    Please help with noisy motor in turntable

    I've got a cheap turntable that is having noise interjected into the audio output from the motor. I'd like to "fix" it rather than throw it out. The turntable has a small, one board design that contains all the circuitry, including a usb audio output. It has a volume knob/power switch. After being powered on, there is no noise until the tonearm is moved over and the motor starts. There is a low level static noise interjected into the audio output. If you put a strain on the motor, the pitch of the noise gets higher. Any ideas based on the photos? I'm an amatuer, btw

    Follow the motor wires to the board or if goes to a connector see if there is a capacitor on the board or on the back of the motor replace it

    If this does not eliminate the noise then look at the wires on the tone arm for broken wires including the shield wire for a bad connection
