Activate SAM
To activate SAM, use one of the following methods:
* Press the following key sequence on the remote control transmitter: “062596”, directly
followed by the “INFO/OK” button. Do not allow the display to time out between entries while
keying the sequence.
* Or via ComPair.
After entering SAM, the following items are displayed, with “SAM” in the upper
right corner of the screen to indicate that the television is in Service
Alignment Mode.
How to Navigate
* In the SAM menu, select menu items with the UP/DOWN keys on the
remote control transmitter. The selected item will be indicated. When not all
menu items fit on the screen, use the UP/DOWN keys to display the
next/previous menu items.
With the “LEFT/RIGHT”
keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
– Change the value of the selected menu item.
When you press the MENU button once while in top level SAM, the set will switch
to the normal user menu (with the SAM mode still active in the background).
How to Store SAM Settings
To store the settings changed in SAM mode (except the RGB Align
settings), leave the top level SAM menu by using the POWER button on the remote
control transmitter or the television set. The mentioned exceptions must be
stored separately via the STORE button.
How to Exit SAM
Use one of the following methods:
Switch the set to STANDBY by pressing the mains button on the remote control
transmitter or the television set.
Via a standard RC-transmitter, key in “00” sequence.
Note: When the TV is switched “off” by a power interrupt while in SAM,
the TV will show up in “normal operation mode” as soon as the power is supplied
again. The error buffer will not be cleared.
How to Activate the
Factory mode
To activate the Factory mode, use the following method:
Press the following key sequence on the remote control transmitter: from the “menu/home” press “1999”, directly
followed by the “Back/Return” button. Do not allow the display to time out between entries while
keying the sequence.
After entering the Factory mode, we can see many items displayed, use the UP/DOWN
keys to display the next/previous menu items
How to Exit the Factory
mode
Use one of the following methods:
Select EXIT_FACTORY from the menu and press the “OK” button.
Note: When the TV is switched “off” by a power interrupt, or normal
switch to “stand-by” while in the factory mode, the TV will show up in “normal operation
mode” as soon as the power is supplied again. The error buffer will not be
cleared
Software Upgrading, Error code and Panel Code
Software Upgrading
The following update is for .pkg file.
1.
Rename the file to “upgrade_loader.pkg”
2. Prepare a USB memory.
3. Copy the software to USB flash disk(root directory).
4. Switch off the TV and Insert the USB memory stick that contains the software
update files in one of the TV’s USB 2.0 ports. [Note: It contains USB3.0 port, if connect on it, the software may can’t
be detected.]
5. Switch on the TV. The TV will detect the USB memory s tick automatically.
6. When the TV software is
updated, the TV will turn on again automatically. Remove your USB flash drive.
7. We can enter in CSM or Factory mode to check the current software version.
The
following update is for .upg file.
Ready for F/W Upgrade
1.
Rename the file to “autorun.upg”
2. Prepare a USB memory.
3. Copy the software to USB flash disk(root directory).
4. Switch on the TV and Insert the USB memory stick that contains the software
update files in one of the TV’s USB 2.0 ports
Note the version of this F/W before you change the software file name.
F/W Upgrade
1.
Press [Quick settings], then Choose [Update Software] in the Settings menu
2. Choose [Local Updates], and then press OK.
3. Select the file that you downloaded and press OK
4. Choose [Update], and then choose [Start]
Check the SW version
1.
After burning software, TV will restart
2. Press “123654”, enter Customer service mode to check if the software version is
correct.
Caution: Please make sure that software upgrade is finished before unplug the
USB and AC power.
Error Code
Error codes are required
to indicate failures in the TV set. In principle a unique error code is
available for every:
• Activated (SW) protection.
• Failing I2C device.
• General I2C error.
The last five errors, stored in the NVM, are shown in the Service menu’s. This
is called the error buffer.
The error code buffer contains all errors detected since the last time the
buffer was erased. The buffer is written from left to right. When an error
occurs that is not yet in the error code buffer, it is displayed at the left
side and all other errors shift one position to the right.
An error will be added to the buffer if this error differs from any error in
the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a deadlock situation. It
must always be diagnosable (e.g. error buffer via OSD or blinking LED).
In case a failure identified by an error code automatically results in other
error codes (cause and effect), only the error code of the MAIN failure is
displayed.
How to Read the Error
Buffer
You
can read the error buffer in following ways:
• On screen via the SAM/CSM (if you have a picture).
Example:
– ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the last and only
detected error
– ERROR: 034 013 000 000 000: Error code 13 was detected first and error
code 34 is the last detected (newest) error
• Via the blinking LED procedure (when you have no picture).
Error codes overview
In
this chassis only “layer 2” error codes are available and point to problems on
the SSB. They are triggered by LED blinking when CSM is activated. Only the
following layer 2 errors are defined:
How to Clear the Error
Buffer
The
error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu
• By using the CLEAR command in the Factory mode:
• By using the following
key sequence on the remote control transmitter: “062599” directly
followed by the OK button.
• If the contents of the error buffer have not changed for 50 hours, the error
buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the television
set, the error buffer is not reset.
Panel Code
Press
the following key sequence on a standard RC transmitter: “062598” directly
followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel
type: see column “Display Code” in below tab. After resetting the Display Code,
restart the set immediately.
