Identifying which parts of iPad damaged (black screen but mounts ok)?
So my iPad 2 had a run in with a water bottle in my bag a couple of days ago and while I didn't touch it (couldn't think how to turn it off without potentially doing more damage) there was a gut-wrenching moment where the screen flashed on and then off again (without any input).
Two days in the boiler cupboard with a lot of rice and the machine is dry and responds to being plugged in (makes the connection noise and mounts properly) but the display doesn't power up. The home and power buttons work (I can take a screen shot and it makes the camera noise) but I can't work out whether the digitiser works or not (I have tried swiping roughly where I remember the unlock slider to be and it doesn't make the unlock sound).
I'm trying to decide whether it's worth attempting a repair but am trying to work out what bits I'm likely to need to replace before I start burning cash on a potentially lost cause.
Does a blank screen and a suspicion of no touch input suggest an LCD + digitiser replacement, a logic-board replacement, both, or is it really impossible to tell? Is it possible to have partially borked the logic board but it still be able to boot, backup, restore etc. (all of these things still work).
If anyone has any ideas for other diagnostic tests I might be able to perform to localise the problem that would be great!
Is this a good question?
