Duet2 Wifi need to be repaired, not under warranty

pipersw

Hi,
I do watercooling on the Duet, and some liquid cooling (said nor conductive by the seller, but conductive in real) have flow down the area of X Y drivers, bed mosfet, wifi module etc... and now the wifi module don't start, it start only in USB if I enable it.
3,3V and 5V led are on, debug led light on then off, endstop leds worked if I move the axes by hand, sd card is not detected (change by another with same results, and webpage is not available.

How to proceed for return the board (buyed online on Duet3D) for repairing ? How estimate the cost of repair ?

I will take picture as soosn as possible of the board.

I am in France.

start by posting a picture of it?

the vin led does not come on? but you can connect to the board and use wifi when powered by usb?

All the LEDs are ok, without the blue LED of wifi in standalone.
5V is external, and 24V VIN is commanded by PS_ON.
with 24V VIN off :

with 24V VIN forced to on, VIN LED bright low.

With USB, I could communicate by yat, M122 respond by exemple.

if you're lucky all you need is a new sd card socket. the leds on the ends stops are on, are they working if you look at the machine properties or use M119?

You'd probably need to strip the board down and use some more light to get a good picture to evaluate

Are you watercooling the drivers on the Duet?

@warpster yes, drivers and processor.

Somebody know the reference of the microSD card socket ?
