Precautions, Notes, and Abbreviation List

3. Precautions, Notes, and Abbreviation List

Index of this chapter:

3.1 Safety Instructions

3.2 Warnings

3.3 Notes

3.4 Abbreviation List

3.1 Safety Instructions

Safety regulations require the following during a repair:

• Connect the set to the Mains/AC Power via an isolation transformer (> 800 VA).

• Replace safety components, indicated by the symbol h, only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points:

• Route the wire trees correctly and fix them with the mounted cable clamps.

• Check the insulation of the Mains/AC Power lead for external damage.

• Check the strain relief of the Mains/AC Power cord for proper function.

• Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply):

1. Unplug the Mains/AC Power cord and connect a wire

between the two pins of the Mains/AC Power plug.

2. Set the Mains/AC Power switch to the “on” position

(keep the Mains/AC Power cord unplugged!).

3. Measure the resistance value between the pins of the

Mains/AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 M and 12 M.

4. Switch “off” the set, and remove the wire between the

two pins of the Mains/AC Power plug.

• Check the cabinet for defects, to prevent touching of any inner parts by the customer.

3.2 Warnings

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD w). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential.

• Be careful during measurements in the high voltage section.

• Never replace modules or other components while the unit is switched “on”.

• When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

3.3 Notes

3.3.1 General

• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3).

• Where necessary, measure the waveforms and voltages with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.

3.3.2 Schematic Notes

• All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 k).

• Resistor values with no multiplier may be indicated with either an “E” or an “R” (e.g. 220E or 220R indicates 220 ).

• All capacitor values are given in micro-farads (10 nano-farads (n 10

• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).

• An “asterisk” (*) indicates component usage varies. Refer to the diversity tables for the correct values.

• The correct component values are listed on the Philips Spare Parts Web Portal.

3.3.3 Spare Parts

For the latest spare part overview, consult your Philips Spare Part web portal.

3.3.4 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this URL: http://www.atyourservice-magazine.com “Magazine”, then go to “Repair downloads”. Here you will find Information on how to deal with BGA-ICs.

BGA Temperature Profiles

For BGA-ICs, you must use the correct temperature-profile. Where applicable and available, this profile is added to the IC Data Sheet information section in this manual.

3.3.5 Lead-free Soldering

Due to lead-free technology some rules have to be respected by the workshop during a repair:

• Use only lead-free soldering tin. If lead-free solder paste is required, please contact the manufacturer of your soldering equipment. In general, use of solder paste within workshops should be avoided because paste is not easy to store and to handle.

• Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able: – To reach a solder-tip temperature of at least 400°C. – To stabilize the adjusted temperature at the solder-tip. – To exchange solder-tips for different applications.

• Adjust your solder tool so that a temperature of around 360°C - 380°C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch “off” unused equipment or reduce heat.

• Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

3.3.6 Alternative BOM identification

It should be noted that on the European Service website, “Alternative BOM” is referred to as “Design variant”.

The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then

Precautions, Notes, and Abbreviation List

result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number. By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial number contains the number “1” (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts! For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number.

Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. SN is Lysomice, RJ is Kobierzyce), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in example below it is 2010 week 10 / 2010 week 17). The 6 last digits contain the serial number.

Figure 3-1 Serial number (example)

3.3.7 Board Level Repair (BLR) or Component Level Repair (CLR)

If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level. If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging!

3.3.8 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.

While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

• Always respect voltages. While some may not be

dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

For easy servicing of a TV set, the set should be put face down on a soft flat surface, foam buffers or other specific workshop tools. Ensure that a stable situation is created to perform measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.

5.1 Test Points

In the chassis schematics and layout overviews, the test points are mentioned. In the schematics and layouts, test points are indicated with “Fxxx” or “Ixxx”. As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. Several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective.

Perform measurements under the following conditions:

• Service Default Mode.

• Video: Color bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

The Service Mode feature is split into four parts:

• Service Default Mode (SDM).

• Service Alignment Mode (SAM).

• Customer Service Mode (CSM).

• Computer Aided Repair Mode (ComPair).

SDM and SAM offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:

• A pre-defined situation to ensure measurements can be

made under uniform conditions (SDM).

• Activates the blinking LED procedure for error identification

when no picture is available (SDM).

• The possibility to overrule software protections when SDM

is entered via the Service pins.

• Make alignments (e.g. White Tone), (de)select options,

enter options codes, reset the error buffer (SAM).

• Display information (“SDM” or “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 uP (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).

