Safety Instructions, Warnings, and NotesEN 4 EM1.1A AA2.
2. Safety Instructions, Warnings, and Notes2.1 Safety Instructions
Index of this chapter:2.1 Safety Instructions2.2 Maintenance Instructions2.3 Warnings2.4 Notes
Safety regulations require that during a repair: Due to the chassis concept, a very large part of the chassis
(including horizontal and vertical deflection) is 'hot.' Connect the set to AC power via an isolation transformer.
Safety components, indicated by the symbol , must be replaced with original PCEC components.
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 particular attention to the following points: General repair instruction: as a strict precaution, we advise
you to resolder the solder connections through which the horizontal deflection current is flowing, in particular:1. All pins of the line output transformer (LOT.)2. Flyback 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 resoldering 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 AC power cord for external
damage. Check the strain relief of the 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 AC plug and the secondary side (only for sets that have an isolated power supply.) To do this:1. Unplug the AC power cord and connect a wire between
the two pins of the AC plug.2. Set the AC power switch to the on position (keep the
AC power cord unplugged.)3. Measure the resistance value between the pins of the
AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 Mohm and 12 Mohm.
Check the cabinet for defects, to prevent the customer from touching any inner parts of the television set.
2.2 Maintenance Instructions
It is recommended to have a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions: When the set is used under normal circumstances, for
example in a living room, the recommended interval is three to five years.
When the set is used 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 Fig. 2-1 to discharge the picture tube. Use a high voltage probe and a multimeter (position Vdc.) Discharge until the meter reading is 0 V (after approx. 30s.)
Figure 2-1 Discharge picture tube
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD. ) Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set by a wristband with resistance. Also keep components and tools at this potential.
Available ESD protection equipment: Complete kit ESD3 (small table mat, 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. Adjustment of this unit during repair is therefore not recommended.
Be careful during measurements in the high voltage section and on the picture tube.
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.
2.4 Notes
2.4.1 General
Measure the voltages and waveforms with regard to the chassis (= tuner) ground (), or hot ground (), depending on the area of circuitry being tested.
The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz; unless stated otherwise) and picture carrier at 61.25 MHz (NTSC, channel 3.)
Where necessary, measure the waveforms and voltages with () and without () aerial signal. Measure the voltages in the power supply section both in normal operation () and in standby (.) These values are
V
CL96532156_040.eps140501indicated by means of the appropriate symbols.
Safety Instructions, Warnings, and Notes EN 5EM1.1A 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 ( = x10-6), Nano-Farads (n = x10-9), or Pico-Farads (p = x10-12).
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 Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from 1.1.2005 onwards. Lead-free sets will be indicated by the PHILIPS-lead-free logo on the Printed Wiring Boards (PWB):
Figure 2-3 Lead-free logo
This sign normally has a diameter of 6 mm, but if there is less space on a board also 3 mm is possible.
In case of doubt wether 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 mix of
two alloys).Caution: For BGA-ICs, you must use the correct temperature-profile, 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-helpdesk.
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 at least a solder-tip temperature of 400C. To stabilise the adjusted temperature at the solder-tip. To exchange solder-tips for different applications.
Adjust your solder tool so that a temperature around 360C - 380C is reached and stabilised at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400C, otherwise wear-out of tips will rise 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 not to avoid, clean carefully 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 short 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 90C) for drying (think of ESD-protection !).Do not re-use BGAs at all!
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.
2.4.4 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 - 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 which is causing the problem; the High Voltage Transformer or the lead (if it is removable.

5.1 Test conditions
Perform measurements under the following conditions: Service mode: SDM (Service Default Mode). Video: color bar signal. Audio: 1kHz, mono.
5.2 Service Modes
The Service Default Mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Menu (CSM) is used for communication between the servicer and the 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, error code reading, and software version readout for this chassis.Minimum requirements: a 486 processor, Windows 3.1 and a CD-ROM drive (see 'ComPair' section).
5.2.1 Service Default Mode (SDM)
Purpose Provide a situation with predefined settings in order to
retrieve the same measurement results as published in this manual.
Start the blinking LED sequence procedure. Have the possibility to override the 5V protection.
Specifications Tuning frequency: 475.25 MHz for PAL. Colour system: PAL B/G. All picture settings at 50% (brightness, color, picture). All sound settings at 50% except volume at 25% (bass,
treble, and balance at 50%, volume at 25%). All service-unfriendly modes (if present) are disabled, such
as: (sleep) timer, child/parental lock, blue mute, hotel/hospitality mode, auto switch-off (when no video signal is received for 15
minutes), skip/blank of non-favorite presets/channels, auto store of personal presets, auto user menu time-out.
How to enter SDMUse one of the following methods: Press the following key sequence on the remote control

