Yamaha clavinova pf p-100 with no sound


(Ann Arbor, MI, USA)

After a move, my yamaha will turn on, but does not make any sound. I saw someone mention doing a factory reset to try to restore sound. How do I do a factory reset?

Alternately, how do I find a reputable person who would repair it despite how old it is?

no sound on grand piano 1 setting
by: Anonymous

During a group rehearsal today, I had no sound UNLESS the damper pedal was held the entire time which of course was then no sustain.

Ugh...After everyone left, I played with the piano sounds. I had sound with Grand Piano 2 and the sustain pedal worked fine.

It's the Grand Piano 1 setting where it doesn't work. Any thoughts on that? I didn't read anyones input about that scenario.

Hopefully, no trouble for a Recital tomorrow!

Clavinola PF100 Headphone plug
by: Damian

Brilliant!! Yes opened up Clav. thinking it may have been glass fuse but no. Hugely expensive to get expert out to fix, found this post, took another look and found headphone plug loose. Now working beautifully. Thank you.
One more small problem though.
Now can't get my 15 year old son off it!!
Any solutions?

Speaker Switch It Was
by: Anonymous

Soooooo glad for forums like this! We just moved an older Clavinova into the house and were dismayed when it didn't work. We turned to Google, and found this post. We easily found the speaker switch under the back section of the keyboard. Voila! Thanks!

Speaker Switch
by: Anonymous

Our Clavinova (CLP 120) has a speaker switch, which we found after we panicked and thought we had fried our piano! It's in a small recessed area under the left end of the keyboard. I had to lay on my back on the floor to look up and find it. Or think of it as above your left knee when playing -- but way over to the left end underneath the lowest notes on the keyboard. It's clearly marked (if you lay on the floor and look up) as "speaker" switch, with positions of on, off, and normal. On and normal work fine. Easy fix!!!

Fix for no sound
by: Tom Campos

When the keyboard is moved the board that makes the headphones & Speakers work, will sometimes get unplugged. This is a simple fix,: Open the keyboard and reconnect the wire that comes out from the back of the headphone logic board to the main unit logic board. Once this is done the speakers and headphones will have sound again.

I do have the same problem no sound on my p-100 and the switch doesn't solve it. There is also no sound on the headphones...

I found the speaker switch on the back. That is exactly what the problem was. Thank you so much for your help!

P-100 with no sound after move
by: Jimmy Smith

You have a switch on the back that cuts off the speaker system. Odds are, you inadvertantly switched it off when you were moving the keyboard. Simply move the switch on the back to the other position and cut on the keyboard. The switch was put there in the event you do not want to use the onboard speakers.
