Allo Katana suddenly no more sound & getting hot.

[Jan62]

Dear support,

My Katana is producing no sound anymore,

All indicator lights act as if everything is OK.
There were no changes made to the setup.
Volumio was updated to the latest version a couple of weeks ago.
I use a power setup with 3 psu,s.

The on board +/-15v generator switch is ON.
The blue B1715 capacitor on top of the microcontroller is warm.
The PCB underneath the printed word "Controller" is getting real hot.
The power measurement are off compared to https://github.com/sparkysbc/sparky_linux_images/blob/master/katana-Controller-V measure-points.pdf

 

Any idea how to fix this?

Details, pictures, etc on request

Dear Ahnam,
Contact Allo support, they will instruct you to perform a number of measurements to identify if components are broken. [ https://github.com/sparkysbc/sparky_linux_images/blob/master/katana-Controller-V measure-points.pdf]. You also have to make some pictures of the setup and individual cards.
Most likely they will inform you what to do next.
In my case I got great support and service.
So keep the spirits up, fix this issue & enjoy the music !
