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.

How to remove Loud Speaker

Locate and remove the twelve small Phillips screws (#00) that secure the loud speaker and rear housing/protective cover to the motherboard (marked with orange circles).

With the small Phillips screws removed you can now pry up and remove the loud speaker as well as the rear housing/protective cover over the motherboard.

How to remove Front-Facing Camera

Release the front-facing camera’s flex cable connection from the motherboard. You can now pry up and remove the front-facing camera from the LG G2.

How to remove Dock Connector & Headphone Jack Assembly

Locate the two coaxial cable plugs. Use the tweezers to pry up and release the two plugs from their connectors (marked with orange circles).
Locate the five wafer plug connectors. Use the tweezers or the nylon spudger to release the five plugs from their connectors (marked with white rectangles).

There is an extended portion of the G2 dock connector assembly located on either side of the battery. Use the nylon spudger to peel up the extended portion of the assembly from the adhesive holding it in place.

The bottom portion of the dock connector & head phone jack assembly also has adhesive holding it in place. Use the nylon spudger to pry up and remove the dock connector assembly from the LG G2.

Be mindful of the microphone ribbon cable that is secured by a rubber grommet in its housing (marked with orange arrow).

Now, maneuver the motherboard up and out of the G2 smartphone.

How to remove Rear-Facing Camera

Use the fine tip curved tweezers to pry up and remove the rear-facing camera from the LG G2. Be careful as it is secured in place with a small amount of adhesive.

How to remove Earpiece Speaker Assembly

The sensor flex cable is also secured in its housing with adhesive. Use the fine tip curved tweezers to pry up and remove the sensor flex cable from the LG G2.

How to remove Display Assembly (LCD & Touch Screen)

The display assembly (LCD & touch screen) are fused together and secured to the frame /front housing of the LG VS980 using a good amount of adhesive. It will require heat, and patience, to separate the display assembly from the frame.
This procedure is only recommended on a G2 with a DAMAGED display that requires replacement. Use the heat gun or blow drier to heat the adhesive securing the display assembly (LCD & digitizer) to the G2’s frame/ front housing. The heat will loosen the adhesive securing the parts together.

To separate the display assembly from the frame/front housing, utilize one of the screwdrivers and through the front-facing camera hole, while securely gripping the sides of the G2 frame, carefully push the damaged display assembly away from the LG G2’s frame.
You can now use the plastic opening tool to continue working around the entire G2 display assembly slowly separating it from the frame/front housing.
