Possible complaint: 

Brown colouration of the circuit board near the diode D 60222 BZT 03D180. Simultaneously 

the "+Eco" voltage is approx. 5V too high. 

Reason: 

Coincidence of unfavourable component tolerances. 

Cure: 

Carry out the following changes in the stand-by mains stage: 

- Change the Z-diode D 60203 from ZPD 9.1V to 8.2V. 

- Change R 60202 from 68 kΩ to 1 kΩ. 

- Connect an additional Z-diode ZPD 13 in series with R 60202. Connect the cathode of the 

diode to the base of the transistor CT 60206. 

- Check the rating of the resistor CR 60203 to be 2.2 kΩ. 

Workshop: 

Check the "+Eco" voltage. Carry out the changes if this voltage is higher than +17 V.

Service Information 

Colour television receivers with chassis CUC 7303 and 7305, e.g. P 37-071, 

T 51-720 text, T 55-731 text 


After having replaced EEPROM IC 830 X24C02, the Automatic Tuning 

System does not find all stations. 

Reason: 

The EEPROM on this chassis contains information about so-called band 

limits in its memory cells 235 to 239. These values are programmed in the 

factory in a special alignment adapter and vary with the individual tuner 

and Z-diode D 683 (ZTK 33). When fitting a new EEPROM, any value is 

stored in the memory cells. Consequently, the ATS does not scan the 

complete frequency range. 

Cure: 

Clear the band limit values (content of the memory cells 235 to 239) as 

follows: 

1. Call up the Service Menu (depress button „i“ on the remote control 

while switching on with the mains switch). 

2. With the remote control buttons „P+/P-“ select line „AGC ALIGN“. 

3. During a period of 5 seconds operate the buttons „AUX“ and „OK“ 

sequentially. 

The ATS search function now scans the whole frequency range. 

Note: When the band limits are cleared individual stations may be found 

twice! 

Workshop: 

Clear the band limit values when having replaced the tuner, Z-diode 

D 683 or EEPROM IC 830. 

Stores: 

none 

Note to our Service Information 1/97 (subject: Digi Basic colour television 

receivers - „Eco“ voltage is about 5V too high) 

Due to repeated inquiries we would like to point out that resistor R 60202 

that is to be changed from 68 kΩ to 1 kΩ is a lead-type version and not a 

SMD component.

Colour television receivers with chassis CUC 7350, e.g. ST 55-750 text 


Despite the modifications carried out according to our TV Service 

Information 9/96 the television sets switch occasionally to Standby 

after a prolonged time of operation. 

Reason: 

Temperature drift of the +E operating voltage by about 0.2 to 0.3V 

caused by Z-diode CD 61023. Consequently, IC 34015 TDA 8374 

switches off with sudden black/white changes in the picture content or 

changing scenes. 

This Z-diode has been introduced later and therefore is drawn in only 

in the 1st Supplement to the CUC 7350 Service Manual. 

Cure: 

The position of the Z-diode is X=10, Y=150. Unsolder this diode and 

insert a SMD resistor 1206 1.2Ω 1% in this place.

The sound disappears suddenly during the reception of a satellite 

programme and is audible again only when changing the programme or 

switching the TV off and on again. 

Reason: 

IC MSP 3400 on the SAT Module hangs up by static charges entering the 

Reset input of the IC. 

Cure: 

Unsolder the SMD capacitor CC 3800 from its place on the SAT Module 

and resolder it at the place indicated on the figure below.

The TV receiver can be switched on only with the remote control handset. 

When switching on with the mains switch, the receiver always goes to 

Standby mode. 

Reason: 

Unwanted activation of the protection circuit at the moment the TV 

receiver is switched on. 

Cure: 

Change the electrolytic capacitor C 58004 (on pin 6 of IC 58010) from 

10 μF to 22 μF/25V. 

Workshop: 


Important note: Since the Digi Basic TV receivers work without a wiper 

contact in the mains switch the EEPROM stores the operating mode 

(Standby or „On“) at the time the set is switched off with the mains 

switch. That is why the set will only start with „On“ the next time it is 

switched on (power on) if it was switched off from this mode.

