help with sick Digitech pds2700



Hello looping friends.  I have a tale of woe that I hope the more
technologically sophisticated among you might be able to help me cope
with.  I have a PDS 2700 which I adore and which is now (temporarily I
hope) silenced by an unknown malady.

It started with loud hum that would suddenly kick in in the middle of my
playing for no apparent reason.  It was loud enough to overpower the
guitar signal.  To get rid of it, I would unplug and replug the adapter
(9 volt, not the recommended 10 volt).  Sometimes it took two or three
such hard resets to get rid of the noise.  Then one day Mr. Green just
stopped putting out any signal at all.  The LEDs still light up as if
everything is fine, but no signal goes through to the amp, not even the
accursed hum.

I opened it up and don't see any loose connections, just a lot of
intimidating integrated circuitry.  One curious item -- the stereo
output appears to have only one lead.

In any event, I am hoping against hope that someone may have suggestions
for repair/troubleshooting.  Could the 9v adapter have caused the
problem?  The unit currently doesn't work with batteries any better than
with an adapter.

Thanks in advance for your looper compassion.
