no sound from speakers....

Archived from groups: rec.audio.tech (More info?)

I have audio system setup installed by prof... 4-5 years working great
with no problems Then I turn on the receiver last night and no sound.
I "fixed" the problem that night. (wire connection ) I stripped the
wire for new connections and everything was working dvd, radio, vcr
etc.... Now 24 hours later the same problem no sound from speakers.
this time I reconnected the wires. It works for the moment.
Some suggestions would be great,
is the wire? change it? guage etc.
Thanks

A novice in over my head.

Also consider that speaker wires run through the walls could have been
damaged by some event like hanging a picture or shelf....
