Default Samson Auro X12D no sound


I have in my bench a Samson Auro X12D for repair. It turns on, the indicator shows audio coming in but after a few minutes playing the "fault" light turns on and no audio comes out.

It is a class D amp using a TDA8954. The power supply is fine. i think the problem is something on the heat detection or on the mute function of the TDA, but it seems ok so far.

I could not find the schematics and the circuit is not the same as Samson Auro d412, it has some similarites but not the same. different design on the amp section.

Anyone experienced with this speaker to give me some light?

have a good day
