How to enter service mode, service adjustments – Beko TFT LCD TV – LC and L5C chassis

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”
LC (L5C) SERVICE MENU
Service Menu is entered by pressing 9, 3, 0, 1 key 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 Auto Programming process.

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.

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.
