Ipad bootlooping/not powering on/ powering off after minutes of activity
I have an iPad Air 5th gen with iPad OS 18.3 . Last week it started boot looping for an hour before stopping. Two days ago, it started boot looping again for several hours before eventually stopping and booting normally but then shutting off as it was then last evening. Yesterday afternoon, it was working normally before it started bootlooping but for much longer and when it stopped bootlooping, it would either:
a) Remained powered off despite repeated attempts to power it on and despite the battery being charged (no sign of battery damage or severe degradation)
b) Power on, functions fine for a few minutes or so before powering off and then either bootlooping again or remaining switched off until it powers on again and switches off subsequently, repeating the cycle .
Now, try as I might, screen won't even light on . In the beginning when it was bootlooping, I thought this was a software issue that could be overcome with a refresh/restart or an update or me installing the firmware via iTunes. Now, with it not even powering on, I'm starting to think there must be a hardware aspect to this, either something inside has come undone or something is damaged. I'm planning on taking it to my authorised apple reseller in my region soon but I thought I might find some answers or options here that I wouldn't have considered.
Thanks in advance
