Alignment and Adjustments
Samsung Electronics 4-1
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, set PVA to
40 (factory mode) and set SC as follows.
14 inch : 0
20 inch : 9
21 inch : 9
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→ DISPLAY→MENU→MUTE
→POWER ON.
2. The “SERVICE (FACTORY)” message will be
displayed. The Service Mode has four compo-
nents: ADJUST, OPTION 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>SDL>STT>SSP>PDL>
NDL>PSR>NSR>AGC>VOL>LCO>TXP
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.
4-2-2 Main Adjustment Parameter
NOTE : PVS,PVA, PHS, parameters must be aligned using the 50Hz vertical-field rates.

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.
4-2-4 RESET
The Reset Mode is used during factory inspection.
Function Reset:
1. Picture Custom
2. Auto Volume Off
3. Color System Auto (option)
4. Sound System D/K (option)
5. Blue Screen Off
6. Low Noise AMP Off (option)
7. Volume 10
8. CH. Skip Erased
9. CH. Lock Off
10. Timer Off
