Here are some suggested steps to resolve it:
1 Check the power supply**: Servo circuits usually require a stable power supply**. Check whether the power supply circuit is normal and ensure that a stable voltage is provided to the servo circuit.
2. Check the motor drive: The servo circuit usually includes a motor drive part, which is used to control the rotation of the disc. Check whether the motor drive circuit is working properly, including the drive chip, the motor itself, and related connections.
3. Check the positioning of the bald head: The servo circuit is also responsible for controlling the positioning of the bald head. Check whether the bald head positioning circuit is normal, including the bald head driver and associated sensors.
4Use an oscilloscope or multimeter: Use test tools such as an oscilloscope or multimeter to perform voltage and waveform tests on the key points of the servo circuit in order to locate the fault more accurately.
5. Replace damaged components: If you find that there are damaged components in the servo circuit, such as capacitors, resistors, transistors, etc., you can try to replace these components.
6. Seek professional help: If you are not familiar with electronic maintenance, or the servo circuit problem is more complicated, it is recommended that you seek the help of professional Yuesheng audio maintenance personnel. Problems can be diagnosed more accurately and solutions can be provided.
Before proceeding with the repair, make sure that you have backed up your important data and understand the possible risks during the repair process. When repairing, you should follow the relevant safety operation procedures to ensure your own safety.
