iPhone 5s will not turn on or charge
This iPhone was purchased and activated about 2 years ago and has had a screen replacement several months back. Two days ago, the device was left in a vehicle overnight. The device had been exposed to cold (<32 Fahrenheit) , but not moisture. After retrieving the phone, the battery had been depleted. While recharging the device, a series of colored lines flashed across the display before it went dark. After a few hours, there was still no change. I opened the phone to examine any possible damage, and saw none. After assuming it might have been battery failure, I replaced the battery with a brand new one. There is still no change. The battery warms slightly as if charging, but the screen is completely dark with no charging icon even after considerable charging time. Hopefully it is not Logic board damage. Any help would be appreciated.
Is this a good question?
