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 X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

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 monitor 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. Keep wires away from high voltage or high temperature parts. Due to high vacuum and large surface area of picture tube, extreme care should be used in handling the Picture Tube. Do not lift the Picture tube by it's Neck.
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 1.5K/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

AC Volt-meter

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 1M and 5.2M. 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.

9. Adjustment of White Balance
9-1. Purpose and Principle for Adjustment of the Color Temperature
(1) Purpose: Adjust the color temperature to reduce the deviation of the module color temperature. (2) Principle : To adjust the white balance without the saturation, Fix the one of R/G/B gain to C0 and decrease the others. (3) Adjustment mode: Two modes of Cool and Warm (Cool data is automatically calibrated by the Medium data)
(1) Enter the adjustment mode of the white balance - Enter the white balance adjustment mode at the same time heat-run mode when pushing the power on by power only key - Maintain the white balance adjustment mode with same condition of Heat-run - Maintain after AC off/on in status of Heat-run pattern display (2) Release the white balance 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(F00) from adjustment equipment) (3) Enter the adjust mode of white balance - Enter the white balance adjustment mode with aging command(F3, 00, FF)

9-2. Required Equipment

(1) Remote controller for adjustment (2) Color Analyzer : CA-100+ or CA-210 or same product - PLASMA TV(ch : 10) (3) Auto W/B adjustment instrument(only for Auto adjustment) - Do the white balance adjustment under the 10LUX [ Notice: When using the Color Analyzer with PDP, recommend the CA-100 more than CA-210. If CA-100 can not available, it is also good to use the CA-210. (4) PC (for communication through RGB) (5) Pattern Generator (MSPG-925FA etc.) -Before white balance, press the ADJ key 2times and do the reset like Fig. 4 -To enter White-balance mode, press the ADJ key 2times. [ Caution: System control Host should be DDC for adjustment.
Color Temperature & Color Coordinates Setting - When adjusting the Color Temperature, Color Analyzer CA210(Matrix should be corrected through CH10 of CS-1000) should be used. When CA-210 have used, it dont need to fit the CH10. - Adjust the Color Temperature based below adjustment color coordinates. Target Value CA-210(PDP : CH10), CA-100(PDP) (Standard color coordinate and temperature when using the CA-100+ or CA210 equipment) Mode MEDIUM WARM Color Coordinate x y 0.2850.002 0.2930.002 0.3130.002 0.3290.002 Temp 9,300K 6,500K uv 0.000 0.003

9-4. Adjustment of White Balance for Manual Adjustment
Adjustment mode: Two modes of Medium(Vivid) and Warm (Cool data is automatically calibrated by the Medium data) - Equipment : 1) Color analyzer(CA100+, CA210) should be used in the calibrated ch by CS-1000(.(LCD : CH9, PDP : CH10) 2) Adjustment remocon - For manual adjustment, it is also possible by the following sequence. Operate the zero-calibration of the CA-100+ or CA-210, then stick sensor to the module when adjusting. (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. (recommend) (If not executed this step, the condition for W/B will be different) (2) Changing to the AV mode by remote control.(Push frontAV) (3) Input external pattern(85% white pattern). (4) Stick sensor to center of the screen and select each items (Red/Green/Blue Gain and Offset) using D/E(CH +/-) key on R/C. (5) Adjust R/ G/B Gain using F/G(VOL +/-) key on R/C. (6) Adjust two modes of Medium(Vivid) and Warm as below figure. (Fix the one of R/G/B and change the others) 1) Default : Medium(Vivid) 2) Push the VOL + key twice : Warm Mode MEDIUM WARM Color Coordinate x y 0.2850.002 0.2930.002 0.3130.002 0.3290.002 Temp 9,300K 6,500K uv 0.000 0.003
