WARNING

The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug
and power receptacle, when servicing this chassis.
To prevent electric shock, do not remove cover. No user-serviceable parts inside. Refer servicing to
qualified service personnel.

29LF-92E

Only qualified service personnel are allowed to carry out maintenance and repair of this receiver.

Servicing of High Voltage System and CRT

It is important that the static charge is removed from the high voltage system when carrying out work on the
receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT
cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the
receiver.

Note the following:

•

• If the CRT has to be changed it MUST be replaced with the correct type for continued safe working.

• DO NOT lift the CRT by its neck.

• When handing the CRT, ensure that shatterproof goggles are worn.

• Ensure that the CRT is discharge before handling.

IMPORTANT SERVICING NOTES

The CRT in this receiver employs Integral Implosion Protection.

X-Ray

This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions and
servicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when in
close proximity to the receiver for long periods of time. To reduce any risks associated with this, please
observe the following precautions:

1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 33 KV, (at a

instantaneous beam current of 1800 µA).

2. Ensure that during normal operation the EHT does not exceed 29.55 KV (at a beam current of 1800 µA).
This level has been preset in the factory. Always check that this level has not been exceeded after
carrying out any repair on the receiver.

3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may cause
excessive x-ray radiation.

Before returning the receiver to the customer

In addition to the above checks, the following should also be carried out before returning the receiver to the
customer.

1. Inspect all the leads to ensure that they are dressed correctly and that they are not obstructed or pinched
by any other parts.

2. Ensure that all protective devices are in good condition. These will include nonmetallic control knobs,
insulating fish papers, cabinets backs, compartment covers or shields, mechanical insulators, etc.

4.VIDEO SWITCH TEA6415

In case of three or more external sources are used, the video switch IC TEA6415 is used. The main
function of this device is to switch 8 video-input sources on the 6 outputs.
Each output can be switched on only one of each input. On each input an alignment of the lowest level
of the signal is made (bottom of sync. top for CVBS or black level for RGB signals).
Each nominal gain between any input and output is 6.5dB.For D2MAC or Chroma signal the alignment
is switched off by forcing, with an external resistor bridge, 5VDC on the input. Each input can be used
as a normal input or as a MAC or Chroma input (with external Resistor Bridge). All the switching
possibilities are changed through the BUS. Driving 75ohm load needs an external resistor. It is possible
to have the same input connected to several outputs.

5.MULTI STANDARD SOUND PROCESSOR

The MSP 34x10G family of single-chip Multi-standard Sound Processors covers the sound processing
of all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip.
The DBX noise reduction, or alternatively, MICRONAS Noise Reduction (MNR) is performed alignment
free. Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM
Stereo Radio standard.

9.POWER SUPPLY (SMPS)

The DC voltages required at various parts of the chassis are provided by an SMPS transformer
controlled by the IC MC44608, which is designed for driving, controlling and protecting switching
transistor of SMPS. The transformer generates 145V for FBT input, +/-14V for audio amplifier, 5V and

3.3V stand by voltage and 8V, 12V and 5V supplies for other different parts of the chassis.
An optocoupler is used to control the regulation of line voltage and stand-by power consumption. There
is a regulation circuit in secondary side. This circuit produces a control voltage according to the
changes in 145V DC voltage, via an optocoupler (TCET1102G) to pin3 of the IC.
During the switch on period of the transistor, energy is stored in the transformer. During the switch off
period energy is fed to the load via secondary winding. By varying switch-on time of the power
transistor, it controls each portion of energy transferred to the second side such that the output voltage
remains nearly independent of load variations.

13.6.STV9379FA

13.6.1.Description

Designed for monitors and high performance TVs, the STV9379FA vertical deflection booster can
handle flyback voltage up to 90V. Further to this, it is possible to have a flyback voltage, which is more
than the double of the supply (Pin 2). This allows to decrease the power consumption, or to decrease
the flyback time for a given supply voltage. The STV9379FA operates with supplies up to 42V and
provides up to 2.6APP output current to drive the yoke. The STV9379FA is offered in HEPTAWATT
package.

13.8.1.Description

The L7800 series of three-terminal positive regulators is available in TO-220 TO-220FP TO-3 and D 2
PAK packages and several fixed output voltages, making it useful in a wide range of applications.
These regulators can provide local on-card regulation, eliminating the distribution problems associated
with single point regulation. Each type employs internal current limiting, thermal shutdown and safe
area protection, making it essentially indestructible. If adequate heat sinking is provided, they can
deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices
can be used with external components to obtain adjustable voltages and currents.
