Notes for repairing chair or replacing parts:
①Make sure the power is OFF before tearing down the wires, moving terminals or replacing
parts.
②Semiconductors (such as IC and others) are very easy to be damaged by static, so when you
touch the PCB, please make sure your body is grounding (by wearing a girding static ring), or
your hands are touching with earthing grip (household electrical appliances putting to earth, such
as fridges, washers and so on) to release all static of the body.
