Obviously it is affected by moisture. You can remove the damaged original parts first, then power on and test whether they can work.

I don't have the tools for such precise work at home. Right now, I can power the board with USB-C, solar panel connector does no work, and I can power through internal battery.
But I found that when I have a USB-C solar panel connected and internal battery, when the solar panel is not able to produce enough current, the device shuts down instead of switching to the battery.
I do not have this behaviour with the second board.
I have ordered a spray for electronic boards...
But what I don't understand is why these boards come without any varnish, silicon or resin to protect the components from humidity / moisture ?
Also, is there a solution I could do to cleanup without having to remove the components ?
How I could check if some are damaged ?
Damaged capacitors visible to the human eye can be removed first and then replaced according to the parameters provided below
@lewisxhe : do you know what kind of product I could use to cleanup and remove this blue-green mixture ? isopropyl alcohol ?
I was able to clean the board with some isopropyl alcohol and I can power it through USB-C and battery, so even if some PMU settings have been affected it is stil usable for some other projects.
This issue is stale because it has been open for 30 days with no activity.
This issue was closed because it has been inactive for 14 days since being marked as stale.
Hello,
I am testing the lilygo board outside since a few days. There is a lot of humidity outside, the lilygo is in a waterproof box (but the box has a hole for the wires on the side, so the air can enter but not the rain).
I am wondering what's this on the board ? it was not there before. It feels like the humidity stats damaging the board ?
The connected usb-c device is this solar panel : https://fr.aliexpress.com/item/1005005509831452.html
