1.Case of relay fail after supplying AC power
1) Supply to AC power after removing the P811 or P812 Connector.
2) If the relay is connected properly, make sure the output
3) At that time, PSU output Voltage is normal, maybe this problem is Module
4) If relay is fail, supply to AC power after removing the P813 Connector
5) At that time, PSU output Voltage is normal, maybe this problem is Main board.
6) If relay is fail when you can remove all(P811,P812,P814) , maybe this problem is PSU
2) If the relay is connected properly, make sure the output
3) At that time, PSU output Voltage is normal, maybe this problem is Module
4) If relay is fail, supply to AC power after removing the P813 Connector
5) At that time, PSU output Voltage is normal, maybe this problem is Main board.
6) If relay is fail when you can remove all(P811,P812,P814) , maybe this problem is PSU
2. Case of no picture after connecting relay
1) Check the output voltage(P811,P812,P814).
2) If output voltage is abnormal, this problem is PSU
2) If output voltage is abnormal, this problem is PSU
3.Trouble Shooting
1) Check the waveform(P813 #8 pin_error_DET)
2) Check the problem refer to below table)
