SAFETY PRECAUTIONS

GENERAL GUIDELINES

1. Always use the manufacturer’s replacement safety

components. The critical safety components marked
with on the schematics diagrams should not be

by other substitutes. Other substitute may create the
electrical shock , fire or other hazards. Take
attention to replace the spacers with the originals.
Furthermore where a short circuit has occurred ,
replace those components that indicate evidence of
overheating.

2. After servicing , see that all the protective devices

such as insulation barriers, insulation papers, shields
and isolation R-C combinations are correctly
installed.

3. When the receiver is not being used for a long time

of period of time , unplug the power cord of the
Adaptor from the AC outlet.

Color TFT LCD Module is very sensitive
both electrically and physically.Users,
therefore, are requested to follow the
“Guidance of handling color TFT LCD
Module”on the followings.

1 — Be careful not to make scratch on the

polarizer.

Surface of polarizer is soft and can be physically

damaged easily.

Please do not touch, push or rub polarizer surface

with materials over HB hardness.

2 — Keep clean the surface.

Please wear rubber glove when touch the surface of
LCD screen. Please use so ft and anti-static material
as cleaner.

3 — Keep out of water.

Water on/in the LCD may cause electrical short or
corrosion. Please wipe out dry or water carefully.

4 — Prevent swift Temperature &

Humidity change.

Instantaneous temperature and/or humidity change
can make dew or ice which cause nonconformance
such as malfunction.

5 High temperature & high humidity

reduce the life-time.

LCD is not proper to be used at high temperature
and high humidity. Please keep specified
temperature and humidity condition.

6 — Keep out of Corrosive Gas.

Corrosive gas effect the polarizer and the circuit
chemically and cause defects accordingly.

7 — Electrostatic discharge can make

Damage

There are electro-static sensitive components such
as CMOS in LCD Module. Please earth human
body when handle the LCD.In addition, please do
not touch the interface connector pin with bare.

8 — Do not operate for a long time under

the same pattern

Operating LCD for a long time under the same
pattern can cause image persistence and can
damage it. Please follow following guidance.

1. Turn the power off when do not use.

2. Change the pattern periodically.

LC (L5C) SERVICE MENU

Service Menu is entered by pressing 9, 3, 0, 1 keys on the remote controller when the Picture icon is
highlighted in the Main Menu.

Service Menu has 3 sub-menus. These are:

• Options

• Adjustments

• Selections.

Navigation through these menus can be done by pressing OK button. Every adjustment made in this
menu is saved automatically.

OPTIONS

Options are adjustments that the user can select On or Off.

• SCART 2

• FAV

• SVHS

• HOTEL MODE

• STAND BY

• MSP CARRIER MUTE

• WSS SCART

• FIRST ATS

SCART 2 / FAV / SVHS

If a source is disabled in the Service Menu, it will be skipped during source switches. If SCART2 is
enabled, SW assumes that the FAV source share the same path as the SVHS source on the HW. If it is
disabled, it is assumed that FAV and SVHS share separate paths. TUNER and SCART1 are enabled by
default.

HOTEL MODE

Enabling Hotel Mode has two effects. First, SETUP menu is no longer accessible by the user. Second,
maximum adjustable volume value is limited to HOTEL VOLUME value. This value can be adjusted in the
ADJUSTMENTS sub-menu of the Service Menu.

STAND BY

If this Option is OFF, the TV will stay in Stand By mode after a Power On. If this Option is ON, the TV will
recall its last stand by status before the Power Off, and switch on from Stand By automatically, if the last
state was ‘Stand by On’.

MSP CARRIER MUTE

If this option is ON, sound processor’s carrier mute functionality will be enabled. The MSP will mute the
sound automatically if the signal quality is bad. Setting this option Off will disable this functionality.

ATS

If this option is set to ON, TV will display Country Selection menu in the next start. After some country is
selected, the user will be prompted for the start of AutoProgramming process.

