Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

Index of this chapter:

2.1 Safety Instructions

2.2 Maintenance Instructions

2.3 Warnings

2.4 Notes

2.1 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.

• Wear safety goggles when you replace the CRT.

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

• General repair instruction: as a strict precaution, we advise you to re-solder the solder connections through which the horizontal deflection current flows. In particular this is valid for the:

1. Pins of the line output transformer (LOT).

2. Fly-back capacitor(s).

3. S-correction capacitor(s).

4. Line output transistor.

5. Pins of the connector with wires to the deflection coil.

6. Other components through which the deflection current

flows. Note: This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections, and is therefore only necessary for television sets more than two years old.

• Route the wire trees and EHT cable correctly and secure

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, to prevent the cord from touching the CRT, hot components, or heat sinks.

• 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 Mohm and 12 Mohm.

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.

2.2 Maintenance Instructions

We recommend a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:

• When a customer uses the set under normal circumstances, for example in a living room, the recommended interval is three to five years.

• When a customer uses the set in an environment with higher dust, grease, or moisture levels, for example in a kitchen, the recommended interval is one year.

• The maintenance inspection includes the following actions:

1. Perform the “general repair instruction” noted above.

2. Clean the power supply and deflection circuitry on the chassis.

3. Clean the picture tube panel and the neck of the picture tube.

2.3 Warnings

• In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in figure “Discharge picture tube”, to discharge the picture tube. Use a high voltage probe and a multi-meter (position V until the meter reading is 0 V (after approx. 30 s).

V

Figure 2-1 Discharge picture tube

• 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. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and earth cable) 4822 310 10671.

– Wristband tester 4822 344 13999.

• 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 prevents circuits from becoming unstable.

2.4 Notes

2.4.1 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 (see chapter 5) 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.

• The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

• The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.4.3 Rework on BGA (Ball Grid Array) ICs

General

Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded.

Device Removal

As is the case with any component that is being removed, it is essential when removing an (LF)BGA, that the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the risk of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet.

Area Preparation

When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has been shown to result in problems during re-soldering.

Device Replacement

The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times.

More Information

For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select “Magazine”, then go to “Workshop Information”. Here you will find Information on how to deal with BGA-ICs.

Figure 2-3 Lead-free logo

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

• Use only lead-free soldering tin Philips SAC305 with order code 0622 149 00106. 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 stabilise 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 stabilised 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 clean the solder-joint from old tin and re-solder with new tin.

• Use only original spare-parts listed in the Service-Manuals. Not listed standard material (commodities) has to be purchased at external companies.

• Special information for lead-free BGA ICs: these ICs will be delivered in so-called "dry-packaging" to protect the IC against moisture. This packaging may only be opened shortly before it is used (soldered). Otherwise the body of the IC gets "wet" inside and during the heating time the structure of the IC will be destroyed due to high (steam-) pressure inside the body. If the packaging was opened before usage, the IC has to be heated up for some hours (around 90°C) for drying (think of ESD-protection!).

Do not re-use BGAs at all!

EN 6 ES1E2.

• For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes.

In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method:

• Always use the highest temperature to solder, when using SAC305 (see also instructions below).

• De-solder thoroughly (clean solder joints to avoid the mixing of two alloys).

Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions). You will find this and more technical information within the "Magazine", chapter "Workshop information". For additional questions please contact your local repair help desk.

2.4.5 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.

Note: Figures below can deviate slightly from the actual situation, due to the different set executions.

4.1 Service Connector (for ComPair)

For service diagnostics with ComPair, it is not necessary to disassemble the set. You only have to connect the ComPair interface box, via the appropriate cable, to the service connector (on the rear of the set, see figure 1-2), and start the program (see also chapter 5 "Service Modes, Error Codes, and Fault Finding ").

4.2 Set Disassembly

Follow the disassemble instructions in described order.

4.2.1 Rear Cover Removal

Warning: disconnect the mains power cord before you remove

the rear cover.

