Samsung Galaxy S III Motherboard Assembly Replacement

Difficulty

Moderate

Steps

Time Required

No estimate

Introduction

Prereq only.

Tools

Step 1

Use a plastic opening tool to pry the front-facing camera connector from its socket on the motherboard.
Do not try to remove the front-facing camera just yet. Its cable is still routed beneath the motherboard assembly to the ambient light sensor.

Step 2

Disconnect the digitizer cable by gently prying its connector up from its socket on the motherboard.

Step 18 says the front digitizer connector, but later calls it the earpiece/buttons/ambient light sensor ribbon cable.

Is the Digitizer connector part of the display connector, or is it elsewhere?

It's the volume and speaker

Step 3

Disconnect the display data cable from the motherboard.

Step 4

Pry the Wi-Fi antenna cable connector up from its socket on the motherboard.
Gently move the cable out of the way of the motherboard.

Be very careful,as it is very easy to break the connector off the motherboard.

Has anyone tried just folding the motherboard back to the left after removing all the screws WITHOUT disconnecting the wi-fi antenna? I'm just a little worried about this one step.

Folding the motherboard back without disconnecting the WiFi antenna worked for me! :)

I broke the WiFi antenna connector bit off motherboard. How do I fix it?

Step 5

Remove the single 3.0 mm Phillips screw securing the motherboard to the front panel assembly.

Step 6

Carefully lift the bottom of the motherboard assembly away from the front panel assembly.
Remove the motherboard assembly from the front panel assembly, minding any cables that may snag on it.

When reassembling your device, there can be a problem with connecting display data cable to the motherboard. I fixed display data cable on the motherboard before mounting motherboard: it gave me some freedom and simplified positioning of data cable on the motherboard

If I am not mistaking, there is a screw also on the motherboard needs to be removed before removing motherboard from the assembly
