Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier.

 

As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.

First off, according to the manual, the protect light should be green. That's normal operation. If it is red, that's a problem.

If it does go red, disconnect all of the wiring to the amp except the +12V and ground. Short the remote connection to the +12V to force the amp on. If the protect light still lights red, the issue is inside the amp and will need repair. If the issue goes away, try reconnecting one wire at a time until the protect light goes red again.

SOURCE: Power good no green light no subs

Make sure you got a good ground. do not ground on painted surfaces! If you got power from battery, check the remote wire running to cd player. Hook up remote blue wire with the one for cd player. If you still have a problem and the fuse is good, then the amp is fried

My Power Protector Light wont turn Green


switch off the amp then take off all the wires off including the speaker wire and then reconnect the wires on like before the problem is that the amp is on protection and if that dont work then get it repaired another thing is make sure ur amp fuses havent blown.
