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 that 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 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 (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 which 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 avoid 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 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 (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.

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 given in micro-farads (µ= x10 nano-farads (n= 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 Spare Parts List. Therefore, always check this list when there is any doubt.

Figure 2-2 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. Regardless of this logo (is not always present), one must treat all sets from this date onwards according to the following rules
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
-12
– To reach at least a solder-tip temperature of 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 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 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

),
).

2.4.4 Practical Service Precautions

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.
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 mix 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.
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.

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.

The new “Personal” preference value is automatically stored.
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 (located on the Main panel, (see figure "Top view Mono Carrier" in chapter 8 "Alignments").
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 I can access the I and receive I

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 extent. 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 oscillogram 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.
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.

detected error
– ERROR: 9 6 0 0 0: Error code 6 was first detected and
error code 9 is the last detected (newest) error
Via the blinking LED procedure (when you have no picture). See next paragraph.
•Via ComPair.

5.4.7 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:
By activation of the CLEAR command in the SDAM menu:
If the content of the error buffer has not changed for 50 hours, it resets automatically.
Note:
When leaving SDAM by disconnecting the set from AC power, the error buffer is not reset.
Page 10
EN 10 L03.2L AA5.

5.5 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure that old error codes are no longer 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 (e.g., a fault in the protection detection circuitry can also lead to a protection).

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 when there is no picture.
When the SDAM is entered, the LED will blink the contents of the error-buffer.
n short blinks (n = 1 - 14),
When all the error-codes are displayed, the sequence finishes with a LED blink of 3 s,
The sequence starts again.
Example of error buffer: 12 9 6 0 0 After entering SDAM:
12 short blinks followed by a pause of 3 s,
9 short blinks followed by a pause of 3 s,
6 short blinks followed by a pause of 3 s,
1 long blink of 3 s to finish the sequence,
the sequence starts again.

5.7 Protections

If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. 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 (SDAM), the blinking LED procedure or via ComPair.
To get a quick diagnosis the chassis has one service modes implemented:
The Service Default Alignment Mode (SDAM). Start-up of the set in a predefined way and adjustment of the set via a menu and with the help of test patterns.

5.8 Repair Tips

Below some failure symptoms are given, followed by a repair tip.
Set is dead and makes hiccupping sound. “Main Supply” is available. Hiccupping stops when de-soldering L5563, meaning that problem is in the “Main Supply” line. No output voltages at LOT, no horizontal deflection. Reason: line transistor 7421 is defective.
Set is dead, and makes no sound. Check power supply IC 7520. Result: voltage at pins 2, 6, 7, 9 and 11 are about 180 V and pin 14 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load. That is why MOSFET 7521 is not able to switch. Reason: feedback resistor 3523 is defective. Caution: be careful measuring on the gate of 7521; circuitry is very high ohmic and can easily be damaged!
Set is in hiccup mode and shuts down after 8 s. Blinking LED (set in SDM mode) indicates error 5. As it is unlikely that the “POR” and “+8V protection” happen at the same time, measure the “+8V”. If this voltage is missing, check transistor 7491 and 7496.
Set is non-stop in hiccup mode. Set is in over current mode; check the secondary sensing (opto coupler 7515) and the “Main Supply” voltage. Signal “Stdby_con” must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.
Set turns on, but without picture and sound. The screen shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As “Vlotaux+5V” at pin 5 and 7 are okay, “VT_supply” at pin 9 is missing. Conclusion: resistor 3449 and 3450 are defective

8.3 Software Alignments and Settings

The following options are performed in the Service Default Alignment Mode (SDAM). SDAM is described in the "Service Modes, Error Codes and Fault Finding" section. The following alignments are explained:
1. OPTIONS
2. TUNER
3. WHITE TONE
4. GEOMETRY
5. AUDIO

8.3.1 OPTIONS

Options are used to control the presence or absence of certain features and hardware.
Note: Each option byte controls several features of the television set; therefore, before changing option byte information, it is important to record the current option byte values. This ensures that the television features can be restored to the original settings, if necessary.
How to Change an Option Byte
An Option Byte represents a number of different options. Changing these bytes directly makes it possible to set all options very fast. All options are controlled via seven option bytes. Select the option byte (OP 1.. OP 7) with the MENU UP/ DOWN keys, and enter the new value.
Leaving the OPTION submenu saves the changes in the Option Byte settings. Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start).
How to Calculate the Value of an Option Byte
Calculate an Option Byte value (OP 1 .. OP 7) in the following way:
1. Check the status of the single option bits (OB): are they enabled (1) or disabled (0).
2. When an option bit is enabled (1), it represents a certain value (see first column "value between brackets" in table below). When an option bit is disabled, its value is 0.
3. The total value of an Option Byte is formed by the sum of its eight option bits. See second table below for the correct Option Bytes per type number.

