Cause: The power module is faulty, for example, the power adapter is damaged or the internal power circuit is abnormal. As a result, the device cannot start properly.
Fault point: The measurement value is inaccurate
Cause analysis: Test circuit failure, such as related components damage, poor connection or aging; It is also possible that calibration data is missing or abnormal, resulting in inaccurate test results. In addition, the voltage at both ends of the measured part is different from the set value, or the voltage division effect generated by the output resistance in series with the measured part may also lead to deviation of the measured value.
Fault point: abnormal display (such as black screen, flower screen)
Cause: The display module is damaged or the cable between the display panel and the mainboard is abnormal. As a result, information cannot be displayed normally.
Fault point: No response of the button or knob
Cause analysis: The control circuit of the key and knob is faulty, or the internal connection line is loose and broken, resulting in failure to receive user instructions.
