Liquid damage so screen doesn't work but everything else seems to work

So, I spilled coffee all over my iPad. After drying it out I tested it and it actually restarted to the home screen but the touch screen part of the display didn't work. I was able to see that bluetooth and wifi worked and so it seemed the damage was centered on the display. After shutting it down and restarting over the next day or two the device began an endless loop of restarting. That's when I decided to disassemble it. Currently I have the display off the device and deciding on my next move. I'd like to repair it but has questions.

How best do I test the device aside from the display to determine they are sound?

Does the restarting behavior I described above make this issue more severe?

Is the corrosion taking its toll on this and no worth to repair?

I'd appreciate any thoughts. Thanks,

Update (03/22/23)

Took the device apart. Would be curious on your take on how bad or not so bad these look.

I'm planning on cleaning these up and giving them a go. Thanks.

It sounds like coffee got inside your iPad. If you can shut your iPad off as the liquid could short the logic board and is most likely causing the restarting. You are also going to have to disassemble your iPad and clean the Logic Board and all connections with a soft brush and a high-grade (90%+) isopropyl alcohol, (YES, you can submerge the board in isopropyl alcohol).

Depending on how long after your device was water damaged, then there shouldn't be too much corrosion. Or at the very least none that can't be fixed with Alcohol. And the best way to test would just to try and use the device and test what does/doesn't work. I also recommend this article for more information on liquid damage.

Hopefully, this helps.
