So here's what a water damaged radion board looks like. On the surface, not a big deal, other than some pealed paint on the RF module and the blown fuse:
The fun begins when we flip the board look closer at the disaster. Lot's of oxidation all over the place:
Especially in this area:
Oh yeah, baby. This is not looking good at all:
A part of the chip burned off, taking some pins with it and creating a crater on the board:
The main controller has a hole in it caused by burning from the inside:
And some other miscellaneous damage to resisters and whatnot:
Why so much damage you ask, especially considering that there is a blown fuse?
Ah, that's more than likely because the fuse is rated to handle a large load of ~150w required by all the LEDs. It's not there to protect your little main board. So when the salt water hit that board, all of that 150w of power, enough to illuminate a house, rushed to those small components you see butchered.
For those curious as to the outcome of this case, given the amount of damage, the main board is not in a condition where it can be repaired and will have to be replaced. Good luck trying to get ecotech to sell just the board.