1. Remove all the fixation screws of the rear cover.

2. Now the rear cover can be removed.

Solder Side LSP

To get access to the bottom side (solder side) of the LSP, do the following (see figure 4-1):

1. Remove the connector of the mains cable (coming from the mains switch-module) from the LSP.

2. Remove the cable (connector) from the side I/O panel.

3. Release some wiring from their fixation clamps, in order to get room for repositioning the LSP.

4. Flip the LSP 90 degrees clockwise [2], and place it in the fixation hole at the left side of the bottom tray [3].

5. Push the LSP forward to fix it. (Alternatively, the LSP may also be placed on your work bench without being positioned in its fixation hole, or it may even be removed from the bracket for better accessibility, see “Assy / Board Removal: Large Signal Panel (LSP)” on the next pages.)

4.3 Service Positions

This chassis has several predefined service positions, for better accessibility. They are explained below in more detail.

4.3.1 Large Signal Panel (LSP)

Component Side LSP

For better accessibility of the LSP, do the following (see Figure “Service position 1”):

1. Simultanuously do the following: a) pull the two plastic locking handles at the mid left and mid right side of the bracket gently backwards to unlock the bracket, and b) loosen the bracket from the bottom tray, by pulling it backwards. N.B.: You do not need to pull the other two locking handles backwards.

2. Remove the LSP-bracket from the bottom tray by lifting it upwards.

3. Hook the bracket in the first row of fixation holes of the bottom tray. In other words, reposition the bracket from [1] to [2].

CL 36532058_078.eps

Figure 4-2 Service position 2

4.3.2 Small Signal Board (SSB)

In fact, there is no predefined service position for the SSB. Most test points are located on the A-side (side that is facing the tuner). If you have to replace ICs, you must take the complete SSB module out of the SIMM-connector.

Notes:

• For better access to the SSB, it is possible to order an “extension tool” with cables. You can use this service extension tool to connect a Small Signal Board (SSB) of an ES1E, A02, A10, or EMG (EMx) chassis, via two “IDE” cables to the SIMM connector in the set. In this way, you can service the SSB more easily outside the TV set. You can order this tool under 12nc: 9965 000 14526.

• If necessary for the measurement, you can put the LSP in “service position 2” (as described above).

4.4 Assy / Board Removal

Sometimes, it can be necessary to swap a complete assy or Printed Wiring Board (PWB). How that can be done is explained below.

3. Disconnect the other cables (loudspeaker, mains, etc.) from the LSP, and release some cables from their fixation clamps.

4. Press the fixation clamp on the left front side of the LSPbracket (close to the white arrow/loudspeaker connector) to unlock the LSP, and tilt it upwards (the board hinges at the right side).

5. Remove the board from the bracket by unhooking it from its fixation clamps on the right side.

4.5 Set Re-assembly

To re-assemble the whole set, do all processes in reverse order. Be sure that, before the rear cover is mounted:

• The mains cord is postioned correctly in its guiding brackets (make sure that the strain relief will function correctly!).

• All wires/cables are returned in their original positions. This is very important, in view of the “hot” and “EHT” areas of the set.

5.1 Test Points

See chapter 6 " Block Diagrams, Testpoint Overview, and Waveforms".

Perform measurements under the following conditions:

• Service Default Mode.

• Video: colour bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

Service Default Mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Mode (CSM) is used for communication between a Philips Customer Care Centre (P3C) and a customer.

There is also the option of using ComPair, a hardware interface between a computer (see requirements below) and the TV chassis. It offers the ability of structured troubleshooting, test pattern generation, error code reading, software version readout, and software upgrading. Minimum requirements: a Pentium processor, Windows 95/ 98, and a CD-ROM drive (see also paragraph “ComPair”).

5.2.1 Service Default Mode (SDM)

Purpose

• To create a pre-defined setting for measurement purposes.

• To override SW protections (only when SDM is activated via shorting the SDM pins on the SSB).

• To start the blinking LED procedure.

• Inspection of error buffer, life timer, and software version.

Specifications

• Tuning frequency: 475.25 MHz for PAL/SECAM.

• Colour system: SECAM L for France or PAL B/G for the rest of Europe.

• All picture settings at 50 % (brightness, colour, contrast).

• All sound settings at 50 %, except volume at 25 %.

