ZRX2416.1D

This amp came in with a blown PS.After getting the supply to work i realize the amp is taking to long to get out of protect sometimes, especially the first power up after i let it seat for a while.It acted that way even when i had no PS FET install.Any suggestions?

For pins 1 and 7 of the 8-pin comparator on the driver board, which pin 1 or 7 is near 12v when the amp is in protect?

They should both be near 0v.

Pin 1 remain at 6.84v when amp is in protect.

The attached diagram should be close. The section of the comparator that's going high is used for over-voltage, over-current and DC offset. You need to determine which is causing the problem.
