Where displayed Possible Cause or Repair Action
UI Display & CN8 Check Fan operates by inspection
Ctrl PCB when D90 is on, during output cur-
rent load condition, Check CN19.6
is low when system is cool. Check
temp sensor connectors on power
pcb CN5, CN6, CN7 & CN8. Check
Optical sensor power pcb U12.
Operate the system at the specified
duty cycle.
UI Display & CN8 Check across C64 at room tempera-
Ctrl PCB ture it should be ~1.0vdc. When
system is hot it will reduce to a trip
point of 157mV. Input from power
pcb is CN19.3. Check power pcb
CN9 or Output Diode pcb CN3 for
connection
UI Display & CN8 Faulty Power PCB, Bad PFC, Inverter
Ctrl PCB, , D43 or Bus Caps. Less likely but also
Ctrl PCB on=fault possible bad PFC inductor or Main
Transformer.
UI CN1 connection on Ctrl pcb, Bad
Display,Console, OKC connection internally between
CN8 Ctrl PCB okc and ctrl pcb , Faulty ctrl pcb.
