Common Keyboard Problems We Repair

  • One or more keys silent — a cracked or dirty rubber contact pad beneath the key, or a failed key contact strip.
  • Keys stuck or slow to return — worn key pivot bushings or debris under the key.
  • Distorted or weak audio output — a failing amplifier IC or a blown speaker.
  • No power — a failed DC adapter, a blown internal fuse, or a damaged power board.
  • Display not working — a cracked LCD module or a failed display driver IC.
  • MIDI not transmitting — a faulty MIDI DIN connector or a damaged USB MIDI chip.
  • Sustain pedal input not working — a broken tip connector on the pedal jack socket.
  • Pitch/modulation wheel not responding — a corroded potentiometer inside the wheel assembly.

Keyboard Repair Services

Key Contact & Mechanism Repair

We clean or replace carbon contact strips, rubber pads, and key pivot rails. For weighted-action digital pianos, we replace broken hammer assemblies.

Power Supply Repair

We replace blown fuses, failed bridge rectifiers, and faulty voltage regulators on internal PSU boards.

Audio System Repair

Speaker cone re-foaming or replacement, amplifier IC replacement, and headphone socket repair.

Display & Interface Repair

LCD replacement, encoder knob repair, and button membrane replacement.

Full Board-Level Diagnostics

For complex failures, we trace faults at component level using oscilloscope and multimeter — more cost-effective than replacing the whole instrument.
