Alignments
EN 54 L03.1U AA8.
8.3.2 TUNER
Note: Described alignments are only necessary when the NVM
(part reference number 7641) is replaced.
IFPLL
This adjustment is auto-aligned. Therefore, no action is
required (default= "30").
AGC (AGC take over point)
1. Connect the RF output of a video pattern generator to the
antenna input.
2. Input a color bar test pattern to the television set.
3. Set the amplitude of the video pattern generator to 10 mV
and set the frequency to 475.25 MHz (PAL/SECAM) or
61.25 MHz (NTSC).
4. Connect a DC multimeter to pin 1 of the tuner (item 1000
on the main chassis).
5. Activate SDAM by pressing the following key sequence on
the remote control transmitter: 0 6 2 5 9 6 directly followed
by the MENU button (do not allow the display to time out
between entries while keying the sequence).
6. Use the MENU UP/DOWN keys to highlight the TUNER
sub menu.
7. Press the MENU LEFT/RIGHT keys to enter the TUNER
sub menu.
8. Use the MENU UP/DOWN keys to select AGC.
9. Use the MENU LEFT/RIGHT keys to adjust the AGC value
(default value is "32") until the DC-voltage at pin 1 of the
tuner lies is 3.3 V.
10. Press the MENU button to return to the top level SDAM
menu.
11. To ensure the AGC change takes effect:
– Turn the television set 'off' by using the 'POWER'
button on the remote control transmitter or the local
keyboard.
– Disconnect the television set from AC power for at
least ten seconds.
