Re: sony xm-1002hx

If the fuse blows only after the remote voltage is applied, the output transistors have likely failed. Never use a fuse larger than the one recommended by the manufacturer. It can lead to more extensive damage (including damage to the circuit board) which will make the amp much more expensive to repair.

Overcurrent protector

The woofer or the wiring may be shorted. Remove the speaker wires from the terminals of the amp and power up the amp. If it powers up, check the wiring and the speaker. If it still goes into protect, the amp may be defective. A short in the wiring or speaker can damage a brand new amp.

I have a problem with my amp

Are they all green? If so, that's normal. They go red (or maybe amber?) when the protection circuit detects a problem.
