MtX Thunder 920001 Thermal HELP!!

[rhempz01]

I just finished totally rebuilding this MTX Amplifier. The amplifier ran fine outside of the case and heatsink for testing. As soon as i put the board into casing. Also redid the thermal pads to ceramic?
I could really use some help with this protection curcuit. Nothing is getting hot.

There are multiple transistors with their emitters directly connected (possibly more than what's in the photo). Those are for multiple thermistors. Lift one at a time to see if any one is causing the problem, then trace back to try to find the fault.
