phone was wet, powered up before drying (no, not by me) screen flashed some colors and patterns. powered off and on a few times with same results, then all black screen. phone charges and makes unlock sound when swiped, but has all black display.
Is there a way to tell if it is the screen or the motherboard? I don't really want to try both, that would put me in new phone cost.
Thanks.
Is this a good question?

There's no real way to tell until you clean the board with ISO alcohol and try again if screen still black then you will need to try a screen

Best of luck to you. I got my S3 wet the other day in saltwater; I didn't power it off right away either and it went through various flashing, etc. But I did open it up after that and have been drying it for days. I used rice first, which I've learned can help or not; it seemed to help mine some as I've regained some functions. I have also left it open with battery removed to air out as another site indicated, and I used my dehumidifier also.
It's now showing that all appears to be working, and I receive calls/sounds/notifications.
It won't recognize my input on the screen. Should I clean the motherboard, and where is that located? Thanks!
