Potentiometers

There are 4 potentiometers that stick out from the top of the motherboard toward the DC adapter port.
It is possible to replace these potentiometers by re-soldering their connection points on the back of the motherboard.
If you have resoldered the electrical connections and are sure the pots are still not functioning or "Noisy" and are destined for the e-trash, the safest way to remove without damaging the main board is to cut the the solder lugs one by one with a small wire cutter. Remove the complete pot mechanism—note: the values normally printed on the pot.
From the solder side: Heat the lugs one by one - With the soldered side facing up, as you heat each leg and it is molten - give the board a jolt and they will fall downward. Repeat one by one until they're all out.
They are hot, be careful of the surface they will fall onto.
The plated through holes for the component ALL need to be cleared of solder to enable the new component to be uniformly fitted through the holes
Plated through holes(PTH) can be de soldered with a hand held vacuum de solder tool or copper braided wick
Do the hard work now so you can just "plug and play" the new components when they arrive
