My marantzsr5200 powered off and won't turn back on. What do I do? There is a light flashing red. this is not an overheating problem or fuse problem. It happened when I was trying to program the multi-zone feature.?
Try to reset the memory circuits, the info on them may be corrupted, try this: 1 disconnect the plug from the AC line supply 2 wait 10 minutes then, reconnect the plug to the AC outlet 3 try to operate the equipment. now.. if above does not work you
