Water damage

Use a piece of plastic, like a credit or store card, to open up the case.

Lift the cover with a plastic card and carefully pull it off.

Tip: The glue is very strong, so I recommend helping things along with the plastic card.

If you remove the cover slowly and don't stick the plastic card in too far, you might be able to re-use the strip of glue.

Loosen the seven 20mm T5 screws.

Then slide the display upwards.

Now the battery can be disconnected and replaced, if necessary.

This Kindle has water damage which corroded the display cable.

I think changing the display is not possible because it is glued to the mainboard, possibly even soldered. I won't try replacing it because I only need to clean the display connector.
