[QUOTE="Mur Huwcun, post: 7173045, member: 33114"] Have a childrens soft toy here that plays different song lyrics. It recently stopped working so ordered a new speaker for it. Unfortunately it’s still silent!! Had a look at the PCB, it’s got battery voltage, continuity for the speaker wires and every coloured pair is wired to a different switch for a different lyric. One of each pair is live and the other is energised by pressing the switch. Is anyone in the know about these things and if there’s anything else that I can do or test?
