1. INTRODUCTION
1.1 Purpose
This manual provides the information necessary to repair, calibration, description and download the features of this model.
1.2 Regulatory Information
A. Security
This material is prohibited to share and release to unauthorized person, in accordance with the regulations, LG Electronics, Civil / criminal
responsibility in accordance with the relevant provisions violate.
B. Precautions for repair
•
In case of Disassembly or Assembly to repair product, be careful of a product failure caused by RF signals and Static electricity.
•
When using Magnetic tool for the Phone's SVC repair, you should check affect the Electric parts according to effect of Magnet.
•
When fastening the screw, be careful not to damage the head of screw and even product.
C. Attention
Boards, which contain Electrostatic Sensitive Device (ESD), are indicated by the
sign.
Following information is ESD handling:
•
Service personal should ground themselves by using a wrist, strap when exchange system board.
•
When repair are made to a system board, they should spread the floor with anti-static mat which is also grounded.
•
Use a suitable, grounded soldering iron.
•
Keep sensitive parts in these protective packages until these are used.
•
When returning system board or parts like EEPROM to the Factory, use the protective package as described.

Circuit 1. u-SDCARD SIM Combo for QMC /w Low Detection
+3V0_MTK_USIM2
Note 1. +2V95_SD_PULL_UP ( 1.8 or 2.95V ) switches automatically per inserted SD Card version
For example, SD card Version 2.0 = 2.95V, Version 3.0 = 1.8V
Caution ! - According to MSM8960, APQ8064 BackPowering issue, +2V95_SD_PULL_UP was Always on during sleep mode.
However, It is possible for MSM8974, MSM8x10 .. to be turned off, so, FET circuit to turn off it is not needed any more.
Note 2. +2V95_SD_VCC is SD/MMC Power

MC-C04582-14 : Below items should be satisfied
1. SD_DETECT Pull-up or Pull-down
2. Data/CMD line should be needed Pull-up resistor
( If chipset has internal Pull-up, comment it on circuit )
3. Use under total 10pF Capacitance on each line ; Data [0:3], CMD - Cap. TVS diode, varistor
( on other line, We recommend 10pF capacitance and use under 30pF capacitance )
4. CAP,Varistor should Place close to connector
(DGMS Guide)
MC-C04581-13 : Below items should be satisfied
1. SIM_DATA pull-up resistor
2. Use under 33pF (Cap_Varistor) on each signal line
3. When routing, SIM_DATA, SIM_CLK should be seperated
4. CAP,Varistor should Place close to connector

MC-C05446-7 : Below items should be satisfied
1. Power of SD card should use independant Power source just like LDO/PMIC which can turn off it.
2. Per chip type which support SD card should manage current capacity.
( In case of High speed mode, SD Card Power should get margin of 200mA )
3. Do not connect serial component to SD card power, voltage drop can arise at Power line.
