So I just bought an Onkyo TX-SV535 at a flea market for $60. I figured it would be a nice replacement for my rather old Sony receiver that is powering my PC's audio. The unit didn't have its remote or manual but it came in it's original box and whoever had it before looked to take good care of it. No nicks, marks, OSD is perfect, all of the connections look in perfect condition, and face buttons have no wear. I know it's always a gamble buying used but the unit really looks to be in great shape. The problem is when I plug it in and click the Power button it stays in Stand by/Received mode. I pressed every button on its face and nothing, Stand by light is on but it won't power up fully.
Any help would be much appreciated, could it be a blown fuse or I'm I just stupid for even buying the damned thing?
