Disassembling the Amazon Kindle EY21 3G

Got a defective Kindle Ey21 3G quite some time ago for a friend. It’s being laying around and collection dust in a hidden corner. Time to put it to good use, by taking it a part for all to see what’s under the hood.

This unit either have a faulty main board or a defective display. It is constantly stuck in the display.

To get to the internals, the first thing is to peel open the front bezel that is glue down with double sided tape.

Once the front bezel is removed, all the screws will exposed.

After removing all the screws, the display can be removed from its housing. Flipping the display over will reveal the main board and battery. The controllers and processors are all hidden under RF shields.

Removing the battery and Wifi/3G modem.

I was quite surprised to find a SIM card in this Kindle.

Removing the bracket that is holding the wireless antennas.

And finally, removing 2 of the flex cable connection on the left and right side of the main board and some screws, the board can be lifted out from the back of the display unit.

Here’s a close up of the back of the main board.

That’s it.
