15、P ADJUSTMENT The FM trap is adjusted at the factory to 100MC and normally should not be adjusted unless an FM station with a frequency other than 100MC causes interference. Tune in the TV station which the FM interference occurs and adjust A29 for minimum interference. If the FM station not on the a

16、ir, connect an AM signal generator to the antenna terminals as in oscillator alignment, and set generator to frequency of FM station causing interference, and turn the channel selector to the channel on which interference occurs. Connect the vertical input lead of an oscilloscope to alignment Point

17、C and chassis. Adjust A29 for minimum indication on scope. HORIZONTAL SWEEP CIRCUIT ADJUSTMENTS The horizontal hold control has sufficient range to compensate for normal variations and still provide horizontal synchronization. If replacement of tubes, or components, makes it necessary to make furthe

18、r adjustment, they should be made as follows: 1. Turn the horizontal frequency trimmer (Bl) 1 1/2 turns counter-clockwise from fully clockwise position. Turn the horizontal drive trimmer (B2) two turns counter-clockwise from fully clockwise position. Turn the horizontal lock-in trimmer (B3) 1/2 turn

19、 counter-clockwise from fully clockwise position. Turn the horizontal hold control to the midposition of its range. 2. Turn the set on and tune in a TV station, preferably a test pattern, and adjust the horizontal oscillator coil slug (B4) until picture synchronizes horizontally. 3. Turn the horizon

20、tal hold control fully clockwise, and adjust B4 until 8 to 10 horizontal blanking bars are visible sloping downward to the right. If this cannot be accomplished, turn Bl another turn counter-clockwise and repeat this step. 4. Turn the hold control counter-clockwise until picture is in sync, and cont

21、inue rotation of hold control until picture falls out of sync. The picture may not go out of sync, with the hold control at its fully counter-clockwise position. If this is true, momentarily remove the signal by switching to another channel and back again. The picture should be out of sync. Turn the

22、 hold control slowly clockwise and note the number of blanking bars present just before picture pulls into sync. There should be 3 1/2 to 4 1/2 bars present just before pull-in. If there are more than 4 1/2 bars, turn B3 1/4 turn clockwise and repeat steps 3 and 4. If there is less than 3 1/2 bars p

23、resent, turn B3 another 1/4 turn counter-clockwise and repeat steps 3 and 4 until this condition exists. X o o -g H Ul SP o ij K - o 01 J O _ JL n o * a.
