In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

KINDLE FIRE HD 8.9 – HOW TO REPLACE THE BATTERY

Kindle Fire HD 8.9 – How to replace the battery

BATTERY REPLACEMENT PROCEDURE 
Remove the SIM card tray (if present in your model).
Insert a large plastic opening tool next to the Kindle's headphone jack.
Make sure the notch on the plastic opening tool is facing the back of the Kindle.
Move the plastic opening tool evenly around the Kindle, separating the two halves.
Be careful not to completely separate the rear cover. There are two delicate flex cables that connect the display assembly to the motherboard.
Set the Kindle down on the rear case.
Holding the display assembly near the camera, carefully open the display assembly up to about 90 degrees from the rear case.These images show the Kindle laying flat. In order to prevent damage to the flex cables, keep the Kindle open at 90 degrees while disconnecting the display assembly.
Lift the retaining flap on the ZIF connector of the upper flex cable.
Gently pull the cable out of its socket.
This flex cable is delicate. Be careful not to crease or bend it while working.
Lift the retaining flap on the ZIF connector of the lower flex cable.
Gently pull the flex cable from its socket.
This flex cable is delicate. Be careful not to crease or bend it while working.
Separate the display assembly from the rest of the device.
When reassembling the device, align the two halves of the case before connecting the flex cables.
Remove the following sixteen screws from the metal midframe on the rear of the device:
One 3 mm Phillips screw from each corner
Four 3 mm Phillips screws surrounding the camera
Eight 3 mm Phillips screws from the body of the midframe
Carefully remove the metal midframe.
For easier handling, position the Kindle as shown.
Lift up on the silver ends of the black flex cable that lays across the battery.
Gently pull the black flex cable from the battery.
Disconnect the orange button cable from its socket on the motherboard.
Don't remove the button from the device. It is adhered to the case and may tear during removal.
Starting at the outside edge of the battery, use the flat edge of a spudger to separate the battery from the rear of the device.

Work carefully. Excessive force on battery may cause it to bend, break, or crack.
Move the spudger along each side of the battery, prying upwards with even pressure.
As the adhesive releases, push the spudger further underneath the battery.
Once half of the battery is detached, pry the other half in the same manner.
Remove the battery assembly from the Kindle.
