Follow the path of voltage from the remote terminal to the PWM control IC. Look for shorted or leaking diodes or transistors connected to that path. Look for small wire fragments that may be shorting the power terminal to the remote terminal of the amp.

What are the numbers on the PWM IC? XX494, xx594, SG3524, SG3525?
