Hi, few months ago I dropped my phone in the lake, momently display is completely correct, but touch does not work. Now my question: is it possible that only LCD is damaged or there is possibility of damaged motherboard, in that case it is easier to buy new one. But if LCD is damaged I can change it by my self. Thanks.

So the j3 lcd digitizer is two separate parts , even though its sold as one piece the digitizer gets attached to the back of the lcd then the lcd connects to the main board. Check to make sure that the digitizer has not come loose .
