Memory IC Replacement (Important Notice)
Fig 5.
Fig 2.
SIF Alignment

When you replace a memory IC (IC790), it is necessary to
initialise the IC as follows.
Initialisation of Memory IC
1: When you press and hold the Function button on the TV set
and then press the Recall button on the RC transmitter, the
following picture will appear on the screen. (fig. 6)
Fig 6.
2: Confirm SET number of all items is “0” by pressing the
Function button.
3: If it is not “0” change to “0” by the Level (+/-) button.
(Changing the SET number, automatically memorised).
4: Press the Recall button to return to normal TV mode.

Service Adjustments
Service Control Adjustment
B1 Power Supply Adjustment
1: Set VR351 to be mechanical centre before pressing the main
switch.
2: Tune the receiver to PAL circular pattern.
3: Set brightness and contrast controls to normal.
4: Connect digital voltmeter to R791 (VR351 side).
5: By using VR351, adjust voltage to 130 ± 0.5V (for 21’). By
using VR351, adjust voltage to 150 ± 0.5v (for 25” and 28”).
AFT Adjustment
1: Tune the receiver to the clearest station.
2: By using T121, adjust AFT to obtain best picture.
AGC Adjustment
Note: Do not attempt this adjustment with a weak signal.
1: Tune the receiver to the clearest station.
2: Set AGC VR (VR120) in direction which causes snow noise to
appear, then in the opposite direction until snow noise just
disappears.
Grey Scale Adjustment
(Screen VR Adjustment)
1: Tune the receiver to white pattern.
2: Set brightness control to display centre and contrast control to
normal.
3: Set SW220 to ‘SERVICE” position.
4: Set VR602 and VR61 2 to be mechanical centre.
5: Turn VR601, VR611 and VR621 fully counter-clockwise.
6: Set screen VR for one colour to be just visible.
(Bias VR Adjustment)
7: By using VR601, VR611 or VR621, adjust line until white.
8: Set SW220 to “NORMAL” position.
(Drive VR Adjustment)
9: By using VR602 and VR612, adjust white balance.
High Voltage and Width Adjustment (High Voltage Adjustment)
1: Tune the receiver to PAL circular pattern.
2: Set brightness and contrast controls to maximum.
3: Connect digital voltmeter to both terminals of R232 (left side)
(+)‘ and a high voltage meter to the CRT anode.
4: Confirm high voltage to be 25.0 ± 1 kV at beam current 1 .0,
and less than 28.0 kV at 0 beam current (for 21”). Confirm
high voltage to be 26.0 ± 1 kV at beam current 1.1 and less
than 29.0kV at 0 beam current (for 25” and 28”).
(H-Width Adjustment)
5: If H-width is too wide or narrow, connect or disconnect a lead
wire J150 (for 21”). Adjust VR462 to obtain proper H-width (for
25” and 28”).
6: Reconfirm high voltage.
H-Centre Adjustment
1: Tune the receiver to the circular pattern.
2: Adjust H-centre by using VR4O1.
V-Centre Adjustment
1: Tune the receiver to circular pattern.
2: Adjust V-centre by using 5W451.
V-Size Adjustment
1: Tune the receiver to the circular pattern.
2: Adjust V-size by using VR451.
Focus Adjustment
By using FOCUS VR, adjust focus control for good scanning
lines.
