Introduction

The Kindle Fire HDX 7" is reasonably modular in design and most components can be accessed and replaced. Opening the case requires patience and some good spudgers. Disassembly is hindered by the liberal use of double sided tape and some odd-sized screws.

Replacement of the screen, probably the most vulnerable component, is not covered and is somewhat harder.

  • Counting the six T3 torx screws from the left, remove numbers 1, 3, 4 and 6. Leave 2 and 5 (the outer pair of the middle four). Keep them safe.

Precisely you need also Torx T4!

These photos show the device with nothing but the screen removed and are for information only - you will not see this view.

  • Working around the edge of the screen with a spudger, release the tabs securing the back. You may find it best to start with the sides, working down from the top. Then release two tabs either side of the camera before tackling the bottom.

  • Once all the clips are free the back is still secured to the back of the battery with double sided tape. release this slowly and gently. Do not apply and sharp or hard instruments to the battery in order to hasten the release.

  • Carefuly ifting the back, you will find that it's still attached to the motherboard by a ribbon. Remove the tape which secures the connector, the lift the connector off the motherboard socket.

  • If you need to replace these components, remove the power button and micro-USB port cables using a spudger. If not, skip this step.

  • If you need to replace the speakers, remove the two remaining screws from Step 2, then lift them out. Otherwise, skip this step.

There seems to be a huge gap between step 6 and step 7. The illustration changes unrecognizably. How do we get to the view in step 7?

  • Pull off the two antenna cables from the motherboard and the tape which holds them to the motherboard.

  • Remove 9 screws securing the mother board.

    • Note that these screws seem to be something between T5 and T6 and may not even be Torx. Unless you have a precisely fitting screwdriver bit, press hard in order to prevent it slipping and stripping the head. If you do so, you may be able to remove the screw with a flat bladed screwdriver bit.

Image 1/1: On reassembly, very gently pull these connectors' ribbon cables in order to gain sufficient slack that you can reconnect the connectors. Feed these ribbons back where they came from as you lower the motherboard, taking great care that they don't become disconnected again, otherwise the screen won't work.
  • Lift the motherboard from the left hand end. There are two connectors under the right hand end which you can then lift off.

  • Gently lift the battery connector off the two metal pegs on either side.

  • The battery is held on with a strong adhesive. Lift it very gently with spudgers in order to pry it loose.

    • This step will take time and patience. Don't rush it. The best way is to apply firm but gentle pressure at several points along one edge. Nothing may seem to happen, but the adhesive will gradually be giving. Once you can get a spudger underneath you can apply pressure more locally. On no account apply a hard or sharp tool directly to the battery.

Between step 8 and 9, what tool do you need to use for the 2 screws that the battery connector is hold on to the kindle? I have tried with t2 to t5 and it won't help. Any suggestions?

do you need any glue to put it back together?

The instructions in this guide missed a number of steps and generally left quite a lot to be desired. I've substantially updated the text but some of the pictures could also do with revising or replacing.

where do I get a replacement battery to replace my old one with? There is no mention of where to get a replacement battery not in the parts list or in the guide as the battery appears to be made just for the kindle please help.

Look on eBay. You can get everything on eBay. But beware - a lot of lithium batteries sold online are poor quality. Try and find a seller with a good reputation for selling tablet parts and batteries in particular and who will definitely give a refund if you get a bad one.

Having trouble getting the screen to turn on after reassembly. It will make noises and the buttons seem to work properly but I can't get anything on the screen. Any way that the ribbon cables can get pinched and cease to work?

I've made sure I had good connections on both cables below the motherboard.

Any suggestions or similar experiences?

I used this guide as well as a YouTube video to help repair my Kindle (replace the battery.) Thank you so much!! Even though this was a "rough" guide, it was still very helpful. I found it easy to follow, and was happy to complete the whole thing without damaging the screen at all!! The battery was a total nuisance (shame on Amazon for making it SO difficult to remove!!)
