board” in this
chapter). If the hardware problem still exists after
completing the adjustments, return the display for whole
unit or head unit replacement (following the service
strategy in your region).
