Hello, I have a Yamaha P95 keyboard, I have the following problem:
After turning it on, the keys work but the pedal and additional functions (metronome, rec, grand piano, jazz organ etc.) do not activate.
Can someone please help me? Thank you very much.

Welcome to AAC!

The first step is to find the circuit schematics.
The next step is to take and post photographs of the piano control buttons.
Then you will have to open the piano and take sharp well focused photos of the boards inside.

I am sending what you requested. I have the circuit diagrams, I checked the voltages on IC401 and IC402 (AM diagram) and they are good +5 v, I went to the voltage regulators of the DM board and checked the voltages on IC501(+3.3) and on IC502 (2.5V) and they are good.............What else do I have to do..............Thanks for the reply
