Water damaged phone, boots up but screen not working
The phone got drowned ca. 4 months ago. It didn't spend much time in the water, it was quickly pulled out.
When I charge it up and try to start it, it vibrates and I see the LED diode flickering. It seems like a screen problem to me.
Today, I opened it, and I barely saw any damage at first. I first replaced the old screen with a new one. Doesn't work. I then noticed that a few pins at the edge of the screen connector on the logic board are black. I think this might be the problem.
Not really sure what it is, I think those pins got shorted from the water. I have no idea how to clean it.
So far I tried scratching it off with 99% isopropylalcohol and a knife, but it just doesn't come off.
I have submerged it into iso and it's sitting there right now, however, I doubt it's gonna help.
from the sounds of it you might wanna check caps and resistors also.
can you see the pin in the connector? you may need to solder on a new connector at this point if you cant clean the pins to make a good contact.
