Chosen Solution

I dropped my phone in water and the back glass was broken. I soaked in rice and blow dried it. about 12 hours later i tried cutting on and the apple logo appeared clear and like usual. A few seconds after the apple logo popped up it went blank and never would cut back on. I just replaced the battery and cleaned all connectors with alcohol. Still won’t cut on. Any ideas or remedies at this point?

The logic board probably wasn’t completely dry when you powered it on. It was still wet, and now likely damaged.
