Alpine MRP-F200
Ok i have this amp in for repair also. Channel 2 is dead. I hooked the scope up and see that i have the signal on both positive and negative terminals for that channel.

What cause's this again?

The connection to the non-bridging terminal is open/broken.

I dont see any boken traces on the board at all. So since the right channel is number 2 do i trace the positive terminal ?? Since the left positive and right negative are for bridging

Yes. You can move the speaker wire from the non-bridging terminal of the dead channel to the non-bridging terminal for the other channel to see if the channel will produce audio.
