You may need to remove the PCB to facilitate easier access to various components.

Remove any screws holding the PCB to the chassis, plinth, or to any heat sinks that would restrict removal.

Disconnect any cables from the control PCB to other parts of the turntable such as the speed selector switch and power supply. On some models, such as this Technics, you may need to cut the wires if no connectors are used.

You can now rotate or remove the PCB.

On many direct drive models, the motor's stator coil is soldered onto the control PCB. The motor's shaft and bearing assembly, along with its back plate may also be held onto the PCB by long screws threaded through the stator assembly. In this case, you can remove the PCB with the shaft and bearing assembly and back plate attached.

Power supply filter capacitors on the control PCB may be holding voltages around 20-30V.
