So the blue channel on my ocean revive T247 LED fixture when out this past week. After trouble shooting and looking at the divers, (swap the 2 around) the timer and switch (seemed to be working well as I alternated the wiring harness between the 2) swapping the fans around (one was working, one was not, but that didn't interfere with the LEDS, though the bad fan could have caused overheating), I concluded that the LED plate was the problem. Took it out and touched each diode with my multimeter and found that one diode didn't light up. I grabbed a copper wire and touched it to the bad diode's contact points and the entire panel lit up. So it was an actually an easy fix, I replaced the diode using solder and iron.
Moral of the story, LED panels are set up like cheap Christmas lights in serial connection. One goes out, the entire array goes.
