My Lyric is performing intermittently. Sometimes it works (and sounds great) then often it will just cut out (no sound). It worked great the first couple of months but is becoming progressively worse and I never know when it will work.

I have pulled the system out, ensured a good battery, wiggled a little bit to check for loose wires but cannot get it to work now.

I know it is with the system because I have tried plugging directly into a small amp with a known good cable and amp.

Any suggestions? I had hoped exchanging would be a possibility but am about a month past Musician's Friend's return date, plus I did not realize that installing it myself would void the manufacturer warranty. It was very easy to install.

Thanks in advance for any help,
Brad
