I have a 4BSST2 remotely located from my ARC preamplifier. It uses the the external trigger for power up and has been flawless until now. In the last 6 weeks, it would not turn on on about 4 occasions. When I look at the amplifier, there are no LED's lit on the front faceplate, but each time I can see down through the top vents a flashing red LED. -Please note, the flashing LED is not the LED's on the faceplate- If I switch the power switch on the front off and on the flashing red LED continues to flash. If I unplug the amplifier and plug it back in, it immediately turns on, responding to the signal from the preamplifier and the flashing red LED is no longer present. I called Bryston USA technical support and got a strange possible "diagnosis". I was told that maybe the outlet or power cord was interrupting power to the amplifier. This doesn't make sense to me since I can power down and back up, simulating a power interruption and the unit fires right up, no flashing red LED. Has anyone with this amplifier encountered a similar situation? Being an intermittent issue, I don't want to send it in only to have it work okay on the bench. Talking to the tech support in USA didn't instill great confidence, but perhaps he is just a phone guy and not true tech support.
