Possible complaint:
No display illumination.
Reason:
Failure of La301, La302, La303 or La304.
Cure:
To extend the lifetime of the bulbs, replace the bridge JP626 by a 3.3Ω/
0.33W resistor and a diode 1 N 4002 connected in series. Connect the
anode of the diode to the emitter of Q531.
Afterwards, change the four bulbs La301, La302, La303 and La304.
This change was introduced in the factory from the serial numbers listed
below:
UMS11: serial number 25904
UMS12: serial number 21721
Workshop:
Carry out this change in all systems coming in for repair.

General
Possible complaint:
When fitting a Grundig car radio into a motor car manufactured by VW (car
models Golf and Passat from year of manufacture 4/98), the following fault
symptoms may appear dependent on the type of radio:
- The car battery is discharged by the car radio after the car has not been
driven for a prolonged time.
- A radio with the conventional on/off switch cannot be switched off.
- When switched off, the display of the radio remains illuminated and the
colour of the display may have changed.
Reason:
VW company have changed the pinning of the car‘s ISO power supply
connector for the car radio. Contact 5 was previously provided for a positive
voltage switched by the car radio (for antenna/booster). From 4/98 models
onwards, an unswitched positive voltage may be applied to this contact.
Cure:
Please ensure that no unswitched positive voltage is applied to contact 5 of
the motor car otherwise remove the contact from the connector block and
insulate it appropriately.
Workshop:
Please note when fitting the car radio.

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.

Colour television receivers P 37-731 text and P 45-731 text with CUC 7303 text
Possible complaint:
Teletext information cannot be received via the Euro-AV connection, for
example when connecting a Grundig Micro-Sat Receiver.
Cure:
For activating the teletext mode in „AV“ progamme position retrofit the
following components:
- IC 2807 TEA 2114
- C 2815 1µF/100V
- C 2810 100µF/25V
- CC 2811 0.1µF
- CR 2814 390Ω 5% (structural shape 0805)
- CR 2813 change from 0Ω to 270Ω 5% (structural shape 1206)
- Solder a wire bridge BR 077 (+B‘ voltage to IC 2807 pin 7)
- Unsolder the electrolytic capacitor C 2816 and re-solder it to position
C 2817 (positive connection to pin 30 of processor IC 850).
- Remove the bridge BR 056.
Workshop:
The circuit board is already prepared for fitting the components.
The steps for retrofitting television receivers with chassis CUC 7301 are
described in our Service Information TV 3/97.
