System turns on but only hear feedback fomr speakser no sound

turn down the volume.

MAke sure your channel selection is correct.

check your hearing at the medical center

Understand that in a feedback system if the gain exceeds plus one, it will oscillate. This sustainer kit PROBABLY pushes the gain up close to this feedback point and that is the way it works when set correctely. This is called regeneration. This is technical stuff...

The pickup heights are likely the main control of this feedback gain, so raising the strings up relative would be in the right direction.

ALSO IF your guitar can "hear" your amp, then you can have feedback due to the sound vibrating the strings. Try turning down the treble on the amp and see if that might help.

Some electronics when run with dying batteries becomes unstable.

These are just suggestions based on my engineering experience. I wish I was there to run some tests as that is the way to troubleshoot.

check speaker connections.sounds like the system is trying to stop some thing more serious happening by shutting itself down.a pain yes but saves blowing something up.if no luck,then definately send in for repair

disconnect the monitor from the back of the system and see if u see the colour scheme or anything if u do see something that means monitor fine ... problem with system

Is it through an IM program? If so I had a simular problem and I open the sound settings and made sure non of them were muted and it worked fine after that.

Having the same problem, Please help.

use the speakers it came with it works fine for me i have mine hooked up to a 300w inverter anything less i dont get the best sound you cant turn the volume up too loud on the reciever it will draw too much power and shut it off or blow the fuse in you car unless the inverter you are using has an external fuse on it my inverter warns me that i am drawing to much power so when i hear the beep i turn it down a notch and works fine but ya try using the speakers th system came with

Plug in your headphone, if you hear music then it could be the speaker's fuse blown up, or the speaker's circuit breaker shut down. If nothing sound then possibly the strong static has burned down the audio/receiver's circuitry section.
