FOCUS
Adjust FOCUS VR for best overall definition and picture
detail at normal brightness and contrast.
NOISE (RF A.G.C. Delay)
This control is set at the factory and rarely requires any
adjustment. If a snowy picture appears on a medium to
weak station, adjust the NOISE VR.
1. Turn NOISE VR _ fully counter-clockwise, maximum
noise in picture.
2. Slowly turn NOISE VR clockwise until snow or noise
in picture just disappears.
Note: Check operation on strong channels. If over-
loading occurs (bending, poor colour, loss of
colour sync. etc.) make compromise adjustment.
VERTICAL HEIGHT
Adjust the V. HEIGHT VR to obtain the optimum size
of vertical height.
SUB BRIGHT AND SUB CONTRAST
1. Set the BRIGHT and PICTURE VR knobs to central
position respectively.
2. Adjust the SUB BRIGHT VR and the SUB CONTRAST
VR until an ideal picture is obtained.
SUB COLOUR
J. Receive a SECAM colour signal.
2. Adjust the COLOUR VR knob to obtain natural colour
density.
3. Adjust the SUB COLOUR VR until natural colour
density is obtained.
4. Receive a PAL colour signal.
5. Adjust the PAL SUB COLOUR VR until natural colour
density is obtained.
CHROMA CIRCUIT
@ PAL
DL-MATRIX
. Receive a PAL colour bar signal.
2. Connect an oscilloscope to pin of IC201 through
C307.
3. Adjust T302P for the maximize waveform (Burst signal).
4. Set the oscilloscope at_the X-Y mode and connect
channel 1 (X axis) to @ pin of 1C301 and channel 2
(Y axis) to © pin of 1C301 respectively.
5. Short TP-43A and TP-43B with a jump wire.
6. Supply bias to TP-40 through 10kQ resistor from
12V DC.
7, Adjust DL. AMP. VR so that the figure becomes (B)
from (A).
8. Adjust DL P. TRANSF (T303) so that the figure be-
comes (C) from (B).
9. While observing the screen, adjust colour synchroniza-
tion by manipulating the C312 (4.43 MHz OSC).

m SECAM
* Do the SECAM adjustment before the PAL adjustment.
. Receive a SECAM colour bar signal.
. Connect an oscilloscope to @) pin of IC301.
. Adjust BELL TRANSF. (T301S) for the flat waveform
as shown in Fig. 6-9-(B).
4, Connect a digital voltmeter to pin @8) of 1C301.
5. Adjust IDENT TRANSF (T302S) for the maximum
DC ovitage.
6. Adjust DISCRI. TRANSF. (T304) and DISCRI.
TRANSF. (T7305) until colours are eliminated from
the black-and-white sections of the colour bars.

HORIZONTAL WIDTH
Adjust H.WIDTH contro! coil by turning it with a
hexagonal adjusting bar only if RIGHT and LEFT sides
of pictures can’t be seen.
V. IF CIRCUIT
1. Connect a color bar generator to antenna terminal.
(When the signal is too strong, use the attenuator.)
2. Connect DC voltmeter (or tester) between AGC terminal
of E. Tuner and earth.
3. Rotate “Noise” volume (R109) so that RF. AGC voltage
becomes DC 4.5V +1V.
4. Adjust CW Transformer so that the indicator becomes
to minimum.
5. Confirm the adjustment of ‘‘Noise”’.
RF. AFC
1. Connect a colour bar generator to antenna terminal.
2. Adjust AFC Transformer so that the voltage of TP-16
becomes DC 6.5V +0.1V.
(Confirm to swing between about 9V and 4V previously.)
S. IF CIRCUIT
1, Tune in a local station preferably a program with the
continuous audio.
2. Adjust T601 and T602 so that the sound becomes to
maximum without distortion.
