GB 3A10E-DPL2.
2.1Safety instructions for repairs
Safety regulations require that during a repair:
•Safety components, indicated by the symbol
be replaced by components identical to the original ones;
•When replacing the CRT, safety goggles must be worn.
Safety regulations require that after a repair, the set must be
returned in its original condition. In particular attention should
be paid to the following points:
•General repair instruction: as a strict precaution, we
advise you to resolder the solder joints, through which
the horizontal deflection current is flowing, in particular:
– All pins of the line output transformer (LOT);
– Fly-back capacitor(s);
– S-correction capacitor(s);
– Line output transistor;
– Pins of the connector with wires to the deflection coil;
– Other components through which the deflection
current flows.
Note: This resoldering is advised to prevent bad connections
due to metal fatigue in solder joints and is therefore only
necessary for television sets older than 2 years.
•The wire trees and EHT cable should be routed correctly
and fixed with the mounted cable clamps.
•The insulation of the mains lead should be checked for
external damage.
•The mains lead strain relief should be checked for its
function in order to avoid touching the CRT, hot
components or heat sinks.
•The electrical DC resistance between the mains plug and
the secondary side should be checked (only for sets
which have a mains isolated power supply). This check
can be done as follows:
– Unplug the mains cord and connect a wire between
the two pins of the mains plug;
– Set the mains switch to the 'ON' position (keep the
mains cord unplugged!);
– Measure the resistance value between the pins of
the mains plug and the metal shielding of the tuner or
the aerial connection on the set. The reading should
be between 4.5 MΩ and 12 MΩ.
– Switch off the TV and remove the wire between the
two pins of the mains plug.
•The cabinet should be checked for defects to avoid
touching of any inner parts by the customer.

2.3Warnings
•In order to prevent damage to IC's and transistors, all
high-voltage flashovers must be avoided. In order to
prevent damage to the picture tube, the method shown in
Fig. 2-1 should be used 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. 30 s).
V
Figure 2-1
•All IC's and many other semiconductors are susceptible
to electrostatic discharges (ESD)
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. Keep components and tools also at this same
potential. Available ESD protection equipment:
– Complete kit ESD3 (small table mat, wristband,
connection box, extension cable and earth cable)
4822 310 10671.
– Wristband tester 4822 344 13999.
•Together with the deflection unit and any multipole unit,
the used flat square picture tubes form an integrated unit.
The deflection and the multipole 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 making settings, use plastic rather than metal
tools. This will prevent any short circuits and the danger
of a circuit becoming unstable.

It is recommended to have a maintenance inspection carried
out by a qualified service employee. 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 3
to 5 years.
•When the set is used in circumstances with higher dust,
grease or moisture levels, for example in a kitchen, the
recommended interval is 1 year.
•The maintenance inspection contains the following
actions:
– Execute the above-mentioned 'general repair
instruction'.
– Clean the power supply and deflection circuitry on
the chassis.
– Clean the picture tube panel and the neck of the
picture tube.

