The table below lists the default GEOMETRY values for the
different television sets.
Table 8-3 Default geometry values
8.3.5 AUDIO
Necessary measuring equipment:
• MTS (Multi-channel Television Sound) generator (e.g.
Fluke 54200).
• AC millivolt meter.
ILA (Input Level Alignment)
1. 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).
2. Use the MENU UP/DOWN keys to highlight the AUDIO sub
menu.
3. Press the MENU LEFT/RIGHT keys to enter the AUDIO
sub menu.
4. Use the MENU UP/DOWN keys to select ILA.
5. Apply a BTSC sound signal with a signal strength of 60
dBuV (1 mV_rms) to the aerial input. Measure the output
on pin 16 (Main_outL) of IC7861 with an AC millivoltmeter
via a Low Pass Filter (R= 10 kohm, C= 1.5 nF, measure on
the capacitor).
6. Use the MENU LEFT/RIGHT keys to adjust the meter
reading to 106 mV_rms ± 2 mV_rms (default ILA value is
"31").
7. Press the MENU button to return to the top level SDAM
menu.
8. To ensure the ILA setting is saved:
– 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.
– Reconnect the television set to AC power.
– Turn the television set 'on' by using the 'POWER'
button on the remote control transmitter or the local
keyboard.
LSA (Low Separation Alignment)
1. 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).
2. Use the MENU UP/DOWN keys to highlight the AUDIO sub
menu.
3. Press the MENU LEFT/RIGHT keys to enter the AUDIO
sub menu.
4. Use the MENU UP/DOWN keys to select LSA.
5. Apply a 300 Hz BTSC sound signal with a signal strength
of 60 dBuV (1 mV_rms) to the aerial input (only the left
channel of the stereo signal). Measure the output on pin 22
(R_OUT) of IC7841 with an AC millivoltmeter.
6. Use the MENU LEFT/RIGHT keys to adjust the meter
reading to a minimum value (default LSA value is "7" for
stereo sets, and "0" for mono sets).
7. Press the MENU button to return to the top level SDAM
menu.
8. To ensure the LSA setting is saved:
– 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.
– Reconnect the television set to AC power.
– Turn the television set 'on' by using the 'POWER'
button on the remote control transmitter or the local
keyboard.
HSA (High Separation Alignment)
1. 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).
2. Use the MENU UP/DOWN keys to highlight the AUDIO sub
menu.
3. Press the MENU LEFT/RIGHT keys to enter the AUDIO
sub menu.
4. Use the MENU UP/DOWN keys to select HSA.
5. Apply a 3 kHz BTSC sound signal with a signal strength of
60 dBuV (1 mV_rms) to the aerial input (only the left
channel of the stereo signal). Measure the output on pin 22
(R_OUT) of IC7841 with an AC millivoltmeter.
6. Use the MENU LEFT/RIGHT keys to adjust the meter
reading to a minimum value (default HSA value is "31").
7. Press the MENU button to return to the top level SDAM
menu.
8. To ensure the HSA setting is saved:
– 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.
– Reconnect the television set to AC power.
– Turn the television set 'on' by using the 'POWER'
button on the remote control transmitter or the local
keyboard.