In this chassis, the set has to be put in Service Mode (SDM, SDA) before you can use ComPair.

2012-Apr-20

5.2.1 General

Next 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 SDM and 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 SDM, SAM, and CSM. The screen will show: “AAAAAAB-XX.YY”, where:

• AAAAAA is the chassis name: L12M11L.

• B is the region indication: E= Europe, A= AP/China, U= NAFTA, L= LATAM.

• XX is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 01 - 99 and AA ZZ. – If the main version number changes, the new version

number is written in the NVM.

– If the main version number changes, the default

settings are loaded.

• YY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions) Numbering will go from 00 - 99. – If the sub version number changes, the new version

number is written in the NVM.

– If the NVM is fresh, the software identification, version,

and cluster will be written to NVM.

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/HOME and “xxx

”, where “xxx” is a 3 digit decimal va see sticker on the side/bottom of t is accepted and stored in NVM, the set will switch to Stand-by, to indicate that the process has been completed.

Figure 5-1 Location of Display Option Code sticker

During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSBrelated (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, he needs to look to the side/bottom sticker to identify the set, for further actions.

SDM

EN 21L12M1.1L LA 5.

5.2.2 Service Default Mode (SDM)

Purpose

Set the TV in SDM mode in order to be able to create a predefined setting for measurements to be made. In this platform, a simplified SDM is introduced (without protection override and without tuning to a predefined frequency).

Specifications

• Set linear video and audio settings to 50%, but volume to 25%. Stored user settings are not affected.

• Set Smart Picture to “Game”.

• Set Smart Sound to “Standard”.

• Tune channel to:

- for analogue SDM: channel 3 (61.25 MHz)

- for digital SDM: channel 26 (545.143 MHz).

• For digital SDM: set PID default from the stream.

• All service-unfriendly modes (if present) are disabled, since they interfere with diagnosing/repairing a set. These service unfriendly modes are: – (Sleep) timer. – Blue mute/Wall paper. – Auto switch “off” (when there is no “ident” signal). – Hotel or hospital mode. – Child lock or parental lock (manual or via V-chip). – Skipping, blanking of “Not favorite”, “Skipped” or

“Locked” presets/channels.

– Automatic storing of Personal Preset or Last Status

settings.

– Automatic user menu time-out (menu switches back/

OFF automatically.

– Auto Volume levelling (AVL).

How to Activate

To activate analogue SDM, use one of the following methods:

• Press the following key sequence on the RC transmitter: “062596” directly followed by the MENU button.

• Short one of the “Service” pads on the TV board during cold start (see Figure 5-2 (remove the short after start-up). Caution: When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.

To activate digital SDM:

• Press the following sequence on the RC transmitter: “062593” directly followed by the MENU button.

). Then press the mains button

• AAAAAAB-XX.YY: See paragraph Software

Identification, Version, and Cluster for the SW name

definition.

• ERR: Shows all errors detected since the last time the buffer was erased in format <xxx> <xxx> <xxx> <xxx> <xxx> (five errors possible).

• OP: Used to read-out the option bytes. Ten codes (in two rows) are possible.

How to Navigate

As this mode is read only, there is not much to navigate. To switch to other modes, use one of the following methods:

• Command MENU from the user remote will enter the normal user menu (brightness, contrast, color, etc...) with “SDM” OSD remaining, and pressing MENU key again will return to the last status of SDM again.

• To prevent the OSD from interfering with measurements in SDM, command “OSD” or “i+” (“STATUS” or “INFO” for NAFTA and LATAM) from the user remote will toggle the OSD “on/off” with “SDM” OSD remaining always “on”.

• Press the following key sequence on the remote control transmitter: “062596” directly followed by the INFO[i+]/OK button to switch to SAM (do not allow the display to time out between entries while keying the sequence).

How to Exit

Switch the set to Stand-by.

• pressing the standby button on the remote control transmitter or on the television set, or

• via a standard RC-transmitter by keying the “00” sequence.

If you switch the television set “off” by removing the mains (i.e., unplugging the television), the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared. The error buffer will only be cleared when the “clear” command is used in the SAM menu.

Note:

• If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared.

• In case the set is accidentally in Factory mode (with an “F” displayed on the screen), pressing and holding “VOL-“ button for 5 seconds and then followed by pressing and holding the “CH-” button for another 5 seconds should exit the Factory mode.

