Philips 40PFG5100-77 LED LCD Service Modes, Error Codes, and Fault Finding - Chassis TPM15.4L
Philips 32PFG5100, Philips 40PFG5100 and Philips 48PFG5100 LED LCD TVs- how to enter service mode, adjustments, software update and more...The Service Mode feature is split into five parts:
* Service Alignment Mode (SAM).
* Factory Mode.
* Customer Service Mode (CSM).
* Computer Aided Repair Mode (ComPair).
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.
ComPair
Mode is used for communication between a computer and a TV on I2C /UART level
and can be used by a Service engineer to quickly diagnose the TV set by reading
out error codes, read and write in NVMs, communicate with ICs and the micro
processor (PWM, registers, etc.), and by making use of a fault finding
database. It will also be possible to up and download the software of the TV
set via I2C with help of ComPair. To do this, ComPair has to be connected to
the TV set via the ComPair connector, which will be accessible through the rear
of the set (without removing the rear cover).
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)

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: TPM142L.
* B is the region indication: E = Europe, A = AP/China, U = NAFTA, L = LATAM.
* XXX is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 0- 255.
* YYY is the sub version number: this is updated with a minor change of specification (incompatible with the previous versions). Numbering will go from 0- 255.
* MMM is the number of the mandatory (upgrade) release in association with the area of the mandatory (upgrade) release. Numbering will go from 0 - 255.
* TTT bit 7 to 1 is the area of the mandatory (upgrade) release where 0 - none, 1 - Netflix, rest reserved.
* TTT bit 0 : 0 = development release, 1 = production release.

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 center 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 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.
How
to Read the Error Buffer
You can read the error buffer in three 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).
> 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.
The
Blinking LED Procedure
Introduction
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.

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.

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.

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.

No Picture
When you have no picture, first make sure you have entered the correct display code.
Unstable Picture via HDMI input
Check (via ComPair or factory mode) if HDMI EDID data is properly programmed
No Picture via HDMI input
Check if HDCP key is valid. This can be done in CSM.
TV Will Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.
Audio Amplifier
The Class
D-IC U601 has a powerpad 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.
CSM
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.
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.
Display
option code
Attention: In case the SSB is replaced, always check the Panel Code in CSM, even when picture is available. Performance with the incorrect display option code can lead to unwanted side-effects for certain conditions.

To store the data:
> Press OK on the RC before the cursor is moved to the left.
> Select “Store” and press OK on the RC.
> Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a video generator to the RF input:
> EU/AP-PAL models: a PAL B/G TV-signal with a signal strength of at least 1 mV and a frequency of 475.25 MHz
> US/AP-NTSC models: an NTSC M/N TV-signal with a signal strength of at least 1 mV and a frequency of 61.25 MHz (channel 3).
> LATAM models: an NTSC M TV-signal with a signal strength of at least 1 mV and a frequency of 61.25 MHz (channel 3).
RGB Alignment
White Tone Alignment:
> Activate SAM.
> Select “RGB Align.” and choose a color temperature.
> Use a 100% white screen as input signal and set the following values:
* “Red BL Offset” and “Green BL Offset” to “7” (if present).
* All “White point” values initial to “128”
In case you have a colour analyser:
> Measure with a calibrated (phosphor- independent) color analyser (e.g. Minolta CA-210) in the center of the screen.
Consequently, the measurement needs to be done in a dark environment.
> Adjust the correct x, y coordinates (while holding one of the White
point registers R, G or B on max. value) by means of decreasing the
value of one or two other white points to the correct x, y coordinates
Tolerance: dx: ± 0.003, dy: ± 0.003.
> Repeat this step for the other colour Temperatures that need to be aligned.
> When finished return to the SAM root menu and press STANDBY on the RC to store the aligned values to the NVM.
If you do not have a color analyser, you can use the default values.
This is the next best solution. The default values are average values
coming from production (statistics).

> Enter SAM mode.
> Select a colour temperature (e.g. COOL, NORMAL, or WARM).
> Set the RED, GREEN and BLUE default values according to the values in back to div.table below
> When finished press OK on the RC, then press STORE to store the aligned values to the NVM.
> Restore the initial picture settings after the alignments.
> Enter SAM mode.
> Select a colour temperature (e.g. COOL, NORMAL, or WARM).
> Set the RED, GREEN and BLUE default values according to the values in back to div.table below
> When finished press OK on the RC, then press STORE to store the aligned values to the NVM.
> Restore the initial picture settings after the alignments.
This
group setting of color temperature will be applied automatically to the TV /
VGA / HDMI / AV sources.

Introduction
The microprocessor communicates with a large number of I2C ICs in the set. To ensure good communication and to make digital diagnosis possible, the microprocessor has to know which ICs to address. The presence / absence of these MT5580 ICs is made known by the option codes.
Notes:
* After changing the option(s), save them by pressing the OK button on the RC before the cursor is moved to the left, select STORE and press OK on the RC.

Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB. A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the ComPair tool or use the “NVM editor” and “Dealer options” items in SAM (do not forget to “store”).
After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM. The loading of the CTN and production code can also be done via compare (Model number programming).
In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
Remark:
* After the NVM has been replaced, go to SAM and scroll to the
<Reload MAC address>
* Select the item and press <OK> on the RC.
