4. Alignment and Adjustments

4-1 Preadjustment

4-1-1 Factory Mode

1. Do not attempt these adjustments in the Video

Mode.

2. The Factory Mode adjustments are necessary

when either the EEPROM (IC902) or the CRT

is replaced.

3. Do not tamper with the “Adjustment” screen

of the Factory Mode menu. This screen is

intended only for factory use.

4-1-2 When EEPROM (IC902) Is Replaced

1. When IC902 is replaced all adjustment data

revert to initial values. It is necessary to

re-program this data.

2. After IC902 is replaced, warm up the TV for

10 seconds.

4-1-3 When CRT Is Replaced

1. Make the following adjustments AFTER set-

ting up after setting up purity and conver-

gence :

White Balance

Sub-Brightness

Vertical Center

Vertical Size

Horizontal Size

Fail Safe (This adjustment must be the last

step).

2. If the EEPROM or CRT is replaced and set SC

as 20(factory mode).

4-2 Factory/Service Mode

4-2-1 Procedure for the “Adjustment” Mode

1. This mode uses the standard remote control.

The Service Mode is activated by entering the

following remote-control sequence :

(1) DISPLAY → FACTORY.

(2) STAND-BY → MUTE →1 →8 →2

→POWER ON.

2. The “SERVICE (FACTORY)” message will be

displayed. The Service Mode has four compo-

nents: ADJUST, OPTION , G2-ADJUST and

RESET.

3. Access the Adjustment Mode by pressing the

“VOLUME” keys ( Up or Down). The adjust-

ment parameters are listed in the accompany-

ing table, and selected by pressing the CHAN-

NEL keys ( , ).

4. Selection sequences for the all system:

DOWN or UP key:

SCT>SBT>BLR>BLB>RG>GG>BG>VSL>VS>

VA>HS>SC>CDL>STT>AKB>FS>NDL>

LBS>NSR>SCBT>VOL>CAP>HBS>RP00>

RP01>FMWS>AGC1>OMD>SCL>PWL>

MUS>AGC>DSK>DVDB

5. The VOLUME keys increase or decrease the

adjustment values (stored in the

non-volatile memory) when Adjustment Mode

is cancelled.

6. Cancel the Adjustment Mode by re-pressing

the “FACTORY” or “Power OFF” keys.

Alignment and Adjustments

4-4 Samsung Electronics

4-3 Other Adjustments

4-3-1 General

1. Usually, a color TV needs only slight touch-

up adjustment upon installation. Check the

basic characteristics such as height, horizontal

and vertical sync and focus.

2. The picture should have good black and white

details. There should be no objectionable

color shading; if color shading is present, per-

form the purity and convergence adjustments

described below.

3. Use the specified test equipment or its equiva-

lent.

4. Correct impedance matching is essential.

5. Avoid overload. Excessive signal from a sweep

generator might overload the front-end of the

TV. When inserting signal markers, do not

allow the marker generator to distort test

results.

6. Connect the TV only to an AC power source

with voltage and frequency as specified on the

backcover nameplate.

7. Do not attempt to connect or disconnect any

wires while the TV is turned on. Make sure

that the power cord is disconnected before

replacing any parts.

8. To protect against shock hazard, use an isola-

tion transformer.

4-3-2 Automatic Degaussing

A degaussing coil is mounted around the pic-

ture tube, so that external degaussing after

moving the TV should be unnecessary. But

the receiver must be properly degaussed upon

installation.

The degaussing coil operates for about 1 sec-

ond after the power is switched ON. If the set

has been moved or turned in a different direc-

tion, disconnect its AC power for at least 30

minutes.

If the chassis or parts of the cabinet become

magnetized, poor color purity will result. If

this happens, use an external degaussing coil.

Slowly move the degaussing coil around the

faceplate of the picture tube and the sides and

front of the receiver. Slowly withdraw the coil

to a distance of about 6 feet before removing

power.