5.2.3 Customer Service Mode (CSM)
PurposeWhen a customer is having problems with his TV set, the service technician can 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 are not possible in this mode.
How to enter CSMThe CSM will be turned on after pressing the MUTE key on the remote control transmitter and any of the control buttons on the TV for at least 4 seconds simultaneously. This activation only works if there is no menu on the screen.
Line 1:HRS: Hexadecimal counter of operating hours. Example: 1B (hex)= 0001 1011 (binary)= 27 (decimal).Standby hours are not counted as operating hours. Note: every time the set is turned on, the counter will advance one hour.
SWID: Software identification of the main microprocessor (see explanation of software version in the Service Alignment Mode section).
Line 2:Error code buffer (for more details see Error buffer section). Displays the last 7 errors of the error code buffer.
Line 3:Option bit setting controls the software and hardware functionality. An option byte or option number represents 8 of those bits. Each option number is displayed as a decimal number between 0 and 255. The set may not work correctly
when an incorrect option code is set. See Alignments section for more information on correct option settings.

Line 6:Indicates whether the SLEEPTIMER function is ON/OFF. This is displayed by 'TIMER ON.'
Line 7:Indicates whether the CHILD LOCK function is ON/OFF. This is displayed by 'CHANNEL LOCKED.'
Line 8:Indicates whether the current channel is defined as SKIPPED or NOT PREFERRED.
Line 9:Not valid.
Line 10:Indicates the source at entry to CSM: Channel number or External source name (AV1, AV2, AV3, AV4, CVI).
Line 11:Indicates which sound mode is installed for this channel: Mono, Stereo, or SAP.
Line 12 to 17:Values indicate parameter levels of volume, balance, hue, color, brightness, and picture at CSM entry.
How to exit CSMThe Customer Service Mode will switch off after pressing any key on the remote control transmitter (except the 'channel +' or 'channel -' key) or turning off the TV set with the 'POWER' button on the remote control transmitter or the television set.
5.3 Problems and Problem Solving Tips
5.3.1 Picture Problems
TV switches off or changes channel without any user actionThe TV set switches off after 'TV SWITCHING OFF' was displayed.Auto standby switched the set off because: There was no signal identification signal for more than 15
minutes. There was no remote control transmitter signal received or
local key pressed for over 2 hours.
See Alignments section for a description of the options to enable/disable auto standby (option SBNP).

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 of the DST (special remote control transmitter for Service), which allows faster and more accurate diagnostics. ComPair has three big advantages:ComPair helps you to quickly get an understanding how to repair this chassis in a short time by systematically guiding you 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/ EM1.1A electronic service manual, schematics and CBAs 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 at the rear side of the set.
The ComPair faultfinding program is able to detect and diagnose problems occurring in the product. 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 microprocessor of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the television set.
Manually (by asking questions to you): Automatic diagnosis is only possible if the microprocessor of the television is working correctly and only to a certain extent. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (for example, Does the screen give a picture? Click on the correct answer: YES/NO) and showing you examples (for example, Measure test point I7 and click on the waveform you see on the oscilloscope). You can answer by clicking on a link (for example, 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: Emulation of the Dealer Service Tool (DST). If both ComPair and SearchMan / Force (Electronic
Service Manual) are installed, all the schematics and the CBAs of the set are available by clicking on the appropriate hyperlink. Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Monocarrier. Click on the Panel hyperlink to automatically show
the CBA with a highlighted capacitor C2568. Click on the Schematic hyperlink to automatically
show the electronic position of the highlighted capacitor.
5.4.3 How to connect the ComPair Interface
1. First, install the ComPair Browser software on your PC (read the installation instructions carefully).
2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked 'PC') of the ComPair interface.
3. Connect the AC power adapter to the supply connector (marked with 'POWER 9V DC') on the ComPair interface.
4. Switch the ComPair interface OFF.5. Switch the television set OFF.6. Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface (marked with ' I2C ') and the ComPair connector on the mono carrier (see ComPair interface connection figure).
7. Plug the AC power adapter in the AC power outlet and switch on the interface. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit.
8. Start ComPair and select 'File' menu, 'Open...' select 'EM1.1A Fault finding' and click 'OK'.
9. Click on the icon to switch the communication mode 'ON' (the red LED on the ComPair interface will light up).
10. Apply AC power to the television set with the 'POWER' switch.
11. If the set is in STANDBY, click on 'Start up in ComPair mode from standby' in the ComPair EM1.1A faultfinding tree; otherwise, continue.

