Dear Client,

I am sorry to hear about that problem. My name is***** and I am a tech expert with 19 years of experience.

To me, this sounds like a damaged OP-amp, which cannot be really exchanged on your own. I would highly recommend contacting a local Yamaha dealer by going to https://uk.yamaha.com/en/find/dealers/

Thanks for your patience and best regards,
