6、ounter-clock- wise 1/2 turn. 2. Turn the set on and set the contrast control to normal. Tune In a TV station, preferably a test pattern, and turn the horizontal hold control to the center of Its range. Turn the vertical hold control to synchronize the picture vertically. 3. Turn the horizontal frequ

7、ency adjustment B3 until the picture synchronizes horizontally. The setting of this adjustment is correct when a sudden twist of the hold control tends to throw the picture out of horizontal synchronization. 4. Turn the horizontal linearity tZ, (horizontal linearity large), B3 so the screw protrudes

8、 1/2 in., leave the adjustment in this position. 5. With the picture expander control set in small position, adjust the horizontal linearity #1, (horizontal damping small), B4, and the horizontal size, (horizontal size small), BS for a picture slightly wider than the picture tube face with best line

9、arity from right to left. If the proper width cannot be obtained, It may be necessary to readjust Bl. If Bl Is changed repeat steps 3, 4 and 5. 6. With the picture expander in the large position, no further horizontal adjustment should be necessary. VERTICAL LINEARITY ADJUSTMENTS The horizontal swee

10、p circuit adjustments should be performed before beginning the vertical linearity adjust- ments . i 1. Tune In a test pattern from a TV station and turn the contrast control to its normal setting. Turn the vertical hold, and horizontal hold, controls to properly synchronize the picture. 2. Set the p

11、icture expander to large. 3. Adjust the vertical size | 2 (vertical size large), control until the outer circle of the test pattern al- most disappears off the edge of the picture tube face. 4. Adjust the vertical linearity 12, (vertical linearity large), control for best linearity from top to botto

12、m of the picture. The vertical size and linearity controls are Interacting and should be adjusted alternately until proper size with best vertical linearity Is obtained. 5. Switch the picture expander to small. 6. Adjust the vertical size fl, (vertical size small), and the vertical linearity II, (ce

13、rtical linearity small), until the picture is of proper size with best linearity from top to bottom. HORiZ. LIN. HORIZ. DAMPING B4 x;- HORIZ. SIZE B5 * I VERT.
