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!

Then slide the SIM and Micro-SD cards out of their trays (marked with an orange arrow).
Insert the plastic opening tool in the seam of the smartphone to create separation between the loudspeaker and the phone. You can now carefully remove the loudspeaker from
the LG G3.
Next, use the pry tool or spudger to separate the rear housing/frame from the smartphone’s display assembly. Work your way around the perimeter of the handset until all of the clips have been released and the rear housing/frame is removed from the G3.
How to remove Power & Volume Buttons
Utilize the heat gun or a blow dryer to soften the adhesive securing the power and volume button assembly to the rear housing/frame.
Now, use the fine-tip curved tweezers to gently pry the power and volume button assembly up from the adhesive and remove it from the LG handset.
How to remove Motherboard
Locate the four wafer connections (marked with orange rectangles). Use the fine-tip curved tweezers to release the connections from their sockets.

Separating the display assembly from the frame is only recommended if the G3 has a CRACKED or DAMAGED screen that needs to be replaced.
Use the heat gun or a blow drier to soften the adhesive securing the display assembly to the frame/bezel of the LG G3.
To separate the display assembly from the frame/front housing, utilize one of the screwdrivers, and through the front-facing camera hole carefully push the damaged display assembly away from the LG G3’s frame.
