IS water damage invisible on logic board?
Still trying to fix this sucker.
Dropped in toilet three days ago.
Let airdry for 6 hours.
Plugged in to PC (I know, dumb). It restored.
Let air dry 2.75 days.
Removed glass. THe LCD has a black spot the size of a dime and one streak.
I am looking at the logic board to see if it has water damage.
I don't see any signs of corrosion. Can it be invisible?
the black spot on the display is normal for a broken one - but for now - wait until you buy a new one!
fluid damage ins't invisible - but sometimes it's tiny - the parts in the ipod touch are sometimes pretty small and you need a magnifier to see if something is shorted.
don't forget to look under the logic board - most people are only looking on the top side of the board!
get some isopropyl alcohol mith more than 90% and a soft paintbrush, use it to clean the board and the connectors - be careful - those parts are very fragile!
let it dry (1 day should be enough) - don't use a hair dryer for that!
reassemble it and try it again.
