Promix 1212E Mixer

I have a Promix 1212E mixer, and I need your help.
The same as I turn on the LEDs of the Peak information are active, thus not allowing any audio signal at the output
I would like help because I do not have a technical plan and I have no idea what component will be broken
Thank you so much
