Question about Onkyo GX-D90 Main / Stereo Speaker
My onkyo stereo reciever blew a fuse, we replaced it. It made a popping noise, we tried it again, the power does work on it now but it goes back to saying "protect" on the front screen.
An amplifier goes into protect when it detects a load with too low an impedance. If it displays protect with no speakers connected at all, the amplifier is damaged. If not, reconnect speakers one at a time (while the amp is off!) to determine the cause of the fault.
It may be as simple as a single strand of copper wire shorting between the positive and negative terminals of a connection.