5.2.4 Customer Service Mode (CSM)

Purpose

The Customer Service Mode shows error codes and information on the TV’s operation settings. A call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps them to diagnose problems and failures in the TV before making a service call. The CSM is a read-only mode; therefore, modifications are not possible in this mode.

Specifications

• Ignore “Service unfriendly modes”.

• Set volume to 25%.

• Set Smart Picture to “Game”.

• Set Smart Sound to “Standard”.

• Line number for every line (to make CSM language independent).

• Set the screen mode to full screen (all contents on screen is visible).

• After leaving the Customer Service Mode, the original settings are restored.

• Possibility to use “CH+” or “CH-” for channel surfing, or enter the specific channel number on the RC.

5.3 Service Tools

5.3.1 ComPair

EN 23L12M1.1L LA 5.

Figure 5-3 ComPair II interface connection

Caution: It is compulsory to connect the TV to the PC as

shown in the picture above (with the ComPair interface in between), as the ComPair interface acts as a level shifter. If one connects the TV directly to the PC (via UART), ICs will be blown!

How to Order

ComPair II order codes:

• ComPair II interface: 3122 785 91020.

• ComPair UART interface cable: 3138 188 75051.

• Program software can be downloaded from the Philips Service web portal.

Note: For this chassis, “Pgammar” and “T-con NVM” programming (VCOM alignment) are added to ComPair.

Prerequisite

In this chassis, ComPair can only be used in one of the Service Modes (SAM, SDM).

Introduction

ComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics products. and offers the following:

1. ComPair helps you to quickly get an understanding on how to repair the chassis in a short and effective way.

2. ComPair allows very detailed diagnostics and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C or UART commands yourself, because ComPair takes care of this.

3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the uP is working) and all repair information is directly available.

4. ComPair features TV software up possibilities.

Specifications

ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The (new) ComPair II interface box is connected to the PC via an USB cable. For the TV chassis, the ComPair interface box and the TV communicate via a bi-directional cable via the service connector(s).

How to Connect

This is described in the ComPair chassis fault finding database.

Additional cables for VCOM Alignment

•ComPair/I

C interface cable: 3122 785 90004.

• ComPair/VGA adapter cable: 9965 100 09269.

5.4 Error Codes

5.4.1 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 I

• General I 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.

Service Modes, Error Codes, and Fault Finding

5.4.2 How to Read the Error Buffer

You can read the error buffer in three ways:

• On screen via the SAM/SDM/CSM (if you have a picture). Example: – ERROR: 0 0 0 0 0 : No errors detected – ERROR: 6 0 0 0 0 : Error code 6 is the last and only

detected error

– ERROR: 9 6 0 0 0 : Error code 6 was detected first and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no picture). See paragraph 5.5 The Blinking LED Procedure

•Via ComPair.

5.4.3 Error codes

The “layer 1” error codes are pointing to the defective board. They are triggered by LED blinking when CSM is activated. In the LC10 platform, only two boards are present: the SSB and the PSU/IPB, meaning only the following layer 1 errors are defined:

• 2: SSB

• 3: IPB/PSU

•4: Display

Table 5-1 Error code table

Defective board

Layer-2 error code Defective device

5.4.4 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 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.

5.5 The Blinking LED Procedure

5.5.1 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.

Example (2): the content of the error buffer is “129600” 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.

5.5.2 Displaying the Entire Error Buffer

Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered.

5.6 Fault Finding and Repair Tips

Notes:

• 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.

5.6.1 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.

5.6.2 Load Default NVM Values

It is possible to download default values automatically into the NVM in case a blank NVM is placed or when the NVM first 20 address contents are “FF”. After the default values are downloaded, it is possible to start-up and to start aligning the TV set. To initiate a forced default download the following action has to be performed:

1. Switch “off” the TV set with the mains cord disconnected from the wall outlet (it does not matter if this is from “Standby” or “Off” situation).

2. Short-circuit the SDM pads on the SSB (keep short circuited, see Figure 5-2

3. Press “P+” or “CH+” on the local keyboard (and keep it pressed).

4. Reconnect the mains supply to the wall outlet.

5. Release the “P+” or “CH+” when the set is started up and has entered SDM.

When the downloading has completed successfully, the set will perform a restart. After this, put the set to Stand-by and remove the short-circuit on the SDM pads.

Alternative method:

It is also 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.

5.6.3 No Picture

When you have no picture, first make sure you have entered the correct display code. See Display Option Code Selection

for the instructions.

Check if HDCP key is valid. This can be done in CSM.

