    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

          Pro-Ject Turntable TK30 Debut Carbon Motor IC
          by retel
          If you have a failed motor IC, Type ILA7056B , that's used in these Pro-Ject Turntables it's a clone of a TDA7056B audio IC which is a lot easier to obtain.

          Onkyo TX-SR805 noise in one channel
          by MegaZAC
          Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

          Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

          There's some logic behind it. As soon as I select an input I get only left...

          Nescafe Aeroccino, still fails with new Motor (red flashes only once)
          by juergenb
          Hi,

          i am asking for some Help.
          I have one of these Nescafe Aeroccino (Milk Frother) things with a bad motor.
          The Motor didn´t start anymore and internet is full of users just swapping the motor for a Mabuchi RF-500TB-12560.
          So i got a few of these from Banggood.

          I swapped the motor and now i have a new fault condition.

          In a working Frother you would press the start button, it will light red and work for a few minutes.
          If you press longer it will light blue and just mixup the milk.

          With the new Motor it just starts...

          charnwood w821 mini wood lathe motor problem
          by sbt123
          hi there,im having a look at repairing a wood lathe for my dad,(charnwood w821)the problem is when turning up the variable speed control,the motor starts to stop and start by itself,if i continue to turn up the speed it will trip the mcb in the consumer unit,there is also a slight smell of burning from the speed controll box.,Another strange symptom is the lathe can be unplugged from the mains after switching it off and the motor will spin a couple of times by itself,so far ive put a new speed controll potentiometer on and new motor brushes,ive also tested the motor windings and everything looks...

          Philips HTS8000 home cinema noise problem
          by courtcircuit
          Hello

          I have since a long time a Philips HTS8010S/01 which has been old but was doing the job.

          Since a few days, it starts by making a weird "static" nois when switches on for a few seconds to a minute and then works like a charm.
          Noise loudly outputs from the 3 channels, even if no signal is sent by the controler.DVD to the subwoofer/amp unit.

          I was thinking of a soldering that was starting to be damaged and that was only doing the job after a few seconds of heating, most probbaly on the power board
          Removed each of tyhe boards
