Questions and answers
My Yamaha Electronic Piano powers on and the different tones all light up but there in no sound. What is the issue?
If your Yamaha P-200 powers on and the tones light up but there is no sound, possible issues include:
1. The internal speakers may not be working, but the sound could still come through the headphone or mono output jack.
2. There may be a problem with the jacks or internal connections, even if some parts have already been replaced.
3. The instrument could have a setting issue, such as being in Dual mode or having modified performance parameters.
4. The sustain function may be stuck on, giving the impression of no clear sound.
5. Local Control might be turned off, disabling sound from internal speakers.
Testing with headphones or an external speaker and checking settings may help identify the problem.
