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.

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.

an isolation transformer. However, the use of isolation

transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.
(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.
(4) The input voltage of the receiver must keep 100-220V~,

50/60Hz.
(5) The receiver must be operated for about 15 minutes prior

to the adjustment.

O After RGB Full white HEAT-RUN Mode, the receiver must

be operated prior to adjustment.

O Enter into HEAT-RUN MODE

1) Press the POWER ON KEY on R/C for adjustment.

2) OSD display and screen display PATTERN MODE.

[ Set is activated HEAT-RUN without signal generator in

this mode.
[ Single color pattern(RED/BLUE/GREEN) of HEAT-RUN

mode uses to check PANEL.

Caution) If you turn on a still screen more than 20 minutes,

(Especially digital pattern, cross hatch pattern) after
image may be occur in the black level part of the screen.

3. Channel memory

3-1. Setting up the LGIDS

4) Start LGIDS.

3-2. Channel memory Method

1) Select “PDP” and “Hurricane” on Model dialog. And check
your connection in Communication dialog. (If your
connection is ‘NG’, then set your PORT.(COM1,2,3,...)
correctly.)

2) Connect RS-232C cable and turn on the power.( Use the
general RS-232C Serial Cable)
(If your connection has completed, you can see “Ready”.)

[ If your set is not an end products but only a board, you

have to make your board to Stand-by state (LED_R). And
you have to Download in Stand_by power state.

3) Select proper CH_memory file(*.nvm) for each model at
[NVRAM Download] $ [Write Batch]
Next, select proper binary file(*.bin) including the CH
information for each model at [NVRAM File].

File name : H2_CH_Memory_RZ.nvm

4) Click the [Download] button.
It means the completion of the CH memory download if all
items show ‘OK’ and Status is changed by ‘PASS’ at the
lower right corner of the window.

5) If you want to check whether the CH information is
memorized correctly or not, click the [Verify] button.
And then compare NVRAM File(*.bin) with the CH
information downloaded.

2) As below Fig.17, Supply 216Level (85 IRE) full screen
pattern to Video input.
(50PC1RR-ZL : AV3/AV4, Press the Front AV key->AV4)

3) Press the TV/AV KEY on R/C for converting input mode.

4) Set the PSM to Standard mode in Picture menu.

5) Enter the White Balance adjustment mode by pressing the
IN-START key twice(White Balance) on R/C.

6) 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.

7) Adjust Only High Light with R Gain/ B Gain using F/G
(VOL+/-) key on R/C.

8) Adjust it until color coordination becomes as below.

(Initially, R/G/B gain and R/G/B offset values are fixed as below

Red Gain : 82, Green Gain : 80, Blue Gain : 86
Red Offset : 7F, Green Offset : 7E, Blue Offset : 82)

Brightness : High Light : 80 ± 20cd/m2
Color-Coordinate : High Light : X : 0.285 ± 0.003

Y : 0.290 ± 0.003

Color Temperature : 9,300°K ± 500°K

9) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
