iPad keep restarting on Apple logo - some pink screen

Hello,

I have an old iPad that I’d like to try fixing myself as a personal project.

The problem is that it’s stuck in a restart loop. I see the Apple logo, then it seems like there’s some kind of short inside, and it restarts again. Sometimes it shows a pink screen, and other times it manages to boot into iOS, but after a few minutes it shuts down and goes back into the loop.

The battery is fully charged, and I also tried doing a factory restore, but I can’t complete it because the iPad won’t enter restore mode properly—iTunes throws an error.

My questions:

• What could be the hardware issue?
• Where can I buy the spare parts?

Thanks!
