I have a samsung a300 but I spilt lemonade on it and the inner screen is no longer working the back light comes on and the outer screen is working but there is no writing on inner screen.
I have read posts about water damage but I am not sure if the screen is broken or the PCB needs cleaning.
If the PCB needs cleaning what is the proceedure.

I have priced a screen but it is expensive and I be better off buying a second hand samsung.
