E2 display in Behringer X Vamp lx1-x


Hello everybody, nice to start this topic, it's about a Behringer X V-amp lx1-x, well i have one and it isn't working anymore, the only thing i got now is a "E2" message displayed, but nothing happened when i restarted or shut off.

I'm asking what is this about, i red the manualsbutboting about troubleshooting, is there anyone that can help me to solve this?

Thanks to you all, greetings from Peru
