This morning, I took out my pair of AR570 Powered Partners from a box after probably about 10 years of non-use. It worked for about 10 minutes then one of them lost power and can not be turned on again. Flipping the power switch have no response what so ever. Does anyone have any experience with this problem on this speaker? Thank you in advance for any help.
I'm sorry I no longer have mine. Maybe someone else can chime in. According to the photos I have there were 8 hex-socket head machine screws on the back and I'm pretty sure all 8 have to be removed, but maybe not. The 4 in the middle are for attaching the "clamp" so the speakers can be mounted on a pole. What about the knobs on front? Do they pull off? Maybe search "powered partners" in the AR forum, find members who have worked on them and send PMs. Here is a manual for the similar Advent 570 h
