JL Audio 500/1 V1 always on

I have a Jl Audio 500/1 V1 that play fine but is always on, even with no remote turn on input signal. It turn on just with the +12v and gnd wires.

Please help me to find the faulty part. Thanks.

I would be checking the pwm chip and the comparator if used, I am not familiar with these.

I had a Rockford amp do this one time and it was a defective LM339D comparator.