Vertical output stage TDA 4173 fails or thin white lines similar to retrace 

stripes are visible. 

Reason: 

Inherent instability of the vertical output stage IC TDA 4173 AF. 

Cure: 

- Should above mentioned symptoms appear do not fail to exchange 

TDA 4173 AF and solder additionally a 1 nF foil capacitor from pin 1 and 

from pin 7 each to pin 4 (-K voltage) on the copper side. 

- Check the mounting position of the vertical output-IC. If the position of 

the IC is too low, the pins may temporarily come into contact with 

the chassis connection on the upper side causing the IC to fail. 

Additionally, the circuit may already be damaged by the building up 

force of pressure resulting in a long-term failure. Therefore replace 

TDA 4173 AF also if it has not been fitted correctly! 

Workshop: 

When fitting the new IC TDA 4173 AF take care of the correct position of the 

holding clamp and solder in the additional capacitors!

Failure of the RGB output IC‘s TDA 6111. 

Reason: 

The RGB output IC‘s are destroyed by high voltage sparks. 

Cure: 

Directly from the outputs (pin 8) of the three output IC‘s TDA 6111 connect 

one additional diode BAV 21 each to chassis and one diode each to the 

+200 voltage (see figure). 

Workshop: 

The insertion of the three diodes which are to be connected to +200 is 

already prepared on the picture tube panel by the diodes D 734, D 754 and

Product Colour television receivers ST 72-261 IDTV/LOG and ST 72-261/8 IDTV/LOG 

with Toshiba picture tube 


Picture seems to be unsharp or the TV switches occasionally to Standby. 

Reason: 

Short circuit in the serially connected capacitors C 64001 and C 64002 

(150pF/6kV each) on the dynamic focusing board. 

Cure: 

1. Replace the capacitors C 64001 and C 64002 on the dynamic focusing 

board. 

2. Check the Ug2/focus control unit on the picture tube socket board 

29305-122.12. 

If the TV is fitted with version 29201-361.01 or -361.11, this focus control 

unit must be replaced by version 29201-361.04. Version 29201-361.20 

needs not to be replaced but can remain in the TV set. 

3. Attention: When fitting the new Ug2/focus control unit, please note the 

following wiring instructions: 

- Insert the blue lead - provided with a white mark - of the Ug2/focus 

control unit into the focus voltage connection of the diode split 

transformer. 

- Solder the shorter blue lead of the Ug2/focus control on to the focus 

voltage connection of the focusing board. 

- Route this lead from the focusing board to the focus voltageconnection 

of the picture tube socket. 

- Re-attach the cover of the focusing board. 

4. Replace the diode split transformer 29201-680.01. Due to the failure of 

the capacitor C 64001 or C 64002 the resistance of the focus resistor 

in the diode split transformer changes so that an optimum adjustment of 

the picture sharpness is no longer possible. 

Workshop: 

Please check the wiring of the focus leads according to point 3 of every 

TV receiver of type ST 72-261 IDTV/LOG and ST 72-261/8 IDTV/LOG coming 

in for repair! 

Focus adjustment: 

- Feed in a convergence test pattern. 

Set contrast to maximum. Set the brightness so that the black 

background of the test pattern just becomes visible. 

- With the focus control on the picture tube socket board, adjust the 

horizontal lines for maximum sharpness. 

- Afterwards, adjust the vertical lines with the focus control on the 

focusing board for maximum sharpness. 

- Repeat this adjustment to achieve the best result possible.

No sound after the receiver has been operated in standby mode for a 

prolonged period of time. The sound is audible again only on disconnecting 

the mains plug and switching the satellite receiver on again. 

Reason: 

As advised by our Service Information 4/97, this phenomenon is caused by 

IC STV 400 STV 0056A but cannot be limited to certain IC lots. 

Cure: 

Solder one SMD Z-diode 8.2V each in parallel with the electrolytic 

capacitors C 427 (pin 49 IC400) and C 436 (pin 38 IC400) which are 

connected to chassis.

Risks of failure of electric connections (solder pads) caused by ageing 

For reasons of thermal load and mechanical stress solder pads at positions 

where high voltages and /or currents are effective involve special technical 

problems. 