The set has now started up in ComPair mode. Follow the instructions in the faultfinding tree to diagnose the set. Note that the OSD works, but the actual user control is disabled
5.5 Error Buffer
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. When an error occurs that is not yet in the error code buffer, it is written at the left side and all other errors shift one position to the right.
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: 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 'The Blinking LED Procedure' section. Via ComPair.
5.5.3 How to Clear the Error Buffer
Use one of the following methods to clear the error buffer: Activate the 'CLEAR ERRORS' command in the SAM
menu. Transmit the command 'DIAGNOSE-99-OK' with ComPair. If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
5.5.4 Error Codes
If the set has non-intermittent faults, clear the error buffer before starting repairs. This is to ensure that old error codes are not present.
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 of the problem). For example, a fault in the protection detection circuitry can also lead to a protection.
Table 5-1 Error Codes
Explanation of error codes:Error 0No errors
Error 1FBX 3V3 protectionThis protection is activated when the PICNIC (pos. 7709 on diagram B3) cannot communicate via I2C for a certain time. This could mean that stabilizer 7009 (B7) or 7713 (B3) on SSB (depending on the set) is defective. When there is a short circuit to ground behind the stabilizer, 7009 or 7713 could become very hot. For safety reasons, the set will switch to protection mode.
Error 2No Horizontal Flyback protectionThe HOP (pos. 7301 on diagram B4 detects the absence of an HFB pulse (pin 3 of connector 1424 on LSP, diagram A3)). A bit will be set in the HOP. After filtering by the software, the set will switch to protection mode.
Error 4+5V protectionWhen the +5V protection is active, the set is switched to protection mode and error code 4 is placed in the error buffer. The LED will blink 4 times (repeatedly). A 5V failure can cause a drop in the 5V supply output, resulting in an undefined behavior of the set. Therefore, some I2C devices (Tuner and MSP) connected to the 5V supply are constantly monitored. When none of these devices responds to the microprocessor for a prolonged time, the microprocessor assumes that there is a failure in the 5V supply.By starting up (by disconnecting/reconnecting the set from the mains) the set while short-circuiting the SDM solder pads on the SSB, the +5V protection will be overridden, and it will be easier to determine the cause. The +5V protection will be activated when these I2C devices fail (no I2C communication): Main Tuner (pos. 1200 on the LSP), MSP3452 sound processor (pos. 7651 on the SSB).

The following tips are useful to isolate the problem area, after overriding the +5V protection. Determine whether: The MSP sound processor is loading the +5V; isolate 3650
and/or 4604 (see diagram B6). The main Tuner is loading the +5V source; isolate coil
5901.
Error 5HOP POR errorWhen the POR bit is not communicated during startup, the processor will generate 'HOP POR not successful.'

