7、) Turn the set on and tune in a TV station, preferably a test pattern, and allow a few minutes warmup. b) Turn the horizontal hold control to fully counter-clockwise. The picture should remain in horizontal sync. c) Momentarily interrupt the signal by switching to another channel and back again. The

8、 picture will normally be out of sync. d) Slowly rotate the horizontal hold control clockwise and carefully note the number of bars just before the picture pulls into synchronization. There should be 3 to 4 bars just before pull in. e) The picture should pull into sync after approximately 90 of cloc

9、kwise rotation and should remain in sync for approximately 90 additional clock- wise rotation. At the extreme clockwise position the picture should be out of sync and show a single vertical or diagonal bar in the raster. SLIGHT RETOUCH ADJUSTMENT If the receiver failed the above check, proceed with

10、slight retouch adjustment as follows: 1) Turn the horizontal hold control fully clockwise. 2) Adjust the horizontal frequency slug (Bl) until a single vertical or diagonal bar appears in the picture. 3) Turn the hold control to maximum counter-clockwise. The picture will normally fall out of horizon

11、tal sync. If it does not, momentarily interrupt the signal by switching to another channel and back again. 4) Adjust the horizontal lock-in trimmer (B2) until 3 to 4 bars are present just before pull in, as the hold control is turned clockwise. 5) Repeat the check of horizontal oscillator. COMPLETE

12、HORIZONTAL OSCILLATOR ALIGNMENT If proper horizontal oscillator pull in range can not be obtained by the slight retouch alignment, the horizontal oscillator will require alignment using an oscilloscope as follows: a) Turn the horizontal lock slug (B3) fully out (counter-clockwise). b) Turn the horiz

13、ontal lock in trimmer (B2) and horizontal drive trimmer (B4) 1/2 turn counter-clockwise from tight. c) Turn the contrast control to approximately its normal position, and turn the hold control to fully counter-clockwise. d) Adjust Bt until the picture falls into synchronization. If sync cannot be ob

14、tained, turn B2 1/4 turn clockwise and repeat this step. e) Connect the low capacity probe of an oscilloscope between terminal C of L17 and chassis. f) Adjust B3 until the broad and sharp peaks of the waveform on the scope are of equal height as shown in figure 8. If necessary turn the hold control

15、to keep the picture in sync while adjusting B3. g) Remove the oscilloscope and turn the horizontal hold control to fully clockwise. Adjust Bl until the entire picture appears to move slowly across the face of the tube. The horizontal blanking signal should appear as a single vertical or diagonal bar

16、. h) Turn the hold control to fully counter clockwise, the picture will normally fall out of sync. If it does not, momentarily interrupt the signal by switching to another channel and back again. i) Carefully adjust B2 until 3 or 4 diagonal bars are present just before the picture pulls into sync as

17、 the hold control is rotated clockwise. j) Adjust the horizontal drive trimmer (B4) clockwise from fully out for the best compromise between horizontal linearity and line focus, (the trimmer screw will fall out if the screw is turned too far counter-clockwise). k) Adjust the horizontal linearity slu

18、g (B5) until the picture is symmetrical from left to right. It may be necessary to adjust B4 and B5 alternately for best results. 1) Adjust the width slug (B6) until the picture just fills the mask horizontally. m) Turn the horizontal hold control to maximum counter-clockwise and adjust Bl until the

19、 blanking bar appears in the picture as a single vertical or diagonal bar. n) Turn the horizontal hold control to synchronize the picture and perform the check of horizontal oscillator.