In this connection we would like to refer you to our Service Information 

bulletin „General 1/95“ which dealt in great detail with this subject. 

Solder pads which should be checked with special care in every set coming 

in for repair are for example: 

- within the line output stage, the connections of line and diode split 

transformers, connecting pins of the yoke plug, components of the +A 

supply rail as well as the capacitors and coils within the deflection circuit. 

- within the mains supply stage, the transformer connections, the 

connections of the rectifier and charging capacitor as well as the 

connections of the stabilizing ICs.

Product Colour television receivers with chassis CUC 63xx, 64xx, 20xx and Digi Basic/ 

Digi 6 - new plug-in systems 

The television receivers with above mentioned chassis are partly 

fitted with new plug-in systems between the modules and the chassis. 

As a consequence of this conversion, the modules with the new systems 

can no longer be pulled out of the chassis as usual. When trying to do 

so damages may be caused to the module or the chassis. 

The following figures show the different systems and how they can be 

dismounted. 

1. The traditional black socket terminal 

strips of the modules are additionally 

provided with locking lugs which, in 

addition to a module holder, prevent 

the module from slipping out. The 

module can be dismounted from above 

or below by pressing the locking lugs 

together. 

Fig. 1 

2. The modules of the colour television receivers with chassis CUC 20xx 

are fitted with a new plug-in system. They can be dismounted by 

disengaging the locking lug with a screw driver. In future, it will also be 

possible to release the lugs from below through additional drilled 

holes in the chassis. 

Fig. 2 

3. Concerning the Feature Boxes on the Digi Basic and Digi 6 chassis: 

Please note that in contrast to our earlier Digi chassis (Digi 3, 4 and 5) 

the two earth lugs of the Box for interference protection are 

soldered in. In the case of any defect, these lugs must be 

unsoldered!

Programme position number (e.g. „P 14“) is continuously displayed on the 

screen. 

Reason: 

When having pressed the „i“ button on the remote control handset no 

further command is entered during a period of about 6 seconds. As a result, 

the TV set switches over to the continuous display mode so that the 

programme position number is continuously visible on the screen. As this 

function is not mentioned in the product descriptions, it may happen in a 

few cases that consumers think it to be a fault. 

Cure:

Cure: 

The interference level can be reduced noticeably by soldering in an 

additional ground-to-ground connection. 

Workshop: 

Solder an insulated wire of approx. 35mm (2.5mm 2 ) in length on to the 

solder side of the mains supply section (between pos. R60007 and C60001) 

as shown below. This additional wire is used to short-circuit the ground loop

Moiré patterning / interferences similar to pearl strings visible in the picture 

of stations in the lower special channels (S05, S06, S07). 

Reason: 

Harmonics from the switched mode power supply entering via insufficiently 

screened or defective aerial connecting cables. 

Cure: 

Use an aerial cable with double screening! In special cases, an absorber 

cable („100 Hz aerial connecting cable), order number 29210 435 0100, may 

be necessary. 

If the fault is not yet completely eliminated, carry out the following changes 

in the circuit: 

1. Solder the „hot“ contact of the capacitor C 60009 (220pF/2kV) 

directly to pin 1 of the transformer TR 61001. 

2. Connect the earthing area on the upper side (component side) within 

the power supply section with the earth tag on the solder side. 

For this solder a short piece of wire to the earth connection of R 60014 

(not fitted) and contact it with the earthing area on the upper side. To 

ensure that the wire is reliably in contact with the earth, remove the 

solder resist and bend the wire down by a length of about 5mm. 

Workshop: 

To connect the capacitor C 60009 directly to pin 1 of the transformer 

TR 61001 proceed as follows: 

- Interrupt the circuit path between C 60009 and L 60006. 

- Fit the wire bridge „BR 145“. It is located between C 60009 and L 60006 

(sometimes also designated „BR 6008) and connect the separated end of 

the capacitor with the bridge (bend the connecting wire of the bridge 

towards the capacitor). 

Carry out these changes with extreme care (VDE safety regulations)!

Product Defective modules returned for repair within our repair exchange system 

A relatively great number of the defective modules coming in for repair is 

returned without the fault tag! 

