Korg Pa4x Output Problem

[MikeProd]

Hello to all! My problem is that my left output drops down the volume almost to 0. I did reset factory and hard reset but still the same thing!
This not happening when i turn on the keyboard! Only after 10 minutes or so after i turn it on.
Any idea what must be this bug?

Hi,

Sounds like a hardware issue on your L channel signal. Try changing your cables and if it still continues, you can contact your local repair service.

I do not think the problem are the cables! This is happening when i put headphones too. Anyway thanks for the reply.