5.6.6 HDMI CEC Not Functioning

Go to Home/Menu ->Setup -> Installation -> Preference and set the Easylink option to “on”. Also check if the connected device is CEC enabled.

5.6.7 TV Will Not Start-up from Stand-by.

Possible Stand-by Controller failure. Reflash the SW.

5.6.8 Cannot measure 1 kHz signal at tweeter 1D01 connector

This is normal behavior. Sound system is active 2.1 system with separate tweeter and subwoofer paths. Use 8 kHz test signal for tweeter measurement.

5.6.9 Low output measured at tweeter 1D01 connector

This is normal behavior. Tweeter only covers higher frequency for rated power (4 W each), whereas the subwoofer output (1D02 connector) is full range coverage for output power of 12 W.

5.6.10 No sound output at class D amplifier

Check following points:

• Presence of both supply +V

S input signal: pins 15, 20, 21, 22

•I

(12 V) & 3V3D (3.3 V)

SND

- pin 15: MCLK = 12.288 MHz

- pin 20: LRCLK = 48 kHz

- pin 21: SCLK = 3.072 MHz

- pin 22: SDIN = audio data.

• Check I

C communication: pins 23 and 24

• Check startup GPIO: pins 19 and 25; for normal operation, both should be HIGH

• Check outputs: pins 1, 36, 39 and 46; all should have a 12 V PWM signal with a switching frequency of 384 kHz.

5.6.11 Front-end: no picture in analog RF mode

Check following points:

• Tuner supply voltage (3V3) presence available at pin 2/4 7216 and F203

C lines are working correctly (3V3)

•I

• Manually store a known channel and check if there is IF output at tuner pins 7 & 8; if not, tuner may be faulty

• Check whether picture is present in CVBS; in not, check Video section.

5.6.12 Front-end: no picture in digital RF mode

Check following points:

• Tuner supply voltage (3V3) presence available at pin 2/4 7216 and F203

C lines are working correctly (3V3)

•I

• Manually store a known channel and check if there is IF output at tuner pins 2& 3; if not, tuner may be faulty

• Supply voltage (1V2, 2V5, 3V3) presence available to digital demodulator 7210

• Correct functioning of crystal 1205 (41 MHz)

• Pin DEMOD_RST is HIGH in normal operation

• Transport stream output from 7210 is available; if yes, check Video section.

5.6.13 USB troubleshooting

• USB hub does not work when it is plugged in to USB2 and

-3.

-> Connect USB hub to USB1 (only this port supports hub)

• TV cannot detect the presence of USB devices.

-> USB device maybe faulty, replace with another USB device.

• TV cannot detect the presence of USB devices.

-> Ensure USB device connected to the TV USB input ports comply with USB standard (USB certified).

• TV sometimes can/cannot detect USB devices.

-> If connected to a passive USB hub, remove the passive USB hub.

-> Devices connected to a passive USB hub may have drawn current exceeding 500 mA (= limit from TV USB port).

5.6.14 Ethernet troubleshooting

• Ethernet cannot establish link.

-> Check the ethernet magnetic that it is stuffed with the correct orientation.

• When connected to computer, the speed indicated on the computer screen is 10 Mbps instead of 100 Mbps.

-> Check the computer network properties setting and ensure that it is set to “Auto”.

• Unable to login to NetTV website.

-> Make sure all of the keys are loaded in e.g. MAC address, ECD key, etc.

5.6.15 HDMI troubleshooting

• TV cannot detect the presence of HDMI source.

-> Check if there is +5 V at pin 18 of HDMI connector.

• No picture on TV screen.

-> Make sure HDCP is valid.

• In PC mode, TV is unable to display picture for certain output resolutions.

-> Check TV specification if the TV can support the selected resolution.

• CEC not functioning.

-> Turn on “Easyliok” feature from the TV menu.

5.7 Software Upgrading

5.7.1 Introduction

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.

5.7.2 Main Software Upgrade

Automatic Software Upgrade

In “normal” conditions, so when there is no major problem with the TV, the main software and the default software upgrade application can be upgraded with the “autorun.upg” (FUS part in the one-zip file). This can also be done by the consumers themselves, but they will have to get their software from the commercial Philips website or via the Software Update Assistant in the user menu (see DFU). The “autorun.upg” file must be placed in the root of your USB stick.

How to upgrade:

1. Copy the “autorun.upg” file to the root of an USB stick.

2. Insert the USB stick in the side I/O while the set is “on”. The TV will prompt an upgrade message. Press “Update” to continue, after which the upgrading process will start. As
