Hi this is tiny bit liquid damaged near U3900 area.

Replaced R4308 as it was damaged and turns on works fine with out any fault.

But if i try after couple of hours , it wont turn on and need to reset smc or remove battery and connect again to turn on. once it on it works
without failing. Any idea, greatly appriciate.

Thank you,

Regards
Don

Something else affected by liquid for sure.
You may need to reball SMC.

Check reaction on the power on sequence, when the board doesn't want to turn on.
