Да ну? Уверены, что сможете? ну чините, только обязательно отпишите о результате:
Error code EF: The supplied power is unstable.
Possible causes:
- The irregular power supply is detected. Replace the low voltage power supply PCB ASSY; reset the irregular power supply detection counter.
- Main PCB failure. Replace the main PCB ASSY.
Note: The irregular power supply detection error (Machine Error EF) occurs when there is a large fluctuation in the power supply voltage supplied to the machine.
In this case, if the same power supply is used, the same error might occur again even if the low voltage power supply PCB ASSY is replaced.