• All service-unfriendly modes (if present) are disabled, like: – (Sleep) timer. – Child/parental lock. –Blue mute. – Automatic volume limiter (AVL). – Auto switch-off (when no video signal was received for

10 minutes). – Skip/blank of non-favourite pre-sets. – Hotel or hospital mode. – Local keyboard block. – Smart modes. – Auto store of personal presets. – Auto user menu time-out.

How to Activate SDM

Use one of the following methods:

• Use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” button.

Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the “MENU” button again.

• Short circuit, during switch "on" of the set, the two solder pads on the SSB with the indication “FOR SERVICE”. These solder pads are located at the "tuner" side of the SSB (just above the large BGA IC). Caution: If the SDM is activated via these pins, all the software-controlled protections are de-activated for 15 s. When these 15 s are expired, the set will shutdown to protection mode.

• Use the DST-emulation feature of ComPair.

After activating this mode:

• “SDM” will appear in the upper right corner of the screen.

• Also, the error buffer, operating hours, and software version are displayed (can be toggled "on/off" with the "STATUS / OSD / [i+]" button).

• Blinking LED procedure will be started.

• All software-controlled protections are overridden for 15 s. When these 15 s are expired, the set will shutdown to protection mode.

Contents of SDM:

• HRS. Displays the accumulated total of operation hours (not the standby hours) in hexadecimal value.

• SW. Displays the date of the software and the software version of the ROM; example: A2EU04-5.10 = AAABBC-X.YY. – AAA= chassis name. – BB= region and/or function name: E= Europe, A= Asia

Pacific, U= NAFTA, L= LATAM, B= Basic, T= Top, P=

PAL, N= NTSC, S= Stereo, M= Mono. – C= the language cluster number. – X.Y= the software version, where X is the main version

number (different numbers are not compatible with one

another) and Y is the sub version number (a higher

number is always compatible with a lower number).

• ERR (followed by maximal 8 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph “Error Codes”).

How to Navigate

• When you press the “MENU” button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background).

• When you press the “STATUS / OSD / [i+]” button on the RC transmitter, the set will toggle between the full SDM screen or a screen with only the text "SDM" displayed on it. This mode is useful when performing measurements, then the OSD info will not generate interference.

How to Exit SDM

Use one of the following methods:

• Switch the set to STANDBY via a standard customer RCtransmitter (the error buffer is erased).

• Via a standard customer RC-transmitter: key in “00”sequence (the error buffer is not erased).

5.2.2 Service Alignment Mode (SAM)

Purpose

• To perform alignments.

• To change option settings.

• To easily identify the used software version.

How to Navigate

• In SAM, you can select the menu items with the “CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.

• With the “CURSOR LEFT/RIGHT” keys, it is possible to: – (De) activate the selected menu item. – Change the value of the selected menu item. – Activate the selected submenu.

• When you press the “MENU” button on the RC transmitter, the set will toggle between the SAM and the normal user menu (with the SAM mode still active in the background).

How to Exit SAM

Use one of the following methods:

• Switch the set to STANDBY via the RC-transmitter (the error buffer is erased).

• Via a standard customer RC-transmitter: key in “00”sequence (the error buffer is not erased).

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can call his dealer or the Philips helpdesk (P3C). The service technician can than ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode; therefore, modifications in this mode are not possible.

How to Activate CSM

Use one of the following methods:

• Press the “MUTE” button on the RC-transmitter simultaneously with any key on the TV for at least 4 seconds.

• Key in the code “123654” via the standard RC transmitter.

Notes:

• Activation of the CSM is only possible if there is no (user) menu on the screen!

• During CSM, sound volume is set to 25% of the scale, "Smart Sound" is set to "Theatre" mode, and "Smart Picture" is set to "Rich/Movies" mode temporarily to ensure a good picture and sound of the working set. After leaving CSM, the original settings are restored.

How to Navigate

By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, you can navigate through the menus.

5.3 Problems and Solving Tips (related to CSM)

Note: The problems described below are all related to the TV

settings. The procedures to change the value (or status) of the different settings are described above. New value(s) are automatically stored.

5.3.1 Picture Problems

Picture too Dark

1. Press SMART PICTURE on the RC. In case the picture improves, increase the “Brightness” or the “Contrast” value. The new value(s) are automatically stored (in “personal” pre-set) for all TV channels.

