SETUP PROCEDURE & ALIGNMENT INSTRUCTIONS

All necessary adjustments and settings are performed during manufacture of TV set and assure its
correct operation when connected to the mains voltage and antenna or external video or audio signal.
When TV set requires service intervention all settings should be checked and corrected, if necessary.

DEMAGNETISING OF PICTURE TUBE

Correctness of picture tube demagnetising is usually automatically checked. Magnetisation of picture
tube is presented as one or more colour "clouds", consequently colour reproduction of the picture is
not correct.
Each time the TV set is switched on with mains switch, demagnetising system is activated. For correct
demagnetising procedure disconnect the TV set with mains switch and leave it disconnected for about
15 minutes. Afterwards when yo u switch on the TV, demagnetising procedure is performed. In case
distortion of colour reproduction still persists, special demagnetising coil should be used.

ADJUSTMENT ADJUSTMENT

CONDITION

1. SUPPLY VOLTAGE
FOR HORIZONTAL
OUTPT STAGE

»B+«

• Connect the TV set to

supply voltage
175…250VAC.

• Switch it on and set it by

means of remote
controller to AV mode of
operation.

• Connect DC voltmeter to

D-602 cathode.

SWITCHING TO SER V ICE MODE

All other service settings of TV set are made in so called service mode of TV set operation. To enter this mode of operation press
the keys in the following sequence: "TV", "I", and "STOP" in the period of 5 seconds from switching on the TV set to normal mode
of operation. When the TV set is switched over to service mode the following status line with service parameter and parameter value
appears on the screen:

SERVICE PARAM: XX VALUE: xx

The parameter to be set is selected with keys (P+/P-), and selected parameter is set with keys (volume+ /volume-). Each
time you press the key for parameter selection ( ) the value of preselected parameter is stored. Therefore when the last setting is
performed you must press one of the two keys once again. Values of individual parameters are expressed in hexadecimal form due
to limited capacity of the memory. Values of individual parameters are variable from 0 to 3F, with the exception of some parameters
(see the table at the end of describi ng service mode) where values are changed from 0 to 7F and O1, O2, O3, O4, O5 which have
value range between 0 an d FF.
When setting is finished it should obligatory be concluded with "STOP" key. After a few seconds the status line disappears and
service adjustment is accomplished.

NOTE: In case service adjustment is not ended in above specified mode (e.g. power supply breakdown), the

adjustment should be repeated.

2. VERTICAL

• To antenna connector of

TV set, which is switched
on and operates in service
mode, connect VF signal

controller correct the
picture. The distances
between the two
horizontal lines of
test picture in the

Option bytes are set so that besides selected op tion byte also hexadecimal number is set on the basis of
above tables.

Example:

• blue back-enable

• dynamic skin control enable

• blue stretch enable

Select option byte O1 and for items, which should be activated, set “1” (other bites are “0”). In our case
is as follows:

O1:

7 6 5 4 3 2 1 0
0 0 0 1 1 0 1 0

1 A

Shaded binary number should now be converted to hexadecimal value (darker frame). Afterwards set
this value.

SERVICE PARAM: O1 VALUE: 1A

• CAUTION: Option bytes are Factory adjusted and must NOT be changed later, because

they change TV set characteristics.

Port 0 is an 8-bit open drain
bi-directional I/O port. Port 0 pins
that have 1s written to them
float; in this state they can be
used as high-impedance inputs
(e.g. for software driven
Bus).

Port 1 is an 8-bit bi-directional
multifunctional I/O port with
internal pull-up resistors.

Port 2 is a 4-bit input port without
pull-up resistors. Port 2 also
works as analogue input for the
4-channel-ADC.

Port 3 is an 8-bit bi-directional
I/O port with internal pull-up
resistors.

Port 4 is a bi-directional I/O
port
