Ty, the AM5 III is powered on/off from the head unit which is probably a Lifestyle 5 or some such. In order to service it you'll need the cable that goes between the AM5 and the LS5, the LS5 and maybe the remote control. Also you'll find it impossible to purchase parts from Bose unless you are an ASC, they have gotten to the point where even the ASC's are not allowed to repair some products even when out of warranty and they won't sell us parts for products they have specified as factory serviceable only. I had to return two units to customers last week for just that reason. The AM5 series III is field repairable but the AM5 series II is not. Additionally if you are dealing with a lightning damage situation you may have to replace both boards to fix it or plan on retiring before you get it fixed. Should you decide to accept this mission............I can feed you information. This message will self destruct it 5 minutes! ******************************************************************************************************************* Since 1972 Jim Myers Telrad Electronics Fort Wayne, Indiana Ty wrote: > Customer wants this thing fixed. > Problem is that I have no idea what is what on this thing! > Has a 5pin Din input.
