2. Safety & Maintenance Instructions, Warnings and Notes
2.1 Safety Instructions For Repairs
2.2 Maintenance Instructions
Safety regulations require that during a repair:
--Due to the 'hot' parts of this chassis, the set must be connected to the AC power via an
isolation transformer.
-- Safety components, indicated by the symbol _, should 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. Pay 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:
--- 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 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 AC powercord for external damage.
-- Check the strain relief of the ACpower 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). Do this as follows:
1. Unplug the AC power cord and connect a wire between the two pins of the AC plug.
2. Turn on the main power switch (keep the AC power cord unplugged!).
3. Measure the resistance value between the pins of the AC plugand the metal shielding of the
tuner or the aerial connection of the set. The reading should be between 4.5 M and 12 M .
4. Switch the TV OFF and remove the wire between the two pins of the AC plug.
Check the cabinet for defects, to prevent the possibility of the customer touching any
Internal parts.
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 hree 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.
Colour Television Chassis: M123A
4

--- 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 multi-meter (position VDC). Discharge until the meter
reading is 0 V (after approx. 30 s).
---- AllICs 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.
Keep components and tools also at this potential. Available ESD protection equipment:
--- Complete kit ESD3 (small tablemat, wristband, connection box, extension cable, and ground
cable)
--- Wristband tester
--- 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.
--- 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 (see chapter 5) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless
stated otherwise) and picture carrier at 475.25 MHz (PAL) or 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 indicated by means of the appropriate symbols.
---- The picture tube panel has printed spark gaps. Each spark gap is connected between an
electrode of the picture tube and the Aquadagcoating.
--- The semiconductors indicated in the circuit diagram and in the parts lists are completely
interchangeable per position with the semiconductors in the unit, irrespective of the type
Indication on these semiconductors.

The cable TV signal into your home
may be a single cable (75ohm) or may
include a cable Box. In either case, the
connection to the TV is easy.
If your Cable TV signal comes
directly via a 75ohm coaxial cable,
use the following steps:
Connect the Cable TV signal to
the 75 OHM ANTENNA INPUT jack
on the rear of the TV. Screw it
Plug the TV s power cord into a

Set TV/CATV to CATV as detailed in
page11.
Refer to AUTO SEARCH to set up
your available channels. Details
are on page 12.
If you have a Cable Box, use the
following steps.
Connect the Cable TV signal to
the IN jack on the Cable Box.
Connect the separate coaxial
cable to the OUT jack on the Cable
Box and to the 75 OHM ANTENNA
INPUT jack on the rear of the TV.
Plug the TV s power cord into a
power outlet and turn on the TV.
Set TV/CATV to CATV as detailed in
page11.
Set the TV to channel 3 or 4 (the
same as the Channel3/4 switch on
your Cable Box if applicable).

An RF coaxial cable (to
connect the Cable Box to
the TV) may be supplied
by the Cable TV company.
