Can salt break a LED lamp circuits/board? (weird problem) : led

Hello everyone I have a really weird situation. I had two Yongnuo YN-600 Air LED photo/video lights. On these lamps it says “DC, max input 8V, 5A”.

I was sold AC adapters to those lamps 12V 5A. They were working properly in the beginning. Then I started traveling with those and at one point lots of normal kitchen salt spilled in my travel bag (I didn’t notice). Some of this salt got into the boards of the lamps – I thought it does not matter so I used the lamps normally.

Suddenly one time one lamp after turning on with the AC adapter started blinking and then something got burned on the board – lamp completely dead. The 2nd lamp worked well.

Then 2 weeks later the same started happening to the 2nd lamp (it still had some salt inside the case). Now it blinks every time I turn it on but I immediately switch it off because I’m afraid of breaking it completely. So now I am not sure – is all of this a salt fault? Or maybe one of my AC adapters is faulty and broke both lights? Any suggestions about how can I check which AC adapter may be faulty? I want to buy new lights but if one of them is bad then I don’t want to destroy new lights…

If anyone can comment or help me with this I would be really grateful!
