    Dear Dsom,

This happens when you cross the speaker wires. the amp goes into protection mode. i would check the back for stray strands of wire touching. if thats not it it may be internal.

Your complaint isn't a problem at all. This is a usual characteristic of the relevant amplifier. The protection mode comes on when the main volume/bass/treble or whatever is too loud. Unfotunately, you can not overcome it. But, as they always say: It's a Sony:)

Fans on both indoor and outdoor units are running but compressor wont restart, even after turning power on and turning back on. also, if compressor resets and runs, it'll run for a few minutes then trips...

the compresor have delay protection and this wil not alow compresor to run only after few minits (turn off the unit and disconect from the main power suply, wait 30 minits and after that turnit on) or the refrigerant gas in the plant missing. in this case you must call specializated personel to find the leack and fixit, after that they wil refil whit refrigerant gas (r404, r 134, or what your unit have)

could be thermal overload in motor its a motor protector in the motor when the motor gets hot it cuts power to the motor when motor cools it closes and resets age of drier counts some times you can take drier apart and blow dust out of motor and will fix now if the door is not closing tight vibration can cause door switch to break contact that will do it too most of time motor or relay must be replaced
