Hi Rojaslaz,

Welcome to the forum!

First, I am going to point you to the Power Station troubleshooting section of the forum:

Power Station: Troubleshooting Guide

WON’T TURN ON Make sure AC cord is securely connected at both ends. Verify the power source with something you know works. Check the mains fuse, and replace if necessary. If it blows again, refer to qualified service personnel. NO SOUND Check input cable. Check volume controls. Make sure the amplifier volume and/or gain controls are turned up. Unplug the FX loop, check for sound. Connect a jumper cable from FX send directly to FX return; check for sound. Connect a jumper cable from Line Out d…

Second, I’ll explain the whole myth about “I’m in the same outlet as the amplifier so there is no ground loop”. That’s absolutely not a guarantee there won’t be a ground loop. Ground loops can occur for many reasons. Also, I’ve seen some pretty crazy wiring when it comes to home circuits.

Third, why have the amplifier off when you are testing?

Fourth, what cables are you using coming from and going to the amplifier? Those look like standard audio cables. Also, make sure those right angle plugs aren’t touching each other. That’s another ground loop source that can cause issues.

I want to get you back up and running as quickly as possible. Let’s try to get this solved together. Let me know about the questions above and let’s get you playing music again.

Thank You,

Terry
