Safety and Maintenance Instructions, Warnings, and Notes

2. Safety and Maintenance Instructions, Warnings, and Notes

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_dc). Discharge until the meter 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, 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.

2.4 Notes

E_06532_007.eps

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.

2.4.1 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 color 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 standby (F). These values are indicated by means of the appropriate symbols.

Safety and Maintenance Instructions, Warnings, and Notes

EN 5L04U AA 2.

• 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.

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= x 10^-6), nano-farads (n= x 10^-9), or pico-farads (p= x 10^-

12).

• 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.

2.4.3 Practical Service Precautions

• Adjust your solder tool so that a temperature around 217 220 deg. C is reached at the solder joint.

• Do not mix lead-free soldering tin with leaded soldering tin; this will lead to unreliable solder joints!

• Use only original spare parts listed in this manual. These are lead-free parts!

• On the website www.atyourservice.ce.philips.com you can find more information on:

– Aspects of lead-free technology. – BGA (de-)soldering, heating-profiles of BGAs used in

Philips sets, and others

• 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 - 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.

• Before powering up the TV set with the back cover off

(or on a test fixture), attach a clip lead to the CRT DAG ground and to a screwdriver blade that has a well insulated handle. After the TV is powered "on" and high voltage has developed, probe the anode lead with the blade, starting at the case of the High Voltage Transformer (flyback - IFT). Move the blade to within two inches of the connector of the CRT. If there is an arc, you found it the easy way, without getting a shock! If there is an arc to the screwdriver blade, replace the part that is causing the problem: the High Voltage Transformer or the lead (if it is removable).

2.4.4 Lead Free Solder

This set is manufactured with lead-free production technology. This is also indicated on the PWB by the PHILIPS lead-free logo (either by a service-printing or by a sticker).

Figure 2-2 Lead-free logo

This set is produced with lead-free solder alloy as well as with lead-free sub-parts. It can be considered as lead-free. Due to this fact, 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.

• Use only adequate solder tools applicable for lead-free soldering tin.

ONTROLS

he AutoLock™ feature is an integrat-

ed circuit that receives and processes

data sent by broadcasters, or other pro-

gram providers, that contain program

content advisories. When programmed

by the viewer, a TV with AutoLock™ can

respond to the content advisories and

block program content that may be found

objectionable (such as offensive lan-

guage, violence, sexual situations, etc.).

This is a great feature to censor the type

of viewing children may watch.

AutoLock™ offers various BLOCK-

ING controls from which to choose:

Access Code - An Access Code must be

set to prevent children from unblocking

questionable or censored programming

set by their parents.

Channel Block - After an access code

has been programmed, you can block

individual channels including the A/V

inputs.

ClearAll - Allows you clear all channels

being blocked from your viewing set

with the Channel Block Control.

Block All - Allows you to block ALL

channels and A/Vinputs at one time.

Movie Ratings - Certain blocking

options exist which will block program-

ming based on ratings patterned by the

Motion Pictures Association of America.

TV Ratings - Just like the Movie

Ratings, programs can be blocked from

viewing using standard TV ratings set by

TV broadcasters.

“smiley” face appears will tune

all the programmed channels.

Pressing the COLORED button

again will return you to the first

channel in the list.

If the “smiley” face disappears from

the screen and the same COLORED

button is pressed, the surf channels

will be displayed starting with the

FIRST programmed channel again.

Repeat steps 1-3 for the other

three COLORED buttons (Surf

Any time the “smiley” face

appears with the channel num-

ber, pressing the “frownie”

5.2 Service Modes

Service Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call center and the customer.

This chassis also offers the option of using ComPair, a hardware interface between a computer and the TV chassis. It offers the abilities of structured troubleshooting, error code reading, and software version readout for all chassis. Minimum requirements for ComPair: a Pentium processor, a Windows OS, and a CD-ROM drive (see also paragraph "ComPair").

5.2.1 Service Default Mode (SDM)

Purpose

• To create a predefined setting for measurements to be made.

• To override software protections.

• To start the blinking LED procedure.

Specifications

• Tuning frequency: 61.25 MHz (channel 3).

• Color system: NTSC M.

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

• Bass, treble and balance at 50 %; volume at 25 %.

• All service-unfriendly modes (if present) are disabled. The

service unfriendly modes are:

– Timer / Sleep timer. – Child / parental lock. – Blue mute. – Hotel / hospital mode. – Auto shut off (when no “IDENT” video signal is

received for 15 minutes).

– Skipping of non-favorite presets / channels. – Auto-storage of personal presets.

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 I2C level) and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C commands 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. In 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:

• Automatic (by communication with the television):

ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I2C level. ComPair can access the I2C bus of the television. ComPair can send and receive I2C commands to the micro controller of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set.

• Manually (by asking questions to you): Automatic

diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extend. When this is not the case, 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 showing you examples (e.g. Measure test-point I7 and click on the correct waveform you see on the oscilloscope). You can answer by clicking on a link (e.g.

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.

Beside 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.

• Software downloading (as soon as this is supported by

ComPair).

5.4.3 How To Connect

1. First, install the ComPair Browser software (see the Quick

Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial

(COM) port of your PC and the PC connector (marked with

“PC”) of the ComPair interface.

3. Connect the mains adapter to the supply connector

(marked with “POWER 9V DC”) of the ComPair interface.

4. Switch the ComPair interface “off”.

5. Switch the television set “off” with the Power switch.

6. Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface

(marked with “I2C”) and the ComPair (or Service)

connector at the rear side of the TV (for its location see

figure 8 item “D”).

7. Plug the mains adapter in a mains outlet, and switch the

interface “on”. The green and red LEDs light up together.

The red LED extinguishes after approx. 1 second while the

green LED remains lit.
