6. If the value in the VL field correct, but you continue to get a 0-60-n fault code, do the following:
a. Do a check for a short-circuited
fan. Disconnect the fan from the
power PCB, as follows:
 J3 in Powermax65/85 SYNC
CSA models
 J5 in Powermax65/85 SYNC
CE/CCC models
 J1 in all Powermax105 SYNC
models

Another possible indication of
a short-circuited fan is when nothing shows on the LCD screen after the
plasma power supply is set to ON (I).
b. With the fan disconnected, does the problem go away?
 If yes, replace the fan.
 If no, perform the steps in Test 5 – Flyback circuit (DC minor voltages) on page 94 that
are related to the fan. If the problem continues, examine the DSP PCB.
c. Disconnect the DSP PCB from the power PCB. Carefully remove the conformal coating
from the pins, if necessary. Too much of this coating can prevent a good connection with the
power PCB.
d. If the problem continues, replace the DSP PCB.
e. If the problem continues after a new DSP PCB is installed, replace the power PCB.
For all CSA models, and for Powermax105 SYNC 230 V – 400 V CE models, also replace
the PFC IGBT module.
