I’ve had a diagnostic done on an iPad Pro 10.5 (2017) model which won’t power on - it did power on a couple of times then went off after 1-2 minutes but won’t come on at all now. The result of this diagnostic says the company is that it’s not repairable as the issue related to CPU. My question is does this sound like it’s the end of the road for this iPad? Is it worth a second opinion? Can a CPU be replaced?
