SAFETY PRECAUTIONS IMPORTANT SAFETY NOTICE Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

General Guidance

Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.

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 1W), keep the resistor 10mm away from PCB.

Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF 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 0.5mA. 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.

Leakage Current Hot Check circuit Keep wires away from high voltage or high temperature parts.

AC Volt-meter

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 1MΩ and 5.2MΩ. 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.

2. Notice 2.1 Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument. 2.2 Adjustment must be done in the correct order. 2.3 The adjustment must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation. 2.4 The input voltage of the receiver must keep 100~220V, 50/60Hz. 2.5 Before adjustment, execute Heat-Run for 15 minutes at RF no signal.

5. Adjusting the White Balance

6. Adjustment of White Balance

5.1 Purpose and Principle for adjustment of the color temperature - Purpose : Adjust the color temperature to reduce the deviation of the module color temperature. - Principle : To adjust the white balance without the saturation, (Fix the one of R/G/B gain to C0 and decrease the others.)

5.2 Adjustment mode : Two modes of Cool and Warm (Medium data is automatically calibrated by the Cool data) O Required Equipments - Remote controller for adjustment - Color Analyzer : CA100+ or CA-210 or same product LCD TV( ch : 9 ), - Auto W/B adjustment instrument(only for Auto adjustment)

5.3 Connecting diagram of equipment for measuring (For Automatic Adjustment)

• Adjustment mode : Two modes (Cool and Warm) (Medium data is automatically calibrated by the Cool data) • Color analyzer(CA100+, CA210) should be used in the calibrated ch by CS-1000 (LCD : CH9, PDP : CH10) • Operate the zero-calibration of the CA100+ or CA-210, then stick sensor to the module when adjusting. • For manual adjustment, it is also possible by the following sequence. 1) Select white pattern of heat-run by pressing "POWER ON" key on remote control for adjustment then operate heat run longer than 15 minutes. (If not executed this step, the condition for W/B may be different.) 2) Push "Exit" key. 3) Change to the AV mode by remote control.(Push front-AV or Input key) 4) Input external pattern(85% white pattern) 5) Push the ADJ key two times (entering White Balance mode) 6) Stick the sensor to the center of the screen and select each items (Red/Green/Blue Gain and Offset) using / (CH +/-) key on R/C.. 7) Adjust R/ G/ B Gain using / (VOL+/-) key on R/C. 8) Adjust two modes (Cool and Warm) (Fix the one of R/G/B and change the others) 9) When adjustment is completed, Exit adjustment mode using EXIT key on R/C.

(1) Enter the adjustment mode of DDC - Set command delay time : 50ms - Enter the DDC adjustment mode at the same time heat- Maintain the DDC adjustment mode with same condition of Heat-run -> Maintain after AC off/on in status of Heat-run pattern display) (2) Release the DDC adjustment mode - Release the adjust mode after AC off/on or std-by off/on in status of finishing the Hear-run mode - Release the Adjust mode when receiving the aging off command(F3 00 00) from adjustment equipment - Need to transmit the aging off command to TV set after finishing the adjustment. - Check DDC adjust mode release by exit key and release DDC adjust mode (3) Enter the adjust mode of white balance - Enter the white balance adjustment mode with aging command(F3, 00, FF) * Luminance min value is 200cd/ß≥ in the cool mode( For LCD)
