The speakers on my ES920/ES520 digital piano have stopped producing sound — what should I do?
Check volume and mute settings first. If no output through any connection, contact a Kawai service centre.
If your ES920 or ES520 has no speaker sound, work through the following steps: First, confirm the master volume is not set to zero. Second, verify the internal speakers are not muted in the settings menu. Third, test with headphones to isolate whether the issue is with the speakers specifically or with audio output in general.
If headphones produce sound but speakers do not, the speaker output may be disabled in settings — consult your manual for the speaker/headphone output configuration option. If no sound is produced through any output including headphones, try a factory reset (consult your manual for the exact procedure).
If the problem persists after these steps, contact your local Kawai authorised service centre for evaluation and repair.
