Macbook Air water damage?

[kwatramoe]

I water damaged my macbook air 2012 a1466 about a year ago nothing worked when it got water damaged. I placed it in rice and replaced the battery, and my laptop started working perfectly no glitches. But now after a year I am having trouble with this laptop sometimes when I plug it in to the power source the screen goes blank and there is no light on the macbook charger but when I pull out the charger the laptop works fine. Sometimes when I tap the laptop from the back around the I/O board area the charger starts charging and everything works fine.But after my laptop is physically moved around a little the problem will occur again and the laptop will screen will go blank and the laptop itself will be unresponsive when I plug in the charger?
Everything in the laptop works perfectly except that issue of the battery not charging sometime.

Tapping the laptop from the back does not always work so I open the laptop and just disconnect the I/O flex wire and after a while it will sometimes work but when I move it again it will stop.
Also the laptop has a 3rd party battery and a 3rd party charger

What is wrong with my laptop?
what part could it be?
I think its the I/O flex cable? or the entire I/O board ?

PLEASE HELP

Sounds like faulty I/O cables you should try running the apple hardware test (power off macbook) ‘Press the power button then immediately hold down the “D” key until you see a spinning globe. Make sure the power cable is plugged in while running the test.
