Safety and Maintenance Instructions, Warnings, and Notes

2. Safety and Maintenance Instructions, Warnings, and Notes

EN 5EM6E 2.

2.1 Safety Instructions

Safety regulations require that during a repair:

• Due to the chassis concept, a very large part of the circuitry (incl. deflection) is 'hot'. Therefore, connect the set to the mains via an isolation transformer.

• 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, you must return the set 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 is flowing. 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 cord for external damage.

• Check the strain relief of the mains 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 plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:

1. Unplug the mains cord and connect a wire between the

two pins of the mains plug.

2. Turn on the main power switch (keep the mains cord

unplugged!).

3. Measure the resistance value between the pins of the

mains plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MΩ and 12 MΩ.

4. Switch the TV 'off' and remove the wire between the

two pins of the mains plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

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 Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position V reading is 0 V (after approx. 30 s).

Figure 2-1 Discharge picture tube

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, symbol 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 potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

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

– Wristband tester 4822 344 13999.

• Together with the deflection unit and any multi-pole unit,

flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. We do not recommend adjusting this unit during repair.

• Be careful during measurements in the high voltage section and on the picture tube.

• Never replace modules or other components while the unit is '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.

). Discharge until the meter

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.

These values are indicated by means of the appropriate symbols.

2.4 Notes

2.4.1 General

• Measure the voltages and waveforms with regard to the

chassis (= tuner) ground (symbol H), or hot ground (symbol 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 (PAL) or 61.25 MHz (NTSC, channel 3).

• Where necessary, measure the waveforms and voltages with (symbol D) and without (symbol E) aerial signal. Measure the voltages in the power supply section both in normal operation (symbol G) and in standby (symbol F).

EN 6 EM6E2.

Safety and Maintenance Instructions, Warnings, and Notes

• The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating.

• 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.

• Manufactured under license from Dolby Laboratories. ‘Dolby’, ‘Pro Logic’ and the ‘double-D symbol’, are trademarks of Dolby Laboratories.

Figure 2-2 Dolby PL Symbol

2.4.2 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 kOhm).

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

• All Capacitor values are expressed in Micro-Farads (µ=

-6

x10

), Nano-Farads (n= x10-9), or Pico-Farads (p= x10

• 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 in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.

aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. To reflow the solder, apply a temperature profile according to the IC data sheet. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times.

2.4.3 Rework on BGA ICs (Ball Grid Array)

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, 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 chance 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 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

5.1 Test Points

The chassis is equipped with test points printed on the circuit board assemblies. They refer to the diagram letters.

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”).

Note: In this chassis, the bi-coloured LED (red/green) is replaced by two separate LEDs, a blue and a red one. The blue LED is controlled by software (via ON_OFF_LED). The red LED will light in anti-phase to the blue, but with a time delay. This means that if the blue LED is blinking fast, the red LED will stay off, but after the blue LED is “OFF” long enough, the red LED will go “ON”. So take care: In certain service modes (e.g. blinking LED, stepwise start-up, etc.) you must observe the blue LED and ignore the red LED.

5.2.1 Service Default Mode (SDM)

Purpose

• To create a pre-defined setting, to get the same measurement results as given in this manual.

• To override SW protections.

• To start the blinking LED procedure.

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. – Smart modes. – Auto store of personal presets. – Auto user menu time-out.

How to enter 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 for a moment the two solder pads on SSP print, with the indication “SDM”. These solder pads are present at both sides of the print. Activation can be performed in all modes, except when the set has a problem with the mainprocessor. Caution: If the SDM is entered via the pins, all the software-controlled protections are de-activated.

• Use the DST-emulation feature of ComPair.

• Use the “DEFAULT” button on the Dealer Service Tool

(RC7150).

After entering this mode, “SDM” will appear in the upper right corner of the screen.

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).

How to exit SDM

Use one of the following methods:

• Switch the set to STANDBY via the RC-transmitter.

• Press the “EXIT” button on the DST.

• Via a standard customer RC-transmitter: key in “00”-

sequence.

