The bridge coil L511 is correctly adjusted during

production and should not be re-adjusted any

more.

Call up the Service Programme > Info Centre

> Special Functions > Service > Code

Number 8500 > Geometry.

Set the horizontal amplitude to minimum.

Connect channel of an oscilloscope one to the

collector of the transistor T568.

Connect channel 2 of an oscilloscope between

the diodes D502 and D503.

Alignment Process

Adjust the coil L511 so that both oscillogramshave the same pulse width.

Re-adjust the horizontal amplitude to the test

pattern and store.

Line sharpness

Preparation

Select the convergence test pattern.

Contrast to maximum.

Set the brightness so that the black background

of the test pattern is just brightening.

Alignment Process

With the focus control adjust the horizontal lines

for maximum sharpness.

1.5: Alignment

Tuner AGC

Preparation

Feed in a standard test pattern in the upper

range of the UHF band; the RF must be 1.5V

(64dBmV, noise free picture) at least.

Info Centre > Special Functions > Service

> Code 8500 > Tuner AGC.

Alignment Process

With the buttons and tune the TV station

so that noise just starts to appear in the picture.

Then tune in reverse direction until the picture

just becomes noise free. Store with OK.

1.5: Alignment

Preparation

Tune to a local station on a channel as low as

possible at the desired programme position with

standard channel spacing without fine tuning.


> Code 8500 > AFC-Reference.

Alignment Process

With the buttons tune the TV station so

that noise just starts to appear in the picture.

Then tune in reverse direction until the picture

just becomes noise free. Store with OK.

1.6: Alignment

Colour match

Preparation

Call up the programme position of the desired

TV station.

Info Centre > Special Functions > Settings

> Colour Match.

Adjust with and buttons to make the

signals coincide. Store with OK.

1.7: Alignment

White balance

Preparation

Call up the White Balance menu via the Service

Programme Info Centre > Special Functions

> Service > Code Number 8500.

Alignment Process

With and buttons set the VG and VB

values so that the white rectangular area in the

middle of the picture becomes achromatic.

Store with OK.

Alignment Process

Change the value with the buttons.

1.9: Alignment

Picture geometry

Preparation


> Code 8500 > Geometry.

For accurate adjustment of the picture a test

generator or a standard test pattern should be

used. The integrated test pattern or grid pattern

may also be used.

Attention:start always with the V-Middle

adjustment otherwise the other vertical deflec-

tion parameters would defy correct geometry

adjustment.

V-Middle adjustment with a video generator,

eg. Grundig VG1000.

Reset: Under the menu item Reset an average

data set from the ROM IC820 is stored. After

inadvertent re-adjustment during servicing,

these basic values can be re-loaded at any time.

Alignment Process

Via the menu, select the geometry values for the

vertical deflection, then set the values for the

horizontal deflection.

With the or buttons change the setting so

that the G-Y vector (orange area in the centre of

the picture) is just covered (typ. 30 ... 33).

Continue with the picture geometry adjustment

via the menu and store.

Reset: for this, move the bar to Reset. Press

the OK button.

With the ibutton return to the normal menu.

Video level

Preparation

Switch the SAT receiver to SAT reception (eg.

Astra) and set the correct video deviation (Astra

16MHz). Connect the test probe of an oscillo-

scope to the EURO-AV-socket, contact 19 (75W

termination).

Trigger the CCVS signal to the vertical sync

frequence.

Alignment Process

With adjustment control R3848 set the ampli-

tude of the vertical blanking gap in the CCVS

signal to 1Vpp.
