SAFETY PRECAUTIONS 

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 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. 

IMPORTANT SAFETY NOTICE 

- 3 - 

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.

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 DDC adjust 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.

12-5. Adjustment of White Balance 

(For Manual adjustment) 

- Adjustment mode : Two modes of Cool (Dynamic) and 

Warm(Mild). 

(Medium data is automatically calibrated by the cool data) 

- Color analyzer(CA110, CA210) should be used in the 

calibrated ch by CS-1000.(PDP : CH10) 

- Operate the zero-calibration of the CA-110 or CA-210, then 

stick sensor to the module when adjusting. 

- For manual adjustment, it is also possible by the following 

sequence. 

(1) Select RF no signal by pressing “POWER ON” key on 

remote control for adjustment then operate heat run more 

than 15 minutes. 

(If not executed this step, the condition for W/B will be differ.) 

(2) Changing to the av mode by pushing the input or front av 

key.(av mode : av1 or av2 or av3) 

(3) Display the internal pattern of the VCT-Pro IC by pushing 

the IN-START. 

(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 Gain / B Gain using F/G (VOL+/-) key on R/C. 

(6) Adjust two modes of Cool(Dynamic) and Warm(Mild) as 

below figure. 

(Fix the one of R/G/B and change the others) 

1. Push the one time the in-start key : Dynamic(Cool) 

2. Push the two more the in-start key : Mild(Warm)

* Refer to the below case to know what value is fixed. 

* CASE 

- First adjust the coordinate much away from the target 

value(x, y). 

1) x, y > target 

(1) Decrease the R, G. 

2) x, y < target 

(1) First decrease the B gain. 

(2) Decrease the one of the others. 

- In case of decreasing the x, decreasing the R : fix G 

- In case of decreasing the y , decreasing the G : fix R 

3) x > target , y < target 

(1) First decrease B, so make y a little more than the target. 

(2) Adjust x value by decreasing the R. 

4) x < target , y > target 

(1) First decrease B, so make x a little more than the target. 

(2) Adjust x value by decreasing the G. 

(7) When adjustment is completed, Exit adjustment mode 

using EXIT key on R/C. 

13. Input the Shipping Option Data 

(1) Push the ADJ key in a Adjust Remote control. 

(2) Input the Option Number that was specified in the BOM, 

into the Shipping area.