2. Check in CSM lines BRIGHTNESS and/or CONTRAST. If the value of line BRIGHTNESS is low (< 10) or the value of line CONTRAST is low (< 10), increase them.

Picture too Bright

1. Press SMART PICTURE on the RC. In case the picture improves, decrease the “Brightness” or the “Contrast” value. The new value(s) are automatically stored (in “personal” pre-set) for all TV channels.

2. Check in CSM lines BRIGHTNESS and/or CONTRAST. If the value of line BRIGHTNESS is high (> 50) or the value of line CONTRAST is high (> 50), decrease the “Brightness” or the “Contrast” value.

White Line Around Picture Elements and Text

1. Press SMART PICTURE on the RC. In case the picture improves, decrease the “Sharpness” value. The new value is automatically stored (in “personal” pre-set) for all TV channels.

2. Check in CSM line SHARPNESS. Decrease the “Sharpness” value. The new value is automatically stored for all TV channels.

No Picture

Check in CSM line 10 (SIGNAL). In case this line shows NO SIGNAL, check the aerial cable/aerial system.

Blue Picture

No proper signal is received. Check the aerial cable/aerial system.

Blue Picture and/or Unstable Picture

A scrambled or coded signal is received.

Black and White Picture

Check in CSM line COLOR. In case the value is low (< 10), increase the “Color” value. The new value is automatically stored for all TV channels.

No Colours/colour Lines around Picture Elements or Colours not Correct or Unstable Picture

1. Check in CSM line SYSTEM. If a “strange” system pops up, something has gone wrong during installation. Re-install the channel.

2. In case line SYSTEM is “FRANCE”, the installed system for this pre-set is SECAM, while PAL is required. Install the required program again: open the installation menu and perform manual installation. Select system “West Europe”.

Menu Text not Sharp Enough

1. Press “SMART PICTURE”. In case picture improves, decrease the "Contrast" value. The new value(s) are automatically stored for all TV channels.

2. Check in CSM line CONTRAST. If the value of this line is high (> 50), decrease the "Contrast" value.

5.3.2 Sound Problems

No Sound from Left and Right Speaker

Check in CSM line VOLUME. If the value is high, increase the value of “Volume”. The new value(s) are automatically stored (in “personal” pre-set) for all TV channels.

Sound too Loud for Left and Right Speaker

Check in CSM line VOLUME. If the value is low, decrease the value of “Volume”. The new value(s) are automatically stored (in “personal” pre-set) for all TV channels.

5.4 ComPair

5.4.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products. ComPair is a further development on the European DST (service remote control), which allows faster and more accurate diagnostics. ComPair has three big advantages:

• ComPair helps you to quickly get an understanding on how to repair the chassis in a short time by guiding you systematically through the repair procedures.

• ComPair allows very detailed diagnostics (on I is therefore capable of accurately indicating problem areas. You do not have to know anything about I yourself because ComPair takes care of this.

• ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away.

5.4.2 Specifications

ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. For this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector.

The ComPair faultfinding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways:

• Automatically (by communicating with the television set): ComPair can automatically read out the contents of the

2

C level) and

2

C commands

Service Modes, Error Codes, and Fault Finding

EN 13ES1E 5.

entire error buffer. Diagnosis is done on I2C level. ComPair can access the I and receive I

2

C bus of the television. ComPair can send

2

C commands to and from the micro controller of the television set. In this way, it is possible for ComPair to communicate (read and write) to devices on the I busses of the TV-set.

• Manually (by asking questions to you): This option is helpful, because automatic diagnosis is only possible if the micro controller of the television is working correctly (also, the diagnostic possibilities of automatic diagnosis are more limited). When you choose manual diagnosis, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen give a picture? Click on the correct answer: YES / NO) and by showing you examples (e.g. Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope). You can answer by clicking on a link (e.g. a piece of text or a waveform picture) that will bring you to the next step in the faultfinding process.

By a combination of automatic diagnostics and an interactive question / answer procedure, ComPair will enable you to find most problems in a fast and effective way.

Besides fault finding, ComPair provides some additional features like:

• Up- or downloading of pre-sets.

• Managing of pre-set lists.

• Emulation of the Dealer Service Tool (DST).

