Problem solved. For all those who have this problem and have checked speaker cables are not shorted etc first - here is the solution. Turn amp upside down and remove the 6" (approx) square metal plate that is screwed on to the base. With the front of the unit facing you, the circuit board board on the left (Input board) is where you'll find two ICs labelled IC501 and IC701. Look carefully at the solder joints and you will hopefully see they are darker and grottier than most of the other shinier solder joints elsewhere on the board. Re-solder all the legs of each IC - 15 pins on each. You may need to remove the old solder first. Check for other near-by components that also have bad looking solder joints and re-solder those too. The two ICs are part of the protection circuitry and they appear to get pretty hot causing part-melted and part to completely broken solder joints. People who have the symptom of permanently in Protection mode should also be able to solve their issue with this solution. Hope this helps somebody out there. Cheers Dave
