Service
Modes
The
Service Mode feature is split into four parts:
• Service Alignment Mode (SAM).
• Factory Mode.
• Customer Service Mode (CSM).
SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:
• Make alignments (e.g. White Tone), reset the error buffer
SAM and Factory Mode.
• Display information (“SAM” indication in upper right corner of screen, error buffer, software version, operating hours, options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the consumer. The CSM displays diagnosis information, which the customer can forward to the dealer or call centre. In CSM mode, “CSM”, is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
• Increase the home repair hit rate.
• Decrease the number of nuisance calls.
• Solved customers’ problem without home visit.
Note: For the new model range, a new remote control (RC) is used with some renamed buttons. This has an impact on the activation of the Service modes. For instance the old “MENU” button is now called “HOME” (or is indicated by a “house” icon).
• Factory Mode.
• Customer Service Mode (CSM).

items are applicable to all Service Modes or are general.
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.
Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main menu display of SAM and CSM.
The screen will show: “AAAAAAB-XXX.YYY.MMM.TTT”,
where:
• AAAAAA is the chassis name: TPM165L.
• B is the region indication: E = Europe, A = AP/China, U =
NAFTA, L = LATAM.

Display
Option Code Selection
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: “062598” 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.

Error
Codes
Introduction
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
• 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: 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
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.

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 SAM, 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.
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 SAM, 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.

How
to Activate Blinking LED Procedure
Use one of the following methods:
• Activate CSM.The blinking front LED will show the layer 1 error(s), this works in “normal operation” mode or automatically when the error/protection is monitored by the standby processor.
In case no picture is shown and there is no LED blinking, read the logging to detect whether “error devices” are mentioned.

Fault
Finding and Repair Tips
Note:
• It is assumed that the components are mounted correctly with correct values and no bad solder joints.
• Before any fault finding actions, check if the correct options are set.

NVM
Editor
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.
Caution:
• 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

Amplifier
The Class D-IC U601 has a powerpad for cooling. When the IC is replaced it must be ensured that the powerpad 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.

Loudspeakers
Make sure that the volume is set to minimum during disconnecting the speakers in the ON-state of the TV. The audio amplifier can be damaged by disconnecting the speakers during ON-state of the set.
