Adjust the horizontal drive (B3), horizontal width (B4), and the horizontal linearity (B5) alternately until the picture is symmet

5、rical from left to right. If adjustment of B3, B4, or B5 was necessary, repeat the adjustments of Bl, and B2. HORIZONTAL WAVEFORM ADJUSTMENT Connect the verical amplifier of an oscilloscope thru 1 megohm to terminal C of the horizontal oscillator transformer. Turn the horizontal hold control to sync

6、 the picture horizontally. Adjust the waveform adjustment (B6) until the broad and narrow peaks are of equal amplitudes (See Fig. 5 below). If necessary, keep the picture in sync with the hold controls while making this adjustment. ADJUST FOR EQUAL PEAKS 7T7T/T FIG. 5 HORIZONTAL LOCKING RANGE ADJUST

7、MENT Turn the horizontal hold control fully counter-clockwise and momentarily interrupt the signal by switching to another channel and back again. Slowly turn the hold control clockwise and note the least number of bars present just before the picture falls into synchronization. If more than three b

8、ars are present, turn the horizontal lock trimmer (B7) 1/2 turn counter-clockwise. If less than three bars are present, turn B7 1/2 turn clockwise. Repeat this check and adjustment procedure until three bars are present just before the picture falls into synchronization. o s 3 P K P K) P 5 2 O o - O
