Hi everyone I have a 2550 build that was finished and everything was working all of the sudden it cut out a couple times then I lost the lead channel. Relay test good, voltage to the Relay is good and drops when toggle switch engaged. I double checked my wiring and its good. Like I said it worked before. PS Board getting power fomrthe heaters and giving power to the Relay board. The channel indicator comes on like its switching channels but no OD and the lead master volume doesn't work. Any help would be greatly appreciated. Thanks