ADJUSTMENTS

This sub-menu contains numeric adjustments. These items are:

• WHITE R

• WHITE G

• WHITE B

• BRIGHTNESS

• CONTRAST

• COLOR

• PRESCALE FM

• PRESCALE NICAM

• PRESCALE SCART

• HOTEL VOLUME

WHITE R / WHITE G / WHITE B

These are used for color bias adjustment. Unlike other items in the service menu, changes will take effect
immediately.

PRESCALE FM / PRESCALE NICAM / PRESCALE SCART

These are prescale values that will be used for the initialization of the sound processor (MSP), at the next
switch on.

HOTEL VOLUME

This value is used as the volume limit, when the Hotel Mode is on.

SELECTIONS

This sub-menu contains selections.

• TUNER TYPE SAMSUNG / PHILIPS

• TELETEXT NO TEXT / FAST / FAST&TOP

• MSP CLIP REDUCE VOL / REDUCE TONE

TUNER TYPE

One of two supported tuner can be selected from this item. System must be restarted for this change to
take effect.

TELETEXT

NO TEXT: Teletext is totally disabled. TXT/MIX button will not be functional. AUTO picture format mode

will be disabled in RF, F-AV and SHVS modes. Naming and sorting functionality during Autoprogramming
will be disabled.

FAST: TOPtext functionality will be disabled.

FAST&TOP: TOPtext functionality is enabled.

TIMER MODE

If OFF TIMER is selected, the user will be able to enter time of the day info for the TV to switch off. If
SLEEP TIMER is selected, the user can specify some time period, after which the TV will go to stand by
automatically.

MSP CLIP

This selection identifies which method will be used by the sound processor to prevent clipping effects on
volume.

AUTOPROGRAMMING

When the user selects the Autoprogram item in Setup menu, Country Selection menu is opened. The user
must select a country before the Autoprogramming starts. Broadcast system will be selected according to
the country selected.

Broadcast systems according to countries:

BELGIUM BG + L
CROATIA BG
CZECH REP. DK
DENMARK BG
FINLAND BG
FRANCE L + BG
GERMANY BG
GREECE BG
HUNGARY DK
IRELAND I
ITALY BG
NETHERLANDS BG
NORWAY BG
POLAND DK
PORTUGAL BG
SPAIN BG
SWEDEN BG
SWITZERLAND BG + L
TURKEY BG
UNITED KINGDOM I

For countries France, Belgium and Switzerland, autoprogramming is done twice. For Belgium and
Switzerland, first BG channels will be searched, after the search in BG is done, searching will restart for L
standard. If the selected country is France, the sequence of standards is reversed, thus, first L then BG.

TELETEXT LANGUAGES

L5C SW decides which teletext language group will be used for teletext decoding, according to the
country selected for autoprogramming.Teletext languages according to countries:

EAST EUROPE:CROATIA ,CZECH_REP, POLAND

WEST EUROPE: BELGIUM ,DENMARK, FINLAND, UK, FRANCE, GERMANY,

IRELAND ,ITALY ,NETHERLANDS, NORWAY, PORTUGAL,SPAIN, SWEDEN, SWITZERLAND,
HUNGARY

TURKISH-GREEK:GREECE TURKEY

PC MODE

PC mode can be entered by pressing PC button on the remote controller. User can return back to TV
mode by pressing the PC or TV buttons.

After the switching to PC mode, VGA input will be displayed on screen, as soon as the mode (input
resolution and frequency) is determined.

If there is no input from the VGA input, NO SIGNAL dialog will be displayed for 15 seconds. At the end of
this period if there is no signal from VGA input, the TV will go to Sleep State. While in the sleep state, the
TV will keep monitoring the VGA input. If VGA signal is detected, the TV will wake from Sleep State, to PC
mode. Alternatively, the user may select to switch the TV on from Sleep State, just like switching on from
Stand-by. In this case, the set will switch on from TV mode.
