loader might have a faulty belt as if loader is out of alignment unit will come up with mech error

Does anything work? If not the unit is one sick puppy in need of tlc/repair.

It's a Sony problem, I hate to say. My amp does the same thing. Check your speaker wires for a short, if no short, then the auto protection circuit in your Sony is shot - mine was too, and it costs a fortune to fix it - cheaper to buy another one, I hate to say.
