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...

Service Modes
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.

Service Alignment Mode (SAM)
> To modify the NVM.
> To display/clear the error code buffer.
> To perform alignments.
Specifications
* Operation hours counter (maximum five digits displayed).
* Software version, error codes, and option settings display.
* Error buffer clearing.

How to 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

Software Upgrading
Description
It is possible for the user to upgrade the main software via the USB port. This allows replacement of a software image in a stand alone set. A description on how to upgrade the main software can be found in the DFU or on the Philips website.
Introduction
Philips continuously tries to improve its products, and it’s recommend that the TV software is updated when updates are available. Software update files can be obtained from the dealer or can be downloaded from the Philips  websites.

Preparing a portable memory for software upgrade
The following requirements have to be met:
1. A personal computer connected to the internet.
2. An archive utility that supports the ZIP-format (e.g. WinZip for Windows or Stufflt for Mac OS).
3. A FAT formatted USB memory stick (preferably empty).
Note:
1. Only FAT/DOS-formatted memory sticks are supported.
2. Only use software update files that can be found on the Philips website.

Check the current TV software version

Before starting the software upgrade procedure, it is advised to check that what the current TV software:

1. Press the “1 2 3 6 5 4” button on the remote control to enter the CSM mode.

2. Use the up/down cursor keys to select “Current Main Software”.

If the current software version of the TV is the same as the latest update file found on philips.com/support, it is not necessary to update the TV software.

Download the latest software

1. Open the internet page philips.com/support.

2. Find information and software related to the TV.

3. Select the latest software update file and download it to the PC.

4. Insert the USB memory stick into one of the USB ports of the PC.

5. Decompress the downloaded ZIP file and copy it to the root directory to Update the TV software

1. Turn the TV on and wait for it to boot completely.

2. Insert the USB memory stick that contains the software update files in one of the TV’s USB ports.

3. The TV will detect the USB memory stick automatically.

Then a window jumps out.

Note: If the USB flash drive is not detected after power up, disconnect it and re-insert it.

4. Select [Update] and press OK.

5. To proceed, In next menu select [Start] and press OK to start software updates.

6. Upgrading will now begins and the status of the updating progress will be displayed.

7. When the TV software is updated. Remove your USB flash drive, then select [Restart] and press OK to restart the TV. f the USB flash drive.

Note:
* Do not remove the USB flash drive during the software update.
* If a power failure occurs during the update, do not remove the USB flash drive from the TV. The TV will continue the software update as soon as the power comes up again.
* If an error occurs during the update retry the procedure or contact the dealer.
* We do not recommend downgrading to an older version.
* Once the upgrade is finished, use the PC to remove the TV software from the USB portable memory.

Content and Usage of the One-Zip Software File Below you find a content explanation of the One-Zip file, and instructions on how and when to use it. Only files that are relevant for Service are mentioned here.
> EDID_clustername.zip: Contains the EDID content of the different EDID NVMs. See ComPair for further instructions.

> FUS_clustername_version.zip: Contains the file downloaded which is needed to upgrade the TV main software and the software download application.
> NVM_clustername_version.zip: Default NVM content.
Must be programmed via ComPair.

How to Copy NVM Data to/from USB
When copying data to and from a USB memory stick, the folder “repair” is used. When inserting an empty USB memory stick, and downloading data to the stick, the TV will create this folder.  When sending data from a USB memory stick to a TV, the intended data must be available in the “repair” folder.
Note that when copying EDID data to the TV, all necessary EDID files must be in this folder.

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).

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.

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.

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.

General Alignment Conditions
Perform all electrical adjustments under the following conditions:
* Power supply voltage: 90 - 264 VAC, 50/ 60 ± 3 Hz.
* Connect the set to the mains via an isolation transformer with low internal resistance.
* Allow the set to warm up for approximately 15 minutes.
* Measure voltages and waveforms in relation to correct ground (e.g. measure audio signals in relation to AUDIO_GND).
Caution: It is not allowed to use heat sinks as ground.
* Test probe: Ri > 10 MW, Ci < 20 pF.
* Use an isolated trimmer/screwdriver to perform alignments.

Hardware Alignments: Not applicable.

Software Alignments

Put the set in SAM mode (see Chapter 5. Service Modes, Error Codes, and Fault Finding). The SAM menu will now appear on the screen. Select RGB Align and go to one of the sub menus.

The alignments are explained below.

The following items can be aligned:

> White point.

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).

Display Adjustment

You can use the default values. The default values are average values coming from production.
> 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.

Option Settings
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.

* The new option setting is only active after the TV is switched “off” / “stand-by” and “on” again with the mains switch (the NVM is then read again).

Option Code Overview
Enter SAM mode to check the option codes. they could be edited in the NVM.
Display Code Overview
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 the table below. After resetting the Display Code, restart the set immediately.

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.

Reset of Repaired SSB
Instruction
After NVM replacement, reload MAC address via SAM menu.This ensures the correct MAC address to be available in CSM for future repair actions.
Way of working:
* 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.
Notes:
* Only applicable to all related models that are “Smart TV level 0”enabled (only YouTube access). For models without internet connection feature, no action is needed.
* HDCP keys are located in the NVM. If you are loading NVM with the ComPair tool, there is warning message displayed.  New NVM EEPROMs are shipped with pre-loaded HDCP keys.

SSB Identification

SSB’s of this chassis are identified by a “715” code on the SSB.

715Axxxx-Nnn-MMM-oooo

* 715 main category, Printed Wiring Board

* Axxxx sub category, sequential coding number

* Nnn Version code

* N Development number

* nn Production number

* MMM Mounting variation code

* oooo Optional variation code

Make sure when replacing an SSB the SSB identification codes match the replacement panel.
