Trouble In PC Speaker System Solved

By on January 22, 2014








A neighbor of mine phoned me because the SONIC (Amplified Multi-Media Speaker System) 180W (P.M.P.O) 250mA AC 110V SP-3400AUCX of his PC was having problem.

The complaint was he could only hear distortion sound from the PC speaker.


First I removed the cover and cleaned up the potentiometer (variable resistor) with a Castrol spray which has the following features:

  1. Water dispersant.
  2. Penetrant.
  3. Lubricant.


Once done I tested the sound again by turning the potentiometer and there were no more distortion sound.
