LG LED 55LW980S-ZA TV Service menu General Guidance
An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks.
It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified.
When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1 W), keep the resistor 10 mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Before returning the receiver to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, etc., to be sure the set is safe to operate without damage of electrical shock.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs. Place the AC switch in the on position, connect one lead of ohm-meter to the AC
plug prongs tied together and touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc.
If the exposed metallic part has a return path to the chassis, the measured resistance should be between 1 MΩ and 5.2 MΩ.
When the exposed metal has no return path to the chassis the reading must be infinite.
An other abnormality exists that must be corrected before the receiver is returned to the customer.

Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5 K / 10 watt resistor in parallel with a 0.15 uF capacitor between a known good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which is corresponds to 0.5 mA.
In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.

CAUTION : Before servicing the chassis or enter the Service mode,
Read the safety precautions in service manual.

Circuit Board Foil Repair
Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil to separate from or "lift-off" the board. The following guidelines and procedures should be followed whenever this condition is encountered.
At IC Connections To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board. (Use this technique only on IC connections).
1. Carefully remove the damaged copper pattern with a sharp knife. (Remove only as much copper as absolutely necessary).
2. carefully scratch away the solder resist and acrylic coating (if used) from the end of the remaining copper pattern.
3. Bend a small "U" in one end of a small gauge jumper wire and carefully crimp it around the IC pin. Solder the IC connection.
4. Route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good copper pattern. Solder the overlapped area and clip off any excess jumper wire.
At Other Connections Use the following technique to repair the defective copper pattern at connections other than IC Pins. This technique involves the installation of a jumper wire on the component side of the circuit board.
1. Remove the defective copper pattern with a sharp knife.
Remove at least 1/4 inch of copper, to ensure that a hazardous condition will not exist if the jumper wire opens.
2. Trace along the copper pattern from both sides of the pattern break and locate the nearest component that is directly connected to the affected copper pattern.
3. Connect insulated 20-gauge jumper wire from the lead of the nearest component on one side of the pattern break to the lead of the nearest component on the other side.
Carefully crimp and solder the connections.
CAUTION: Be sure the insulated jumper wire is dressed so the it does not touch components or sharp edges.

LG MODEL 26LX1D-UA SERVICE MODE

CHASSIS AL-04DA

This service code can use for LG 26LX2D-UA 

Applicability
These specifications are applicable for all PDP TV models with an AL-04DA chassis that are manufactured by the Manufacturing Group of the Display Business Division, or any of its related manufacturers.
LG 26LX1D-UA Specifications
This chassis is the non-charging type chassis for which the power unit is insulated. Therefore, the
insulated type transformer is not required but it is recommended that it be used between the power
supply line and chassis input side before running the chassis, in order to protect the adjustment equipment.
Adjustment should be made in the correct sequence.
However, the order can be changed for mass production purposes.
The suggested surrounding temperature is 25±5°C, and suggested relative humidity is 65±10% for the adjustment of the chassis, unless specified.
The input voltage should be maintained at 110V and 60MHz.
The receiver should run for about 15 minutes before starting adjustment, unless specified.
- Run prior operation after receiving 100% White pattern (06CH).
(OR, 9. White Pattern state in Ez-Adjust.)
- How to enter into the White Pattern
1) Press the Power ON key in the adjustment remote control.
2) Or, press the ADJ key on the adjustment remote control to enter into Ez-Adjust and select 9. White
Pattern using CH +/- key. Then, press the OK key to display 100% Full White Pattern.
* In this mode, the SET can be put on HEAT RUN
without a separate signal generator.

Note If you leave the stop image on for more than 20 minutes, you must be careful because an afterimage will appear on the black level section.
(Applies to internal digital pattern (13CH) and cross hatch pattern (09CH) with clear black/white
contrast, in particular).

LG 26LX1D-UA Full assembly process adjustment
<Precaution>
Each PCB assembly must be checked using the check jig set before the full assembly process. (The power PCB assembly can damage the LCD module irreparably.)
Extended Display Identification Data (EDID) and Display Data Channel (DDC) download
Overview
Developed by VESA, the EDID function is designed to support the "plug & play" function, which enables the computer to configure the user environment automatically through communication with the

3.3 ADC Process
"IIC_ SW" must set "0"(After ISP, automatically set "0")
3.3.1 AV(CVBS) Mode Adjustment
3.3.1.1 Auto Gain/Offset Adjustment
Select AV(Video) in Input menu Signal equipment : MSPG925
Output Jack : CVBS Output Voltage : 700 mVp-p (patt # 29 in MSPG925)
Resolution : NTSC J - 720 x 480 @59,94Hz (Model #207 in MSPG925)
Adjust by commanding AUTO_COLOR_ADJUST (0xF1) 0x00 0x00 instruction.
3.3.1.2 Confirmation of adjustment process
We confirm whether "0x01" address of EEPROM "0xA0" is "0xAA" or not.
If "0x01" address of EEPROM "0xA0" isn't "0xAA", we adjust once more in adjustment line by adjust method of 3.2.1.2.
