Repair guide: TMA-2 speaker units

Repairment is an essential part of our collective mission to do things better and protect the environment. Raw materials used in electronics are becoming increasingly scarce, and at the same time waste from obsolete electronics are growing into a bigger and bigger problem every day. It is essential that we make an effort to reuse what we already have and thereby increase the lifetime of every product.

TOOLS

All you need is a small cross head screwdriver. We use a Phillips 00.

DISASSEMBLY

  • Remove all 4 screws in the speaker plate
  • Carefully take out the speaker plate
  • Remove all 4 screws from the pin plate
  • Take out the pin plate
  • Take out the spring and the pin
  • Remove the tunnel - they are press fitted, so carefully press the outside of the tunnel to take it out
  • Remove the second tunnel

SPEAKER UNIT DISASSEMBLED

TROUBLESHOOTING: NO AUDIO

When disassembled check all the wires. Are they all soldered firmly in place on the jack sockets and speaker driver. If not they can easily be soldered back in place.

TROUBLESHOOTING: PIN MECHANISM

If the pin is not working as intended it often helps to disassemble everything and assemble it again. Make sure that the spring is inserted correctly inside the pin and aligns with the pin plate. If that does not work then either the pin or spring needs to be replaced.
