martin logan dynamo 700w subwoofer trouble shooting

It does not turn on - no sound, no red light from the status led.

Sometimes - after unplugging, it does turn on, but as soon as I plug in the RCA cables, it turns off again.

Googled it with no results. Any advice appreciated.

Unfortunately the board is busted, and it costs over $220
