Begin with disconnecting ALL the speaker wires from the back of the receiver, then power up the receiver to see if it continues to go into "protect mode", if it DOESN'T, then you know that one or more of the speakers or speaker wires has a electrical short in it / them!
Closely inspect all the speaker wires to see if there is any bad, worn, bare spots or anything that looks not right, if so replace ALL speaker wires!!! If all wiring looks good, then you may have a "BLOWN" speaker which is actually a dead electrical short, and the the speaker(s) will have to be replaced!
If all speakers are in good condition, then your receiver or one or more of the components that you have connected to it has an internal short and will have to be repaired or replaced.
GOOD LUCK !

Lamp indicator flashes red 3 times every 5 secs.


Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

This is a qsc plx 3002 power amp. when i plug it in the green light shows it want to power up but does not. instead it makes clicking sounds like it does when it goes into protection mode.within 10 sec....


You are correct, it is in protect mode, usually caused by an overload.
You need a QSC Service department for repair.

Sony STR-V444 suffer, like all amplifiers, from dry joints caused by vibration. Resoldering the output section on both machines may indeed repair them.

It's very likely that the output transistors have failed in the amp. They will need to be replaced.