5.2.2 Service Alignment Mode (SAM)

Purpose

• To perform (software) alignments.

• To change option settings.

• To easily identify the used software version.

• To view operation hours.

• To display (or clear) the error code buffer.

Specifications

• Operation hours counter.

• Software version.

• Option settings.

• Error buffer reading and erasing.

• Software alignments.

How to enter SAM

Use one of the following methods:

• Via a standard RC transmitter: key in the code “062596” directly followed by the “OSD [i+]” button. After entering SAM with this method a service warning will appear on the screen, you can continue by pressing any digit key on the RC.

• Short for a moment the two solder pads on SSP print, with the indication SAM. These solder pads are present at both sides of the print. Depending on the software version it is possible that the service warning will appear, you can continue by pressing any digit key on the RC.

• Use the DST-emulation feature of ComPair.

• Press the ALIGN button on the DST while the set is in the

normal operation

EN 28 EM6E5.

Service Modes, Error Codes, and Fault Finding

After entering this mode, “SAM” will appear in the upper right corner of the screen.

Contents of SAM:

• OPERATION HOURS. Displays the accumulated total of

operation hours (not the standby hours).

• HARDWARE INFO – ROM VERSION. Displays the date of the software and

the software version of the ROM (example: EM6EU1-

1.0_01234 = AAABBC-X.Y_NNNNN).

• AAA= the chassis name.

• BB= the region: EU= Europe, AP= Asia Pacific

PAL/Multi, AN= Asia Pacific NTSC, US= USA, LT= LATAM.

• 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).

• NNNNN= last five digits of 12nc code software.

– SW VERSION RDS RADIO. Displays the software

version of the RDS radio (if RDS radio is present).

• ERRORS (followed by maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph “Error Codes”).

• DEFECTIVE MODULE. Here the module that generates the error is displayed. If there are multiple errors in the buffer, which are not all generated by a single module, there is probably another defect. It will then display the message “UNKNOWN” here.

• RESET ERROR BUFFER. When you press the “OK” button, the error buffer is reset.

• ALIGNMENTS. This will activate the “ALIGNMENTS” sub- menu.

• DEALER OPTIONS. Extra features for the dealers.

• SERVICE OPTIONS. Extra features for Service.

• INITIALISE NVM. When an NVM was corrupted (or

replaced) in the former EM3 chassis, the microprocessor replaces the content with default data (to assure that the set can operate). However, all pre-sets and alignment values are gone now, and option numbers are not correct. Therefore, this was a very drastic way. In this chassis, the procedure is implemented in another way: The moment the processor recognises a corrupted NVM, the “initialise NVM” line will be highlighted. Now, you can do two things (dependent of the service instructions at that moment): – Save the content of the NVM via ComPair for

development analysis, before initialising. This will give the Philips Service department an extra possibility for diagnosis (e.g. when Development asks for this).

– Initialise the NVM (same as in the past, however now it

happens conscious).

• STORE. All options and alignments are stored when pressing the “OK”-button

• FUNCTIONAL TEST. All devices are tested via the “OK” button. Eventual errors are displayed in the error buffer. The error buffer is not erased, the content returns when this test is terminated.

• DAILY MENUS. With the “OK” button, you can go to the normal user menu. SAM is still active in the background. With the “MENU” button, you return from the user menu to SAM menu. This feature can be helpful to quickly change some settings in the user menu.

• SW MAINTENANCE

• UPGRADE. More info see paragraph Software

downloading.

• EVENTS. Not useful for service purposes. In case of

specific software problems, the development department can ask for this info.

• BDM INFO. Broadcast Debug Menu info. The purpose

of this menu is to debug the broadcast, not the TV. The menu gives an overview of what is received on the current preset. Following items are displayed:

5.2.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can call his dealer. 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 enter CSM

Use one of the following methods:

• Press the “MUTE” button on the RC-transmitter simultaneously with the “MENU” button on the TV (top control) for at least 4 seconds.

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

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

How to navigate

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