OurConcertone Zx600 appears to be playing but no sound from the speakers. Have tried everything including resetting. It will not reset holding down the function as the Manuel suggests. Anyone know how I can reset it?
Pull the main power plug off of the back of it for a few minutes. If this does not work it will also give you the chance to see if it is putting voltage out on the speaker leads. If not it may go in the pile of concertone amp failures.
Took it out and couldn't get the power cord off. The screws have been stripped. Will take it to Car Toys and see if they can come up with a replacement.
