iPhone 5s power button stuck down?
My iPhone 5s won't start up. Screen is blank and battery (by now) is discharged. Pressing the power button doesn't make anything happen.
The power button seems stuck down. No click or movement felt when pressing it.
Connecting the lightning power cord gives an immediate Apple logo for ~20 seconds, sometimes followed by a brief full-screen red flash, then the screen goes dark for a few seconds before the Apple logo reappears. This cycle continues indefinitely.
Thoughts? Many thanks.
Update: The red-screen doesn't always happen.
