So I accidentally put an open water bottle in my bag while my tablet was in there, LCD was unfortunately flooded, but I ordered a replacement screen and it arrived today. Though opening up the tablet I found water droplets throughout, so I removed every part meticulously to put in rice or something and noted any current corrosion I had to remove with a q tip.

My question is this. As soon as I opened it up I noticed the water very quickly evaporating. I actually can't see any more now. Anyone who does mobile device repairs, what do you think? Could I skip the deep-dry? I looked at all the components and none of them have any parts that could have trapped water that I missed and I don't really look forward to cleaning the entire thing of starch ( though I do just have silica beads but let's stay on topic)

Am I right to feel confident about the dryness of the components? Let me know!

You ordered a replacement screen and wait for it to arrive before even opening the device? Why?

Removing corrosion means it will be harder to see where the damage is.

Next time:

  1. Open as soon as ASAP possible!
  2. Disconnect battery.
  3. Let it dry. No rice or dog shit or whatever. Proper desiccant or nothing.
  4. Reconnect battery and test.
  5. Win or start debugging.
  6. Fix it
  7. Remove corrosion when everything works only now - unless you expect it to cause the issue, then at least document it before cleaning.

Making a few assumptions here,

  1. I hadn't thought about it, but the device worked and the screen clearly had liquid trapped between the layers. So once I saw that I turned it off, and ordered a new screen, because believe it or not, desiccant doesn't do jack for a waterlogged LCD.

  2. I said "noted" corrosion, not that I went ahead and removed it

So the Qtip part did not happen? Ok.

No that's gonna be after drying, I also have this really fancy HD microscope I use for solder but I'll be checking out each component I can looking for damages
