When after an SSB or display exchange, the display option code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after such a repair.
To do so, press the following key sequence on a standard RC transmitter: “062596” directly followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel type.
When the value is accepted and stored in NVM, the set will switch to Stand-by, to indicate that the process has been completed. During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSB related (e.g. Model and Prod. S/N). Therefore, “Model” and “Prod. S/N” data is changed into “See Type Plate”. In case a call centre or consumer reads “See Type Plate” in CSM mode.
Life
Timer
During the life time cycle of the TV set, a timer is kept (called “Op. Hour”). It counts the normal operation hours (not the Stand-by hours). The actual value of the timer is displayed in SAM in a decimal value. Every two soft-resets increase the hour by + 1. Stand-by hours are not counted.

Error
Codes
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 or via ComPair).
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.

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.
To
Read the Error Buffer
On
screen via the SAM/SDM/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.
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)
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.
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.
• 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.
The
Blinking LED Procedure
The
software is capable of identifying different kinds of errors.Because it is
possible that more than one error can occur over time, an error buffer is
available, which is capable of storing the last five errors that occurred. This
is useful if the OSD is not working properly.
Errors can also be displayed by the blinking LED procedure.The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated.
Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.

Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.
•
1 long blink of 5 seconds to start the sequence.
• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks.

Editor• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks.
In
some cases, it can be convenient if one directly can change the NVM contents.
This can be done with the “NVM Editor” in SAM mode. With this option, single
bytes can be changed.
Do
not change these, without understanding the function of each setting, because
incorrect NVM settings may seriously hamper the correct functioning of the TV
set!
• Always write down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect.

Load
Default NVM Values
It
is possible to upload the default values to the NVM with ComPair in case the SW
is changed, the NVM is replaced with a new (empty) one, or when the NVM content
is corrupted.
After replacing an EEPROM (or with a defective/no EEPROM), default settings should be used to enable the set to start-up and allow the Service Default Mode and Service Alignment Mode to be accessed.

The Class D-IC U602 has a power pad for cooling. When the IC is replaced it must be ensured that the power pad is very well pushed to the PWB while the solder is still liquid. This is needed to insure that the cooling is guaranteed; otherwise the Class D-IC could break down in short time.

When CSM is activated and there is a USB memory stick connected to the TV, the software will dump the complete CSM content to the USB memory stick. The file (Csm.txt) will be saved in the root of the USB memory stick.
