Yamaha Clavinova CLP-115 no sound but lights are on


My Yamaha clp-115 can play the demo songs and the metronome works, but I get nothing from the keyboard. Very frustrating. Any suggestions.

Worked liked a Charm! By last key, they mean highest or furthest to the right.

It worked! I thought my four-year-old son had broken my CLP 150. All it would do is play the confounded demo! Thank you very much for having this here!

Dear Dennis: It's possible that all you need to do is Initialize (Reset) your unit to restore it to working order. If you don't have an Owner's manual, here's what to do:

1) Turn the Unit OFF, then holding down the last White key, turn the Unit ON. This reset erases all User Settings, Registration Memory, User Songs and Style File; meaning it erasesall your backed up Data.

2) If you want an out-of-the-box ?Factory? Reset.turn the Unit Off, and then holding down the last White Key plus last three Black keys turn the Unit On again; meaning everything, including MIDI info will be erased.

In the hope that either of these suggestions gets the job done, please post a follow-up Forum message so ther members will learn from your experience. Thanks and good luck.
