Hi all I've got an arcam a22 fmj amp that suddenly stopped working. It was playing and cut out. The power led comes on green for approx one second then goes red and blinks. There is nothing on the display. I've tried turning off at power but same thing happens. I've also tried turning off both speakers (using sp1/2 buttons) but same. Any ideas before I take the plunge on taking it back to dealer? It'll be well out of warranty for sure. Thanks a million.
