WS420 LEDs not on
So last time I was home we went out on the water and all but 2 of the LED backlit rings on my WS420 decided to not light up. Anyone else have this problem??? The only two that work are the volume knob and PA knob.

That is odd for several reasons...those LEDs last forever in our experience, to have multiples out simultaneously is even more rare and all those LEDs are on the same circuit.
Pop the top and look for signs of corrosion like a white powdery residue. The circuit board is conformal coated but the LEDs are stood off the circuit board.
The WS420 uses all sealed pots at the front of the EQ which make them highly corrosive resistant so it is possible that the issue only arose with the LEDs.
If you have evidence of corrosion then use a very soft bristle toothbrush and spray can tuner wash to clean the board.
