REPAIRING AND NOT THROWING AWAY

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.

MOTOROLA ATRIX 4G – HOW TO REPLACE THE SPEAKER

Motorola Atrix 4G – How to replace the Speaker

Motorola Atrix 4G
Pry the rear cover from the back of the phone.
Insert a spudger or plastic opening tool into the small notch at the base of the battery.
Lift the battery out of the phone.
Remove the four 5.0 mm T5 Torx screws from the corners of the phone.
Remove three 5.5 mm T5 Torx screws from the back of the phone.
Lift up the black rubber flap near the SD card slot.
Remove the single 5.5 mm T5 Torx screw beneath the flap.
Do not attempt to loosen the screws with too much force. These screws are small, and easily stripped.
Remove the back case of the phone by gently lifting the tabs located on top of the phone near the lock button.
Use the case opener or spudger in these small areas because the plastic tabs can be easily broken.
Lift the tabs located on the bottom of the phone to continue removing the back cover.
Slide an opening tool between the gap from the back of the case to the front.
After separating the sides, make sure there is a noticeable gap between the back case and the rest of the phone.
After detaching the tabs and sliding down the sides, there should be a noticeable gap between the front and back cases.
Carefully separate the back case from the rest of the phone by lifting it away from the phone.
Do not completely remove the case from the rest of the phone. The antenna is connected to both cases.
Disconnect the antenna from its housing on the motherboard by gently lifting beneath it.
Ease the antenna from out of its guide along the side of the phone
Once the antenna is detached, remove the back case and the antenna from the phone
The antenna is soldered to the back case. Do not pull with too much force.
To remove the motherboard, first dislodge the right side of the motherboard, where the external connections are located, from the rest of the phone.
This can be done by placing a spudger in between the two ports on the phone, between the black plastic and motherboard, and prying out.
The motherboard should be able to be easily lifted upwards after dislodging it.
If the white rubber piece moves, replace it where it came from upon reassembly.
First, several connections must be disconnected to completely separate the motherboard from the rest of the phone.
The connection highlighted with a red box must be pulled down instead of out.
Using the spudger tool, separate the two connections on the motherboard highlighted with orange circles by pulling them out.
The black switch on top of this connection acts as a lock. Push it forwards to unlock the connection.
After disconnecting the motherboard, there should be five distinct and separate parts of the phone: back cover, back case, front case, battery, and motherboard.
In order to get to the top speaker, first remove the rubber cover located directly over the speaker.
The orange adhesive strip needs to be peeled off in order to remove the top speaker. This can be done using fingernails or the spudger tool.
Using the spudger, lift up from under the top speaker and it should slide easily out of place.
Be careful when removing top speaker out of its housing because it is still connected to the phone. You must undo the connection indicated with the orange circle before complete removal.
To undo the connector lift the black flap up - edge closest to the speaker - then the cable slides out
