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.

LG G PAD 8.3 LG TABLET - – DISASSEMBLING PROCEDURE – HOW TO REPLACE THE MOTHER BOARD

LG Tablet - LG G Pad 8.3 – Disassembling procedure – How to replace the mother board

With the tablet face down, pull out the SD card slot cover.
Using a Philips #000 screwdriver, remove the 3mm screw in the SD card slot.
Insert a plastic opening tool in the small crevasse between the screen and the back.
Pry the screen away from the back panel.
Repeat this on each edge of the device.
We found it helpful to leave multiple plastic opening tools wedged in the crevasse to prevent it from closing.
This requires heavy force. The back of the device is attached with adhesive. If the back panel is too hard to remove, use the Opener.
After using the plastic opening tools, pry open the device with your hands, removing the back panel from the screen.
Remove the four 3 mm Phillips screws that hold down the speaker.
These screws are very small so make sure to keep track of them.
Use your fingers to remove the speaker.
With a Philips screwdriver #000 unscrew the 3mm screws at the corners of the battery.
Using a spudger or plastic opening tool, disconnect the ribbon cable from the right side of the device, where it is attached with adhesive.
These images use a metal spudger, which has the potential to damage the device. Use a plastic opening tool or standard spudger instead.
Use the Philips screwdriver #000 to remove the 3mm screws at the bottom of the tape.
Remove the yellow tape from the device.
Unhook the battery from where it is attached at the top of the device.
Unhook the small yellow ribbon on top of the motherboard.
Remove all the 3mm silver screws and the 2mm black screws on the motherboard and carefully lift it out of the device.
Use a plastic opening tool to lift the motherboard out of the device.
These images use a metal spudger, which has the potential to damage the device. Use a plastic opening tool or standard spudger instead.
