If you have a UPS when it started, remove the mains from the UPS so the PA5X to be disconnected entirely from any external sources (keep only headphones (not connected to other devices like a mixer etc) and the power connection to the UPS) to see if it ll continue reacting like that! |
Yes. Problem go away when my pa5x disconnected entirely from any external sources, only use UPS battery power. This problem also happening in day time, so road lights are not the cause i think. |

So we now know that the issue is not the keyboard but the power supplied to it..
You need an oscilloscope to check what it really is..
It could even be the fridge in your house or a TV.
When it does it , try unplugging each device one by one until it works ok.
Of course that is not a solution when you play in a live show..
For that i would get an antistatic wrist strap to attach it to me and the keyboard chassis ,although it is NOT RECOMENDED AS IT IS NOT SAFE if you don't measure the actual leak voltage!
Hope you find what is the issue!I m here if you need any more help!
