any clues why the protect led is on

1. presence of DC referent to Ground/chassis before output relay?
2. unbalance in output power rails
3. overtemperature sensors on heatsinks...
4. the difficult one: overload due to short on output
5. failure of "delay on" circuit
Just suggestions of usual protections which cause muting to be active.