Figures can deviate slightly from the actual situation, due to different set executions.
For a good understanding of the following circuit descriptions, please use the block diagram in chapter 6, and/or the electrical diagrams in chapter 7. Where necessary, you will find a separate drawing for clarification.
9.1 Introduction
The "L03"' chassis is a global TV chassis, and is used for TV sets with screen sizes from 14 inch to 21 inch, in Super Flat and Real Flat executions. In comparison to its predecessor (the "L01"), this chassis is further simplified: it contains economized executions of the power supply, the video processing (microprocessor), and the audio processing. Due to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control.
The standard architecture consists of a Main panel (called "family board") and a Picture Tube panel. The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part.
The functions for video processing, microprocessor (µP), and CC/Teletext (TXT) decoder are combined in one IC (TDA937x), the so-called Ultimate One Chip (UOC). This chip is mounted on the component side of the main panel.
The L03 can be divided into two basic systems, i.e. mono and stereo sound. While the audio processing for the mono sound is done in the audio block of the UOC, external audio processing ICs are used for stereo sets.
The tuning system features 181 channels with on-screen display. The main tuning system uses a tuner, a microcomputer, and a memory IC mounted on the main panel. The microcomputer communicates with the memory IC, the customer keyboard, remote receiver, tuner, signal processor IC and the audio output IC via the I the settings for favorite stations, customer-preferred settings, and service / factory data. The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal.
The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source. The chassis has a 'hot' ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis.

9.2 Source Selection
The Source Select is divided mainly into two types, the "Mono Source Select" and the "Stereo Source Select".
The Mono Source Select, both audio and video, will be done entirely by the UOC and will only be able to select one external audio source.
As for the Stereo Source Select, the Panasonic IC, which is for BTSC decoding also, has 2 audio source inputs used for source selection, whereas the UOC will take care of the video selection.

9.2.1 Switching Function for Stereo I/O

Audio / Video Source Selection
The video source selection is done by the UOC. The video setting for LATAM / NAFTA is rather straightforward: a so­called "WYSIWYG" (what you see on the screen, is what you get from the video ouput). There is only a front input available, therefore the source selection is basically limited to the UOC.

9.2.2 Switching Function for Mono I/O

For the Mono configuration, only one input pin is available for the UOC.
Video Source Selection
The video switching is similar to the section above.
Audio Source Selection
The audio input (L1_IN) is connected to pin 35 of the UOC.
9.3 Audio
This chassis is targeted for the NAFTA market with Mono, Stereo, or SAP sound system. For the "basic" Mono and Stereo sets, sound processing includes Volume control and AVL. For stereo sets, IC TDA9853H is the BTSC audio signal decoder and audio processing..

9.3.1 Processing

This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio). The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder. The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono, Stereo, and/or SAP. Based on this indication, the software controls will help to output the appropriate audio signal at pins 21 and 22. The controls are done by the I connected to pins 18 and 19. Internal or External audio (pins 2, 3, 23, and 24) can also be selected by the source selection register. For the selected audio source, the AGC function can be applied. The output is a fixed level output. The volume control function is available via the power amplifier (AN7522/23).

9.3.2 Amplifier

The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets). This is a BTL amplifier (Bridge Tied Load), which is actually a class AB amplifier with four transistors for each channel. The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output.

The volume level is controlled at this IC (pin 9) by the "VOLUME" control line coming from the microprocessor. After amplification, the audio signal is sent to the speaker / headphone output connector.

9.3.3 AVL (Automatic Volume Limiting)

The "Mono AVL" function operates via the UOC. During channel change and source selection, the AVL bit is to be switched "off" and then can return to the previous state ("on/ off") as shown in the timing diagram below.
The "Stereo AVL" function operates via the AGC control of IC TDA9853H. During channel change and source selection, the AGC function is to be switched "off" and then can resume to the previous state ("on/off") as shown in timing diagram below.

with the incoming CVBS signal. They are then fed to the H- and V-drive circuits and to the OSD/TXT circuit for synchronization of the On Screen Display and Teletext (CC) information.

9.6 Deflection

For a detailed circuit description of this part, we refer to the L01.2L AA manual (see the beginning of this chapter for the ordering codes). Please note that there can be minor differences in the text (e.g. other item numbers), but the described circuit principle is comparable.
The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture. For the chassis architecture, the CRTs used do not need East/West Correction. Therefore the geometry correction needed is horizontal shift, vertical slope, vertical amplitude, vertical S-correction, vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets).

9.7 Power Supply

For a detailed circuit description of this part, we refer to the L01.2L AA manual (see the beginning of this chapter for the ordering codes). Please note that there can be minor differences in the text (e.g. other item numbers), but the described circuit principle is comparable.
Figure 9-1 AVL timing diagram

9.3.4 Mute

The TV set must mute:
Whenever a "User Mute" is activated.
Whenever there is a channel change, RF to RF, RF to AV, AV to RF, and AV to AV (if any). In channel change, MUTE must be activated first before any other activity and un­MUTE must be done after every other activity has been completed.
Whenever there is a loss in the signal.
During cold or warm start, MUTE must be activated until all initialization processes are finished.
When the set is going to STANDBY, MUTE must be activated first before any other activities.
Note:
1. MUTE mentioned above applies to the audio amplifier mute (= PWM volume control mute).
2. The first condition does not apply for the UOC, IC TDA9853H.
3. Above conditions refers to both mono and stereo sets.

