Hello! So I recently got a HT-S15 from a relative that picked it up on the side of the road. It worked perfectly for about a month. But just recently no sound comes from it at all. I'm using RCA input to the sub and then RCA output to my main amp and speakers. Audio still passes through to my main speakers but nothing plays on the sub. The power LED switches to red on auto when it gets an audio signal so maybe it has gone in to some protection mode? Here is a description of the power LED from the manaul: "POWER LED: Power indicator lamp. Glows green in "AUTO ON" mode if audio signal is present. Glows red in both "OFF" and "AUTO ON "modes if receiving AC power, and audio signal is not present after approximately 20 minutes" In the off position the LED is green for some reason and in "on" it is red. I've checked the fuse and it looks fine. I've also unplugged it for an extended amount of time to try to let it reset but no luck. If anyone has any suggestions that would be greatly appreciated.