• If both ComPair and SearchMan (Electronic Service Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink.

Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Mono-carrier.

– Click on the “Panel” hyperlink to automatically show

the PWB with a highlighted capacitor C2568.

– Click on the “Schematic” hyperlink to automatically

show the position of the highlighted capacitor.

• SW upgrading

5.4.3 How To Order

When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them.

C

5.5.2 How to Read the Error Buffer

Use one of the following methods:

• On screen via the SAM (only if you have a picture). Examples: – 0 0 0 0: No errors detected – 6 0 0 0: Error code 6 is the last and only detected error – 9 6 0 0: Error code 6 was first detected and error code

9 is the last detected error

• Via the blinking LED procedure (when you have no picture). See next paragraph.

•Via ComPair.

5.5.3 How to Clear the Error Buffer

Use one of the following methods:

• By activation of the “CLEAR ERRORS” command in the SAM menu.

• With a normal RC, key in sequence “MUTE” followed by “062599” and “OK”.

• When you transmit the commands “DIAGNOSE” - “99” “OK” with ComPair (or with a DST).

• If the content of the error buffer has not changed for 50+ hours, it resets automatically.

5.5.4 Error Codes

The function of error codes is to indicate failures in the TV set. In principle a unique error code is available for every:

2

•I

C device error.

2

•I

C bus error (for every bus containing two or more I2C

devices).

• Protection error (e.g. +8V protection or Horizontal protection).

• Error not related to an I

2

C device, but of importance (e.g.

BC-loop, RAM error).

5.5 Error Codes

5.5.1 Introduction

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right. When an error has occurred, the error is added to the list of errors, provided the list is not full or the error is a protection error. When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained), except when the error is a protection error. To prevent that an occasional error stays in the list forever, the error is removed from the list after 50+ operation hours.

Service Tips:

• In case of non-intermittent faults, clear the error buffer before you begin the repair. This to ensure that old error codes are no longer present. Before clearing the buffer, write down the content, as this history can give you significant information.

• If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

operation” mode and in “protection” mode). In order to avoid confusion with RC5 signal reception blinking, this LED blinking procedure is terminated when an RC5 command is received.

• Transmit the commands “MUTE”, “06250x”, and “OK” with a normal RC (where “x” is the position in the error buffer that has to be displayed). With x= 1, the last detected error

is shown, x= 2 the second last error, etc.... When x= 0, all

errors are shown.

• “DIAGNOSE X” with the DST (where “x” is the position in the error buffer that has to be displayed). With x= 1, the last

detected error is shown, x= 2 the second last error, etc....

When x= 0, all errors are shown.

Note: It can take some seconds before the blinking LED starts.

5.7 Software Downloading

In this chassis, you can upgrade the software via ComPair. You can find more information on how this procedure works in the ComPair file. It is possible that not all sets are equipped with the hardware, needed to make software upgrading possible. To speed up the programming process the firmware of the ComPair interface can be upgraded. See paragraph “How To Order” for the order numbers.

5.6 The Blinking LED Procedure

5.6.1 Introduction

Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful for fault finding, when there is no picture.

When the SDM is activated, the front LED will show (by blinking) the contents of the error-buffer. Error-codes > 10 are shown as follows:

1. A long blink of 750 ms (which is an indication of the decimal digit),

2. A pause of 1500 ms,

3. “n” short blinks (where “n” = 1 - 9),

4. When all the error-codes are displayed, the sequence finishes with a LED blink of 3000 ms,

5. The sequence starts again.

Example: Error 12 9 6 0 0. After activation of the SDM, the front LED will show:

1. 1 long blink of 750 ms (which is an indication of the decimal digit) followed by a pause of 1500 ms,

2. 2 short blinks of 250 ms, followed by a pause of 3000 ms,

3. 9 short blinks of 250 ms, followed by a pause of 3000 ms,

4. 6 short blinks of 250 ms, followed by a pause of 3000 ms,

5. 1 long blink of 3000 ms to finish the sequence,

6. The sequence starts again.

5.6.2 How to Activate

Use one of the following methods:

• Activate the SDM (only via soldering pads marked “FOR SERVICE” on the SSB). The blinking front LED will show the entire contents of the error buffer (this works in “normal