This makes work more difficult for us because the defect complained of 

could be a hidden fault that shows only occasionally. Please help us 

discovering hidden faults by sending in the defective module together with 

the fault tag. A fault tag is enclosed with each replacement module. 

In this connection we want to point out to the observance of the generally 

known MOS safety instructions („Safety“ Service Manual). 

These instructions apply also to the handling of defective modules. 

- When returning defective modules please use generally the MOS 

protective packing enclosed with the replacement module. 

- Even defective MOS components must never be stored or transported in 

styroper material or in plastic magazines. 

- Persons handling MOS components must first discharge any electrostatic 

charge on their body or clothing by touching a grounded object.

From September 1998 onwards, colour television receivers with the CUC 

7303 chassis have been fitted with a reworked chassis CUC 7303. It is 

provided with a new processor and a few changes were made in the 

peripheral circuit of the computer. 

The television receivers with the reworked chassis are marked with a 

Version Number „VN...“ printed on the label on the back of the receiver (see 

figure).

From now on, the SER 150 ET Retrofit Kit will be delivered without the EPROMs previously 

enclosed with the delivery for TV sets with Digi 6 and Digi Basic TV chassis. 

The TV sets have already been provided with a software covering all the functions of the 

SER 150 ET since 4/97. As a result, the EPROM of the currently delivered TV sets needs 

not to be exchanged. Should you receive a TV set manufactured before 1997 for 

retrofitting, check the software version (call up the version pressing the buttons „i“ -> „OK“ - 

> „AUX“). If the version for the chassis: 

CUC 1805, 1825, 1826 and 1827 (Digi Basic) is lower than 19798-300.20, and for the 

chassis Digi 6 CUC 1842, 1894, 1984, 1952 and 1983 is lower than 19798-311.20, the 

EPROM needs to be replaced. The EPROM of TV sets with Digi Basic++ needs not to be 

replaced. 

The required IC is available from the Central After-Sales Service under part number 19798

No operation - failure of the switched mode power supply (transistor / drive-IC / other 

components). 

Cause: 

Due to tolerances of the mains transformer 29201 513 9700 the collector current of 

transistor T 665 (MJF 1800) may reach limit values and consequently cause the power 

supply to fail. 

Cure: 

On replacement of the defective components change additionally the resistor R 666 from 

0.82 Ohm to 0.91 Ohm. As a result limitation of the collector current is activated earlier so 

that the limit values will not be exceeded.

Failure of vertical output IC TDA 3653. 

Reason: 

Static discharges to the deflection windings. 

Cure: 

1. For protecting the IC, change the capacitor C422 from 47nF to 0.1µF/100V. 

Note: This 47nF capacitor is not inserted in all television receivers with 37cm 

Philips picture tube. However the circuit board is prepared for later insertion of 

this capacitor. 

2. Solder an additional diode BAV 21 on to the foil side from the negative 

terminal of the electrolytic capacitor C412 to pin 5 (cathode to pin 5) of the

A short time after switching on (about 20-30 sec.) the TV set cannot be 

operated any more. 

Cause: 

Unfavourable constellation of the received station identifications. 

Remedy: 

Software change to version „18“ by replacing the EPROMS IC 80070. 

Workshop: 

On every incoming repair set with a software version below „18“ replace the 

Eproms with one of the new version. 

The software version of the TV set can be called up via the „Dialogcenter“ 

(button „i“ -> „OK“) by pressing the „AUX“ button. In doing this, the indication 

29798-101.xx (the „xx“ positions indicate the software version) appears at the 

top border of the picture screen. 

If the software is updated from a version below „14“ to „18“, the following 

points must be observed in addition: 

1. After changing the software carry out an ATS reset. This is done by 

switching on with the mains button with the L+ button held down (L+ 

button on the TV set!). Keep pressed the L+ button until the „ATS Rest“ 

window appears in the picture. When switching the TV set on the next 

time, the set will prompt for entering the OSD language and the country. 

Then it will start a new station search. Do not abort the station search! 

