Phone Screen not working (no touch)
A while back, I dropped my phone in water and immediately disassembled it to dry it off. The symptoms were a screen that either worked perfectly after reboot and then turned black every time the screen was turned on, or a perfectly functional device except that the digitizer did not work. So, after reading some "advice", I soaked my screen in 91% alcohol, leaving permanent marks. Then, I soaked the logic board in alcohol with a vibration assist from a washing machine. The logic board seemed to be fixed, and being a perfectionist, I tried to go a step further by using a food dehydrator to dry the alcohol marks out of the screen. However, after a while of drying (of screen only, vacuum sealed into a container with silica gel and dessicants), the screen digitizer does not work anymore.
My question is this: is the problem with the screen or the logic board? I noticed that some antenna contacts were slightly bent out of shape, but I am not sure what happened to the rest of the board. There doesn't seem to be corrosion. Keep in mind that after the laundry machine vibration, I took the board out of alcohol, but after I discovered the screen issues, I put it in for around 24 hours.
If needed, I can send photos.
