The effect is due to mistracking, and because it is con\ufb01ned to one section of the picture it is unlikely to be due to a servo fault, or maladjustment of the tracking control. The bottom of the picture corresponds to the top half of the tape ribbon, and is read out by the head as the tape <i>leaves <\/i>the head wrap. The implication is that the tape exit angle from the drum is wrong, and it is likely that the trouble is con\ufb01ned to the <i>e<\/i><i>xit guide <\/i>or the adjacent section of head rabbet. The need for cleaning and position checking is more likely than a need for height adjustment unless the guide is loose or has been disturbed.  <\/p>\n<p align=\"justify\">In Fig. 23.6 appears another videorecorder fault, this time in the form of a glass-like bar of picture disturbance on replay of a tape recorded in a faulty machine. In fact the bar is the visible effect of a wrongly timed <i>head-switch point <\/i>during record. Normally it is hid- den at the bottom of the picture by the action of the head-drum servo which should ensure that the changeover point takes place at a point  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-k3lO2MrhYvs\/Vd8aTBxm99I\/AAAAAAAB2uE\/UL7ioZBGaYI\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B12%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0270\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0270\" src=\"http:\/\/lh3.googleusercontent.com\/-9zVnkO1iqOs\/Vd8aX5pn5gI\/AAAAAAAB2uc\/LnyX0jJxl_4\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B19%25255D.jpg?imgmax=800\" width=\"244\" height=\"173\" \/><\/a>  <\/p>\n<p align=\"justify\">in time just before the \ufb01eld sync pulses. If the offending bar is stationary the \ufb01rst check should be on the setting of the record switch- point preset and the monostable it controls. If the bar drifts up or down, an <i>unlocked <\/i>head servo is indicated; the correct action then is to check for correct <i>playback <\/i>servo lock on a known-good record- ing. If good lock is achieved the likelihood is that off-air \ufb01eld syncs are not reaching the head servo during record. If not, the head servo itself is suspect, and a \ufb01rst check would be for correct output pulses from the drum tachogenerator.  <\/p>\n<p align=\"justify\">The display of Fig. 23.7 is symptomatic of <i>w<\/i><i>hit<\/i><i>e crushing<\/i>, and could arise in a camera, TV set, monitor or videorecorder. It can normally only take place in a video signal ampli\ufb01er, and the trouble source is easily traced with an oscilloscope, progressively checking the video waveform until the non-linearity becomes evident. At this point the bias, supply voltage, input level and feedback arrangements should be checked.  <\/p>\n<p align=\"justify\">It is possible for the symptom to arise from overdeviation of an f.m. modulator or signal distortion (\u2018bottom crushing\u2019) in an a.m.  <\/p>\n<p align=\"justify\">i.f. ampli\ufb01er \u2212 check bias and a.g.c. voltages.  <\/p>\n<p align=\"justify\">Another video-stage fault is pictured in Fig. 23.8. The picture is heavily shaded from left to right and badly smeared. An immediate conclusion is that the luminance signal(s) is deeply modulated at line rate, and that it stems from a large ripple on some l.o.p.t.-derived power supply line. The most heavily loaded and worked is that for the 180 V or 200 V h.t. supply for the RGB output stages.  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-EjcVQFLnlW4\/Vd8adWcY99I\/AAAAAAAB2uk\/MvQEXmtvJFE\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B21%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0271\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0271\" src=\"http:\/\/lh3.googleusercontent.com\/-iQNf-rJ2fVg\/Vd8ah67WLSI\/AAAAAAAB2vE\/ATyrgDZizc8\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B16%25255D.jpg?imgmax=800\" width=\"162\" height=\"244\" \/><\/a>  <\/p>\n<p align=\"justify\">Most sets use \ufb02yback recti\ufb01cation to derive this supply, and since the picture is dark (high supply voltage) at left, which immediately follows \ufb02yback, and brightens (low supply voltage) as line scan progresses, the obvious conclusion is that the 180\/200V -line reservoir is low capacitance due to leakage or drying up.  