Note: Error codes 1, 2, 4, and 7 are protection codes, and in this case supplies of some circuits will be switched off. Also, in protection, the LED will blink the number of times equivalent to the most recent error code.
5.6 The 'Blinking LED' Procedure
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 entered, the LED will blink the contents of the error buffer.Error codes > 10 are shown as follows: a long blink of 750ms (which is an indication of the decimal
digit), a pause of 1.5s, n short blinks (n = 1 - 9), when all the error codes are displayed, the sequence
finishes with a blink of 3s, the sequence starts again.
Example of error buffer: 12 9 6 0 0After entering SDM: 1 long blink of 750ms followed by a pause of 1.5s, 2 short blinks followed by a pause of 3s, 9 short blinks followed by a pause of 3s, 6 short blinks followed by a pause of 3s, 1 long blink of 3s to finish the sequence, the sequence starts again.
Note: If errors 1, 2, 4 or 7 occur, the LED always gives the most recent error, even if the set is NOT in service mode.
5.7 Protections
5.7.1 General
This chassis has only one microprocessor (Painter) which remains active during Standby. This is because power for the microprocessor and the memories comes from the 3V3 supply, which is derived from the 5V Standby circuitry. Therefore, in both Power On and Standby mode the microprocessor is connected to this power supply.
If a fault situation is detected, an error code will be generated, and if necessary, the set will be put in the protection mode. The protection mode is indicated by blinking of the LED (at a frequency of 3Hz). In some error cases, the microprocessor does not put the set in the protection mode. The error codes of the error buffer can be read via the service menu (SAM), the blinking LED procedure, or via DST/ComPair.
To get a quick diagnosis, this chassis has 3 service modes implemented: The Customer Service Mode (CSM). The Service Default Mode (SDM). Startup of the set in a
predefined way. The Service Alignment Mode (SAM). In this mode, items of
the set can be adjusted via a menu and with the help of test patterns.
The Protection Diagram shows the structure of the protection system. See diagram below.
Service Modes, Error Codes, and Fault FindingEN 16 EM1.1A AA5.
Figure 5-2 Protection diagram
There are several types of protections: I2C related protections (for example, +5V supply check). HOP related protections (mainly for deflection items). Hardware errors which are not sensed by the Painter (for
example, BRIDGE_PROT)
I2C related protectionsIn normal operation, some registers of the I2C controlled ICs will be refreshed every 200ms. During this sequence, the I2C busses and the I2C ICs will be checked. The I2C protection will take place if the SDA and SCL are short-circuited to ground or to each other. An I2C error can also occur if the power supply of the IC is missing (for example, FBX_PROT: error 1).
HOP related protectionsEvery 200ms, the status register of the HOP is read by the Painter via I2C. If a protection signal is detected on one of the inputs of the HOP, the relevant error bit in the HOP register is set to high. If the error bit is still high after 1s, the Painter will store the error code in the error buffer (NVM) and, depending on the relevance of the error bit, the set may or may not go into protection mode.
HFB: Horizontal Flyback. If the horizontal flyback is not present, then this is detected via the HOP (HFB_X-RAY_PROT). One status bit is set to high. The error code is stored in the error buffer and the set will go into the protection mode.
Flash detection. From the EHT info, via D6303 and T7303, a flash will stop the H-drive and line output stage immediately. The FLS bit in the status register of the HOP is set to high. As the duration of a flash is very short, the FLS bit will be reset to low again after the flash refresh, and the set will be started again via a slow start.
Hardware related protectionsDue to the architecture (with hot deflection) there are two protections that are unknown to the microprocessor, namely the 'BRIDGE_PROT' (coming from the line stage) and the 'DEFL_PROT' protection (coming from the frame deflection stage).If one of these protections is triggered, the set is switched to Standby mode. The Painter will now try to restart the set. If this does not succeed after 5 times (after 30 - 60 seconds), the
causes, such as repeating flashes, BRIDGE_PROT/Non VFB leading to DEFL_PROT, or a serious AC power dip). The red LED will start blinking.
5.8 General tips and repair tips
5.8.1 General
Notice that a very large part of the set (Large Signal Panel) is hot, meaning the primary part of the Standby supply, the whole Main supply (except for the secondary Audio supply), and the complete deflection circuit are "hot."Note: The deflection-coil is hot.
This set is not equipped with an IR transmitting LED. Instead, a Service (ComPair) connector is implemented at the rear of the set, which is directly accessible (it is not necessary to remove the back cover to access the connector).In addition to this, there is a blinking LED procedure to show the contents of the error buffer.
The relay you hear during switching the set on (via the power switch) is from the degaussing circuitry. So it is not used for switching the supply as in the MG chassis.
When there is a menu on the screen, it is not possible to enter a service mode. Be sure there is no menu on the screen when attempting to enter a service mode.
5.8.2 Main Power Supply
The simplest way to repair the main supply is to check (and replace, if necessary) the gray marked components on the Main Supply.
Do not try to perform measurements on the side of the SSB connected to the "hot" heatsink. This is dangerous. Most relevant service test points are connected to the Tuner side and are pointed out by service printing. Where the circuitry was too crowded to place this service printing, it has been explained on the Test Point Overviews in this manual. It is also possible to use the SSB extension panel (part number: 9965 000 05769), so that all test points are easily accessible.
5.8.3 Standby Power Supply
The simplest way to repair the standby supply is to check (and replace, if necessary) the gray marked components on the Standby Supply.
5.8.4 Horizontal Deflection
The simplest way to repair the horizontal deflection is to check (and replace, if necessary) the gray marked components on the Horizontal Line Deflection circuitry.
5.8.5 Vertical Deflection
Caution: When you suspect the Vertical Deflection circuitry, please be careful. Since there is a DC voltage on the vertical deflection, the beam current can damage the CRT neck, leading to a defective CRT.The best thing to do is:1. Interrupt pin 2 of connector 1424 on the CRT panel
(diagram F), in order to remove the 'filament' voltage from the tube (there is no beam current, so there is no chance of destroying the CRT).
2. Measure the functionality of the Frame stage with a multimeter or with an oscilloscope.
3. After you have found the cause, exchange the defective component (for example, TDA8177), and resolder the