Amplifier - Power supply circuit description
(W1,W2,W3,W4)
Amplifier
The used amplifier TDA2616Q is a stereo power amp with
voltage gain of 30dB, which can deliver 2 x 10 Watts into 8 Ω
load. The amplifier is powered by a symmetrical power
supply; therefore no output capacitors are needed. A socalled Boucherot network (R3453, C2433 and R3452,
C2434) is placed on both outputs. The measured output
voltage varies between +/- 14.5 Vdc and 19 Vdc; this
depends on the delivered output power in both speakers (at
nominal mains voltage).
IC7402 and all passive components around this part form a
highpass filter (-3 dB 120 Hz); this filter is implemented
because the used box and speaker are not intended to
reproduce low frequencies. A pre-amp (IC7403) gives an
additional 6 dB gain to give the whole system the correct
sensitivity. The preamplifier and filter part work on a
symmetrical power supply +9 and -9 Vdc. This +/-9 Vdc is
derived from the main supply by use of zenerdiodes 6402 &
6401; resistors 3401-3404 and capacitors 2403 & 2402.
Mute-standby
To ensure plop-free operation, some additional circuits were
required. The power amp can be muted in 3 different ways by
transistor 7415.
1. At power-on: the circuit around 7416 gives a delay at startup, to allow the power supplies to be stable.
2. At power-down: In normal operation, transistor 7417 is on,
7415 is off and the amplifier 7401 is enabled. At power-down
the transistor 7417 is switched off fast, 7415 is on, and the
amplifier is muted before the power supplies become
instable.
3. Mute from the receiver: When there are perturbations and
/ or interferences during the transmission, the mute-output
line of the receiver becomes high (4 Vdc) and switches on
transistor 7415, which will mute the output amplifier.
When the transmission of surround signals is ended (e.g.
television off) the mute line from the receiver becomes high
and mutes the amplifier via 7415. The red LED indicates this
condition via 7413, 7414 and 7411. The green LED is on
when the mute line (connector 1401 - pin 1) is low, thus
indicating that the box is really receiving. The power
consumption during "muted-standby" condition is about 6.5
Watt @240 Vac, mainly caused by the receiver, who stays
active with the supply delivered by 6405, 6406 and 7201
(L7812 regulator, W2)
Transmitter
The television set takes full control over the transmitter via a
5- and 1-pin connector. The TV provides the DC power (and
power ground), pilot mute, I2C enable, SCL and SDA I2C
lines. The left and right audio signals, with signal ground, are
accepted via a 3-fold, shielded cable. The transmitter is
equipped with an always-enabled compander function to
lower the noise-floor needed for Dolby surround-sound
applications. The audio sensitivity is fixed and set to 0.3 Vrms
nominal input level.
For the 864 MHz versions there is a built in limiter to limit the
RF bandwidth. The limiter starts to limit at nominal input level
+ 6 dB, or 0.6 Vrms, the maximal input level. The RF power
is radiated by means of an integral λ/4 antenna. The RF
signal is a wideband FM modulated carrier. Maximal
deviation is set to 50 kHz. The modulating signal is a Zenithlike stereo multiplex signal with 1 surround (20 Hz to 10 kHz)
audio channel. The composite signal is referred to as 85%
LR + 15% pilot (42.5 kHz baseband + 7.5 kHz pilot) for this
50 kHz system. The power is drawn from within the TV set
(14 V-150 mA). Minimum voltage 11.0 V (including ripple)
and maximum voltage is 16 V.
Receiver
The receiver is a one-channel version (mono), from which
only the surround channel output is made available. The
receiver always accepts channels up to 20 kHz bandwidth.
The stereo Pilot-Detect (PD) or ‘MPX VCO lock’ information
is usually combined with the Search-Detect (SD) or ‘RF field
strength threshold’ to produce the audio mute signal. This
signal is used to drive the internal mute circuitry. It is also
made available as an output to switch the application in sleep
mode or just mute the power amplifier.
The DC supply voltage is drawn from within the application
rated at 12 V-150 mA. The minimum voltage, including ripple,
is 9 Vdc. The maximum allowable ripple on the supply line is
25 mV peak.
The receiver accepts a FM signal, modulated with the
enhanced 70 kHz wide stereo MPX baseband signal. For 864
MHz systems the maximum deviation of the FM signal is
expected to be 50 kHz. The receiver sensitivity (or SD
threshold) is set to 5 µV over 50 Ω.
A 7-position slide switch is used to select the RF carrier
frequency. Channels 1 through 7 are selected from left to
right. The frequency grid is 250 kHz and uses the same
channels as by the transmitter (see table 9-1). The enhanced
multiplex (MPX) or composite signal is referred to as 85% LR
+ 15% pilot (42.5 kHz baseband + 7.5 kHz pilot) for the 50
kHz systems (864 MHz versions).
