Hi,

I have a Kustom KPM4080 PA that I have been having problems with. It's this one pictured below:



A friend lent it to me so I had something to use for practicing with the boys. However it recently stopped working right, and I'm not the in financial situation (see: college) to be throwing down the cash for a new one. I know it's not a high quality unit, but I'm hoping there's something I can do to fix it. It will power on, but no sound will come through any of the channels. If I unplug it and plug it back in, it will power on and work fine for a few minutes but will then suddenly go mute again. I took it apart and poked around to see if anything was loose or something and hit it with some compressed air, and when I put it back together it was doing fine for about 20 minutes...but then it went quiet again and I had to once again unplug it to get it to make a meager few minutes of sound. I am currently only running one microphone into this. Does anyone have any suggestions about what to do to remedy this problem?
