Phoenix Gold Phorum

So, im playing with my new power supply, zx450 turns on, normal sequence, but no output-I checked the output transistors, there perfect, so i pull the cover, and check both ribbon connectors from main boaard to xover board, they are connected, pull out my DMM, i check(in diode mode) the external , or aux output rca solder connections, and get readings, i check the front /rear input rcas(were soldered to the board), and no readings, is it possible for the actual rca inputs to just go bad???, if this is the case, then obviously desolder them, and put new ones in, does anybody have any other ideas, or area to steer me to b4 i go down the road of replaing the front/rear rca inputs? and thanx in advance-

also, i did take volatge readings at the input power/ground/remote, with the power supply on, and was reading 13.7 volts-
