Display works only after letting the battery go flat :-/

I got given an IPAD Pro 10.5 inch from my Aunt which failed after only 13 months of use during Covid and Curry's wouldn't replace it, seemed a bit unfair.

When the ipad battery is left to go flat, the screen will come on for a few seconds and show charging and will actually show the screen for a few seconds once charged. After that the screen goes black. I have plugged in the Apple HDMI and connected to a screen, the IPAD is working without issue and I am able to run updates etc.

The IPAD has not been opened, no visible marks on the screen, a very small mark on one of the corners.

Seems strange the screen will come on fully but only for a few seconds, I would have thought if the screen was faulty it wouldn't come on at all. Also seems strange it relates to only working once the battery is fully flat.

Any ideas.. most welcome, would be good to be able to give this device a new lease of life for the kids.

Hello dave,

It looks like a hang due to an incompatible app. The manufacturer has provided an option to restore factory settings for this solution. The key to everything in your case is the tablet working despite the screen issues. Naturally, the next step will be the screen, but more on that later. Charge the tablet to min.50% and enter the tablet into recovery mode. If it's a software problem, it will be fixed, if not, it will be a trip to a good repair shop.

In a good repair shop, the screen and the operation of the electronics of the mainboard will be diagnosed. Perhaps it has to do with the battery, I don't know without taking measurements, but it seems unlikely to me. The most likely scenario seems to me to be signal processing through the screen. This will require detailed diagnostics and at least a few hours of work.

Good luck.