2. Check and correct if necessary via the protected menu for the specialized 

dealer (code „8500“) under menu item „Picture tube type“ the current 

setting. The table below shows the setting depending on the picture tube:

The set shows a brief flashing before the Eco switch unlocks. 

Cause: 

Through the attraction of the Eco switch the stanby power supply unit is charged 

too highly and causes a reset of the processor module. This reset in turn causes 

briefly before the release of the Eco switch a temporary rise of the operating 

voltages and thus a brief flashing of the picture tube (brief building up of the 

high tension).

After fitting the satellite retrofit kit SER 251, no satellite reception is possible. 

Cause: 

Contrary to brochure statements, these TV sets have been manufactured 

without retrofit option.

1. Remove the chip resistances CR 32131 and CR 32129. 

2. Fit the following components:

Possible complaints: 

The eco switch does not release. 

Cause: 

Through the attraction of the eco switch the standby power supply undergoes 

a too high load and causes a reset of the processor unit. This reset causes 

just before the attraction of the eco switch a brief rise of the operating voltage 

and may therefore prevent the release of the eco switch. 

Remedy: 

Replace the standby transformator with the version 29201 619 9700. In 

addition, the complete standby power supply unit can be replaced with the 

version 29304 050 8500 on the chassis Basic 3.

Flash programming for the new Digi 100 generation 

For the above stated series of sets, no completely programmed EPROM has 

been used for the device software. The software is stored in a Flash-Eprom that 

can be externally loaded. In this way it is possible to update the software without 

opening the housing of the TV set. 

To do this, the new software is downloaded into the TV set via the serial interface 

of a PC and the programming socket located at the rear of the TV set using

Setting hints and special functions (options) for the colour TV sets with 

the chassis Digi 100 (CUC 1807, 1837, 1838, 1839, 1934, 1935) 

e.g.: Elegance 70 M 70-300 Dolby, Elegance 70 MW 70-150/8 Dolby, 

Hamburg SE 8240 Dolby, M84-212/8 Dolby, Toronto SE 7216 Dolby 

Below you find setting hints and explanations for various functions of the TV 

sets with the chassis Digi 100. 

1. Power-on behaviour of the set 

In the „Special functions“ menu you can select under the „Power on“ menu 

item between „automatic“ and „Programme position 1“ . 

automatic: the set is switched on with the last power-on mode. For this, the 

last recognized programme position and operating mode (standby or 

normal operating mode) are stored. 

Note: if the set has been switched off with the mains button in standby 

mode, it goes again in standby mode after power on and must 

definitely be switched on using the remote control. 

Programme position 1: the set selects programme position 1 each time it is 

switched on. 

2. Settings in the „Programme table“ menu 

In this menu, further presettings can be programmed in addition to the 

channel setting for every programme position. 

Note: direct channel entry is only possible in the programme table. 

„P+“ reversion point: the reversion point is the limitation of the programme 

positions for programme selection using the „P+“ button. This 

reversion point is marked with an orange line in the programme table. 

To shift the reversion point, it is necessary to shift the programme 

position above or below this line according to the direction of shift. 

1-/2-/3- digit programme position selection (3-digit only with a retrofitted 

satellite module): for 1-digit programme position selection you must 

place the reversion point in the programme table between the 

programme positions 1 and 10. For 2-digit programme position 

selection place the reversion point between the positions 10 and 100. 

Forced settings (forced colour standard, forced mono, fixed assignment of a 

multi-channel sound, RF time constant, AFC): 

In the „Channel settings“ menu (menu guide: „i“ -> „Programme table“ 

-> „Edit“ -> „Change channel settings“) you can carry out various 

forced settings. 

Note: it is also possible to set a forced colour standard for the AV 

programme positions in this menu.

3. Volume adjustment: 

You can store a volume setting deviating from the basic volume separately for every 

programme position in the „Sound“ menu (blue button) under the menu item „Volume 

adjustment“. This adjustment is allowed by the software only if the basic volume is higher than 

7 of the 64 steps of the control range. 

