iPhone recognized in iTunes, but no other signs of life?
I bought a broken iPhone 6 on eBay for the sole purpose of using the logic board to fix my iCloud locked iPhone 6. The phone was extremely damaged, the top 10% or so almost looked shredded. The logic board looked intact, however it slightly bends down on the border of the display connectors and the motherboard, about 20 degrees or so. I installed the logic board, charged it for a while, and it was recognized in iTunes, but I could make out nothing. The phone made no vibrations or noises, and changing the ringer has no effect. The logic board had water damage, the SIM tray indicator was tinged red, so nothing too severe. Is there something else besides the backlight that could be faulty, to cause the phone to be unable to make sound or vibrations?
Thank you in advance for any assistance.
Is this a good question?
