SAFETY PRECAUTIONS
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in theSchematic 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 preventX-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.
General Guidance
An lsolation Transformer should always be used during theservicing of a receiver whose chassis is not isolated from the ACpower line. Use a transformer of adequate power rating as thisprotects the technician from accidents resulting in personal injuryfrom electrical shocks.
It will also protect the receiver and it's components from beingdamaged by accidental shorts of the circuitary that may beinadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace itwith the same specified type.
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.
Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source, connect anelectrical jumper across the two AC plug prongs. Place the ACswitch in the on positioin, connect one lead of ohm-meter to the ACplug prongs tied together and touch other ohm-meter lead in turn toeach exposed metallic parts such as antenna terminals, phonejacks, etc. If the exposed metallic part has a return path to the chassis, themeasured resistance should be between 1MΩ and 5.2MΩ. When the exposed metal has no return path to the chassis thereading must be infinite.An other abnormality exists that must be corrected before thereceiver 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 1.5K/10watt resistor in parallel with a 0.15uF capacitorbetween a known good earth ground (Water Pipe, Conduit, etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using AC voltmeterwith 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat AC voltagemeasurements for each esposed metallic part. Any voltagemeasured must not exceed 0.75 volt RMS which is corresponds to0.5mA.In case any measurement is out of the limits sepcified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.

6-3. White Balance Adjustment MethodBasically it uses the internal pattern but when internal patternis not possible, you can select HDMI input for adjustment.Through the option at the most bottom part of the Ez AdjustMenu 7.White Balance menu, you can select NONE, INNERand HDMI, and the default is set to INNER. When theadjustment cannot be done with the internal pattern, you canselect HDMI input for adjustment.
For manual adjustment, press the ADJ KEY of the adjustmentR/C to enter Ez Adjust 7.White-Balance, and the pattern isautomatically displayed. (When you set the Option to INNER,the default is always set to INNER)
(1) Connect the set according to the internal pattern or HDMIinput in accordance with measuring device connectiondiagram.
(2) Set the Baud Rate of RS-232C to 115200. It is set to115200 as default.
(3) Connect the RS-232C Cable to the set.(4) Connect the HDMI Cable to the set. (Limited to the set with
HDMI option)(5) Select and adjust the model applicable to PU82C chassis
from the adjuster.

(4) Execute a Zero Calibration for CA-210 and put it atdistance of less than 10Cm from the PDP module surfacecenter during the adjustment.
(5) Select ‘7. White-Balance’ of ‘Ez - Adjust’ by pressing theADJ KEY on the Service R/C. Then enter adjustment modeby pressing the Right KEY (G) .(The internal pattern of full white appears by pressing G)
(6) The adjustment is conducted in three levels of colortemperature; COOL, MEDIUM, and WARM.
-When R Gain is Fixed at Default value(192)Adjust G gain and B gain with decreasing Default valuesfrom 192
-When B Gain is Fixed at Default value(192)Adjust R gain and G gain with decreasing Default valuesfrom 192
-When G Gain is Fixed at Default value(192)Adjust R gain and B gain with decreasing Default valuesfrom 192
One of R/G.B Gain should be fixed at 192 and adjust twoGain Value with decreasing the Default values from 192.
(7) Use the Vol. +, - key for adjustment.(8) When the adjustment is completed, press the ENTER (Á