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-AOHsLS0SG3c\/Vd8ak2hRVxI\/AAAAAAAB2vQ\/azMJW-lKCr8\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B7%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0272\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0272\" src=\"http:\/\/lh3.googleusercontent.com\/-AJ-QdVIO1UU\/Vd8apC-GLQI\/AAAAAAAB2vs\/VAwsh5iibEQ\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B18%25255D.jpg?imgmax=800\" width=\"244\" height=\"190\" \/><\/a>  <\/p>\n<p align=\"justify\">The display of Fig. 23.9 is a familiar one, and is due to a poor S\/N ratio in the vision signal. First check (preferably with another TV) that aerial signal strength is adequate, and that the r.f. connections to the tuner are correct. If so, the next check should be of the applied voltage to the tuner, sometimes easiest done by applying a known correct voltage to the a.g.c. input pin. The persistence of the symptom with correct gain-control voltage incriminates the tuner, whereas restoration of a good picture shows that the r.f. a.g.c. circuit (or its control pot) is in need of attention. Any \u2018low gain\u2019 fault which gives this degree of noise must invariably be in an early stage of the signal-handling circuits; low gain in the \ufb01nal i.f. ampli\ufb01er stage or in post-demodulator circuits gives a \ufb02at \u2018milky\u2019 picture rather than a snowy one.  <\/p>\n<p align=\"justify\">The multiple images of Fig. 23.10 illustrate a case where the TV screen is better diagnostic instrument than any piece of test equipment. The problem here is due to signal re\ufb02ections, and the strength and position of the ghost image with respect to the main one indicates the amplitude and delay of the re\ufb02ected signal, the latter easily calculated on the basis of 1 \u03bcs equals 1\u204452 picture width, which can then be expressed if required in terms of signal path length.  <\/p>\n<p align=\"justify\">While ghost images can arise from re\ufb02ection of the UHF signal from hills, tall buildings etc., they can be generated <i>within <\/i>the equipment: this photo was taken with the ground connection of the luminance delay line open to give multiple re\ufb02ections along the line.  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-osM5c4C4uuE\/Vd8atFh3eSI\/AAAAAAAB2wE\/wewH1h_3Fuw\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B9%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0273\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0273\" src=\"http:\/\/lh3.googleusercontent.com\/-fkI2dlGNcX4\/Vd8ayktyWsI\/AAAAAAAB2wc\/57XaWqMfRj4\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B4%25255D.jpg?imgmax=800\" width=\"157\" height=\"244\" \/><\/a>  <\/p>\n<p align=\"justify\">A likely effect of much shorter-term signal re\ufb02ections appears in Fig. 23.11.

Apart from an <i>e<\/i><i>y<\/i><i>eheight <\/i>check with a \u2019scope on the data lines, see Chapter 8, little can be done with ordinary test instruments. If the r.f. tuning and vision demodulator \u2018tank\u2019 coil tuning are correct, here is a justi\ufb01able case for testing by substitution \u2013 starting, perhaps, with a complete text-equipped TV set, because the aerial, distribution system, and downlead or feeder are prime suspects in these cases.  <\/p>\n<p align=\"justify\">Moving onto the timebase sections of a TV or monitor, a picture display like that of Fig. 23.12 again rewards careful analysis with an almost certain diagnosis. Here the screen is grossly overscanned in the vertical direction, with evidence of bad non-linearity. This indicates a large increase in the power applied to the \ufb01eld scanning coils. Of several possible causes, those of an increase in the intrinsic gain of the \ufb01eld ampli\ufb01er, or a large rise in the supply rail voltage to the \ufb01eld timebase are very unlikely; in the latter case, other symptoms would probably be present.  <\/p>\n<p align=\"justify\">An increase in generated ramp height is again unlikely, and could be quickly checked with an oscilloscope. The \ufb01rst check, though, should be made at the main output negative feedback loop which here is open-circuit.  <\/p>\n<p align=\"justify\">The opposite effect, \ufb01eld collapse, is the subject of Fig. 23.13. Care- ful study of the resulting single scanning line, however, reveals a slight undulation of the line at the extreme left, and this is the effect of a ringing pulse induced into the \ufb01eld scan coils from the line-scan pair  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-mfXd8CQqTZY\/Vd8bEms0ZNI\/AAAAAAAB2yE\/4K869M7Gox0\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B8%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0275\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0275\" src=\"http:\/\/lh3.googleusercontent.com\/-OHe5JN8YyIs\/Vd8bJnaxQrI\/AAAAAAAB2yc\/li8KRxlq2NM\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B13%25255D.jpg?imgmax=800\" width=\"244\" height=\"186\" \/><\/a>  <\/p>\n<p align=\"justify\">at \ufb02yback. This arises from a lack of damping in the \ufb01eld coil circuit, and is indicative of an open <i>y<\/i><i>o<\/i><i>ke <\/i>circuit. The \ufb01eld scan coils themselves are rarely responsible, and investigation is generally con\ufb01ned to the coupling components between coils and output stage. A single <i>v<\/i><i>ertical <\/i>white line, where scan and e.h.t. are derived from the same \ufb02yback transformer, is likewise indicative of a break in the immediate circuit of the scan coil, typically due to a defective or dryjointed S-correction capacitor or scan-balance coil.  <\/p>\n<p align=\"justify\">A line timebase fault is depicted in Fig. 23.14. The basic problem here is a gross timing error between line scan and video signal, caus- ing the line blanking period to appear on the screen. Its likely causes are perhaps less obvious without some thought. It is seldom possible for this error to arise in the line sync phase detector itself in a flywheel system; much more probable is that either its reference (incoming line sync) or feedback (line \ufb02yback) pulses are suffering an abnormal time delay. A check with a dual-trace scope will probably eliminate the former, and identify a problem in the pulse-feedback circuit between l.o.p.t. and line sync chip. A change in resistor value or leak- age in a capacitor is often responsible.  <\/p>\n<p align=\"justify\">Faults in PSU systems are common, and while many of them result in complete loss of picture and sound, others give a display symptom which immediately identi\ufb01es the fault area, and sometimes the actual component. Fig. 23.15 shows one such. The picture has two \u2018wasp- waists\u2019 which shows that the main power line bears a strong 100 Hz  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-o4c5BfKFIb0\/Vd8bNzNBHrI\/AAAAAAAB2zA\/K3HM78rO-_Q\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B6%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0276\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0276\" src=\"http:\/\/lh3.googleusercontent.com\/-1qfxO7CGlZ0\/Vd8bSWtBvdI\/AAAAAAAB2zc\/R31mHOni_3A\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B17%25255D.jpg?imgmax=800\" width=\"244\" height=\"222\" \/><\/a>  <\/p>\n<p align=\"justify\">ripple. This can only come from a full-wave mains recti\ufb01er system, and is almost certainly due to failure of the primary reservoir capacitor in the PSU. The bulging effect will generally move slowly up or down the screen because mains a.c. is not synchronous with TV transmissions.  <\/p>\n<p align=\"justify\">A <i>single <\/i>wasp-waist is an almost certain indication that <i>one <\/i>of the four diodes in the recti\ufb01er bridge is open, resulting in half-wave recti\ufb01cation.  <\/p>\n<p align=\"justify\">The screen image shown in Fig. 23.16 shows horizontal overscan, which would most likely be due to a fault in the \ufb02yback tuning of the line output transformer (check the capacitor(s) across the line output transistor c\u2212e junction); a fault or maladjustment in the E\u2212W raster correction circuit (start by checking whether the width control works); or an increase in supply voltage to the line output stage. While the latter possibility should certainly be checked, it is an unlikely one because the PSU over-voltage protection would normally prevent the fault being displayed.  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-knjDvghv28k\/Vd8bUmJ63UI\/AAAAAAAB2zk\/JCriaYhfQOU\/s1600-h\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B2%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0277\" border=\"0\" alt=\"TEST EQUIPMENT AND FAULT DIAGNOSIS-0277\" src=\"http:\/\/lh3.googleusercontent.com\/-bZouctNNCm0\/Vd8bXncEedI\/AAAAAAAB2z0\/2h0f51IhZ9o\/TEST-EQUIPMENT-AND-FAULT-DIAGNOSIS-0%25255B22%25255D.jpg?imgmax=800\" width=\"158\" height=\"244\" \/><\/a>  <\/p>\n<p align=\"justify\">\n<p align=\"justify\"><i><\/i> <\/p>\n<p align=\"justify\">\n","protected":false},"excerpt":{"rendered":"<p>SYMPTOM ANALYSES Fig. 23.5 shows a snow-and-noise bar across the extreme bottom of a videorecorder playback picture from a known-good tape.