4. Picture settings (brightness, contrast, colour, etc.): 

The desired picture settings are carried out in the „Picture“ menu (red button). Changing the 

contrast is only possible with the „manual“ presetting. The presettings „During the day“ and „In 

the evening“ are stored with fixed contrast settings. To get a better overview, it is possible to 

reduce the large menu scale after selecting the desired menu item by pressing the „OK“ 

button. In doing so, more menu content is visible and the setting, e.g. colour contrast, is highly 

facilitated. 

5. Sat radio (only with satellite retrofit kit SER 300A): 

Via the menu guide „i“ -> „Infothek“ -> „Sat-Radio“, about 40 pre-stored sat radio stations can 

be called up (dark picture screen, only the station name is visible). In this operating mode, the 

programme table can be displayed after pressing the „i“ button in order to select/change the 

sat radio stations. 

6. Time and date: 

Each time the set is powered on, the internal software clock is set when receiving a station 

broadcasting Teletext. 

If only stations without Teletext are received after power on, no clock time can be called up. In 

this case, the clock and time can manually be set via „i“ -> „Installation“ -> „Time and date“. 

7. AV settings: 

The sets with the chassis Digi 100 provide the possibility of individually configuring all 

available AV programme positions. The factory settings are: 

AV 1 for the connection of a Megalogic video recorder, 

AV 2 for the connection of a DVD player (via RGB), 

AV 3 (if available) for the connection of a VHS video recorder (a switching voltage is 

necessary at the Euro-AV socket Pin 8), 

AV 4 for the connection of a VHS camera. 

If you wish to change these presettings, you can individually configure all AV connections via 

„i“ -> „Installation“ -> „Connections“ . In this menu, various units are preset which can be 

activated if they are required. A connection diagram can be displayed by pressing the yellow 

button. 

In addition own unit profiles can be created via the menu item „Manual AV settings“. These 

unit profiles are indicated with „manual“ in the connection diagram. Please note that settings in 

the „Manual AV settings“ must correctly be effected in any case, and that preset units at AV 1, 

AV 2 etc. are deactivated at the same time (see connection diagram). For example, an 

incorrectly set time constant would result in a black/white picture with a VCR signal source.

Additional function through software change (version 1.1) 

After replacing the Feature module, the unit-specific settings like colour 

registration, noise reduction, picture sharpness, white balance, CRT type, PIP 

position, picture geometry, and the customer-specific programme data must be 

set up. 

The extension of the FProg1 software now makes it possible to read out this data 

and to write it into the new module. 

This means a considerable decrease of expenditure of work. 

For reading out and programming the operating software and the unit-specific data 

you need the Flashprogrammer FProg1, part no. 759880740000. Please consult for 

this also the Service Information ”General, serial no. 01/01“. 

The Flash-Programmer comes with the software version 1.0. Please load the current 

software, version 1.1, directly from the Internet (see Online Service brochure). This 

is to be found under “Reseller Support“, “Software Download“ in the category 

”Programming software“, Product group ”DIGI 100”. The updated description of 

the FProg1, V1.1 software is to be found under Advice ”Operating instructions Flash- 

Programmer F-Prog1“.

TV sets with Digi 100 chassis 


The TV set switches at times to standby and then after several seconds back to normal 

operation. 

Cause: 

This failure may be caused by an uncontrolled oscillation of the CVBS input and a faulty 

software library of the processor. 

Remedy: 

To eliminate this failure it is generally necessary to update the unit‘s software. For this 

consult the table 1 (software assignment). 

- Update the operating software of the TV set. The software required can be downloaded 

from the Internet. 

For this consult also the Service Informationen ”General 01/01“ and ”TV 04/01“ 

(external). 

In addition it is necessary to check and change if necessary the circuit of the 

Feature module of older TV sets. TV sets and chassis which do not require a change of 

the circuit are listed in the tables 2 and 3. The positions of the serial numbers of the TV 

sets and chassis are described on page 4. 

For the positions of the components concerned on the Feature module please see the 

circuit diagram excerpt and the PCB illustrations on page 2. 

- Remove the chip capacitor CC80209 (coordinates x71/y78) if provided. 

- Connect CIC80000, Pin 117 with ground (e.g. chip capacitor CC80205 (coordinates 

x71/y81), replace with a chip jumper, or solder in a wire bridge from Pin 117 to 

ground).
