7) Check if the Draw-connector harness is correct. Check its color.
8) Check if 2 thermistor connectors are connected properly.
9) Measure the Thermistor resistance value from the center and both sides. Check if it has the continuity. (3 Red Circles)
10)Check if the thermistor connector on the main board is connected properly.
11) Check if the FDB connector is connected properly.
12)Check if the voltage in user environment is in this range (80V ~ 140V, 160V ~ 260V).
13)If there is no problems for above steps, update the firmware.
14)Replace the FDB(JC44-00204A(220V)/JC44-00203A(110V)). If the problem persists, replace the SMPS(JC44-00092C(220V)/JC44-00091C(110V)) If the problem persists, replace the main board.
