parasound hca-1205a stay in protect

im working on this amp.i disconnected all the amp modules and it still stays in protect? where is the issue? the power/protect board looks fine? is there a way to bypass protect to test it?

After a 5 minute warm up it never happens again. Suggest you locate the protect relay within and give it a light tap to see if it disengages.....
