Korg N364 volume is blairing loud

[Frozen Smoke]

Hello all,

Started playing the other day and I’ve encountered an issue. Hitting the keys with with any more pressure than normal, maybe slightly triggering the velocity sensor and the sound is so unbelievely loud it could almost blow speakers or headphones. I’ve read a couple of things saying it might be the velocity sensor on certain keys, however in my case, is doesn’t matter which key I press.

Also, there is a weird hum if you apply hand pressure to the top of the keyboard where the n364 logo is. It sounds like a mic or something creating feedback. I thinking this is somehow related.

Any help would be apprieciated

Thanks