9.4 Video

For a detailed circuit description of this part, we refer to the L01.2L AA manual (see the beginning of this chapter for the ordering codes). Please note that there can be minor differences in the text (e.g. other item numbers), but the described circuit principle is comparable.
This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC), which is mounted in an SDIP 64 envelope. The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed Caption/TXT decoder.

9.7.1 Introduction

The supply is a Switching Mode Power Supply (SMPS). The frequency of operation varies with the circuit load. This 'Quasi­Resonant Flyback' behavior has some important benefits compared to a 'hard switching' fixed frequency Flyback converter. The efficiency can be improved up to 90%, which results in lower power consumption. Moreover, the supply runs cooler and safety is enhanced. The control IC in this power supply is the TEA1506 (L01= TEA1507). Unlike the TEA1507 control IC, the TEA1506 has no internal high voltage start-up source, and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507). The operating voltage for the driver circuit is also taken from the 'hot' side of this transformer. The switching regulator IC 7520 starts switching the FET 'on' and 'off', to control the current flow through the primary winding of transformer 5520. The energy stored in the primary winding during the 'on' time is delivered to the secondary windings during the 'off' time. The "MainSupply" line is the reference voltage for the power supply. It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 / 6540. This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520. The power supply in the set is "on" any time AC power is connected to the set.

9.7.2 Derived Voltages

The voltages supplied by the secondary windings of T5520 are:
"MainSupply" for the horizontal output.
•"V
aux/Vaudio
An optional "DVD
" for the audio circuit.
" for future extensions.
Supply
Other voltages are provided by the LOT. It supplies -12 V, the tuner voltage, the filament voltage, and the +160 V source for the video drive. These secondary voltages of the LOT are monitored by the "EHT" lines.

9.5 Synchronization

Inside IC7200 (part D) the vertical and horizontal sync pulses are separated. These "H" and "V" signals are synchronized

9.8 Control

9.8.2 User Interface

9.8.3 I/O Selection

9.8.4 Power Supply Control

C-Bus
The main control system, which consists of the microprocessor part of the UOC (7200), is linked to the external devices (Tuner, NVM, Audio ICs, etc) by means of the I
2
C-bus. An internal I2C­bus is used to control other signal processing functions, like video processing, sound IF, vision IF, synchronization, etc.
The chassis uses a remote control with RC5 protocol. The incoming signal is connected to pin 67 of the UOC. The keyboard, connected to UOC pin 8, can also control the set. Button recognition is done via a voltage divider. The front LED (6691) is connected to an output control line of the microprocessor (pin 11). It is activated to provide the user information about whether or not the set is working correctly (e.g., responding to the remote control, normal operation (USA only) or fault condition)
For the control of the input and output selections, there are three lines:
STATUS1
This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe). This signal is not connected in LATAM/NAFTA sets.
STATUS2
This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe). For sets with an SVHS input it provides the additional information if a Y/C or CVBS source is present. The presence of an external Y/C source makes this line 'high' while a CVBS source makes the line 'low'.
SEL_AV1_AV2
This is the source select control signal from the microprocessor. This control line is under user control or can be activated by the other two control lines.

C-bus.
This is of logic "high" (3.3 V) under normal operation of the TV. When the TV set is in Standby (or fault) condition, this signal is a continuous pulse of 5 ms "low" (0 V) and 5 ms "high". Note: In the L01 chassis this was inverted.

PW_ADJ
This signal is generated by the UOC through a PWM port. This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100% duty cycle with a default value of 50% duty cycle. PW_ADJ will eliminate tolerance and can adjust the picture wide slightly.

9.8.5 Protection Events

Several protection events are controlled by the UOC. In case one of these protections is activated, the set will go to "Standby" mode.
Deflection protections
The main protections for deflection are X-ray protection, frame amplifier failure detection, black current loop stability protection, and +8V auxiliary supply protection. For X-ray protection, the X-ray detection bit, XDT, must always be set to "1" (detection mode). High EHT protection must be triggered via software upon detection of the XPR bit switching to "1". A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering. For service requirements, the Enable Vertical Guard (RGB blanking), EVG, can be disabled (set to "0") although this is not necessary.
The following bits are monitored:
SUP (Supply voltage indication)
XPR (X-ray protection)
EVG (Enable Vertical Guard)
NDF (Output Vertical Guard)
BCF (Black Current Failure)

180603
The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT. The microprocessor part is supplied with 3.3 V and 8 V. The 3.3 V is derived from the "V
aux/Vaudio
" voltage via a 3V3 stabilizer (7493). The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496. Two signals are used to control the power supply: STD_CON and PW_ADJ.
STD_CON
This signal is generated by the microprocessor when over­current takes place at the "Main" line. This is done to enable the power supply into standby burst mode, and to enable this mode during a protection.
