7.6.4 3D imaging
7.6.4.1 3D sensor is not recognized
• Check the condition of the power feed by following
trouble shooting guide 7.6.3.6 for 3D imaging not
working.
• Replace LVDS data cable from J3208 to the CT-
sensor and reboot the X-ray unit.
If all the LEDs are on and the voltages are OK
and R3220 has been replaced.
 Measure voltage from JG403 (PAN-pow-
er feed).
  If voltages are present, replace
EG400.
  If not, replace CT sensor.
If non or some of LEDs are on, follow the trouble
shooting instructions above.
If any of the indicator LEDs are not on, replace
the board.
If 3D sensor is recognized, cable was faulty.
If it is not recognized, replace R3220 and reboot.
 R3220 was faulty if the sensor is now rec-
