The SINUDYNE 2969 COLOR is a 26 inches (66cm) color television with 8 programs sensor button program change and potentiometric tuning search in drawbar box.
The mechanical turret approach to television tuning has been used almost exclusively for the past 60 years. Even though replete with the inherent disadvantages of mechanical complexity, unreliability and cost, such apparatus has been technically capable of performing its intended function and as a result the consumer has had to bear the burdens associated with the device. However, with the " recent " Broadcast demands for parity of tuning for UHF and VHF channels, the increasing number of UHF and cable TV stations have imposed new tuning performance requirements which severely tax the capability of the mechanical turret tuner. Consequently, attempts are now being made to provide all electronic tuning to meet the new requirements.
TV TOUCH-TUNING IC: With the developmente of application covering the use of m.o.s. devices for television and radio channel selection and indication a device relates to a specially developed m.o.s.-technology integrated circuit which is already produced in development quantities. The touch -tuner as the i.c. is designated ans was intended to replace mechanical push-button TV tuner mechanisms. It provides a sensing system which operates in conjunction with a finger -touch plate, a switching arrangement to control a varicap tuner and in addition outputs to operate channel indicating neon lamps. The sensing system comprises a very high -impedance circuit which is effectively shorted out by the resistance of a finger placed across the external touch plate. One side of the touch plate is connected to the sensing input of the i.c. and the other to a positive voltage which may be d.c. or a.c. When the touch plate is operated the channels are stepped through in sequence: the selected channel latches on and the appropriate indicator lights. The i.c. operates from a standard 33V varicap tuner supply and enables up to eight channels to be selected. Remote control can be applied to the system if required and the set is provided for that.
The invention relates to a tuning unit with bandswitch for high frequency receivers, especially radio and television receivers, having a potentiometer system for the control of capacity diodes, the said potentiometer system consisting of a plurality of parallel resistance paths along which wiper contacts can be driven by means of screw spindles disposed adjacent one another in a common insulating material housing in which a bandswitch formed of metal rods is associated with each tuning spindle.
In these tuning units, the working voltages of the capacity diodes in the tuning circuits are recorded once a precise tuning to the desired frequency has been performed. A potentiometer tuning system has great advantages over the formerly used channel selectors operating with mechanically adjustable capacitors (tuning condensers) or mechanically adjustable inductances (variometers), mainly because it is not required to have such great precision in its tuning mechanism.
Tuning units with bandswitches formed of variable resistances and combined with interlocking pushbuttons controlling the supply of recorded working voltages to capacity diodes are known. Channel selection is accomplished by depressing the knobs, and the tuning or fine tuning are performed by turning the knobs. The resistances serving as voltage dividers in these tuning units are combined into a component unit such that they are in the form of a ladderlike pattern on a common insulating plate forming the cover of the housing in which the tuning spindles and wiper contacts corresponding to the variable resistances are housed. The number of resistances corresponds to the number of channels or frequencies which are to be recorded. The wiper contact picks up a voltage which, when applied to the capacity diodes determines their capacitance and hence the frequency of the corresponding oscillating circuit. The adjustment of the wipers is performed by turning the tuning spindle coupled to the tuning knob. By the depression of a button the electrical connection between a contact rod and a tuning spindle is brought about and thus the selected voltage is applied to the capacity diodes. Since the push buttons release one another, it is possible simply by depressing another button to tune to a different receiving frequency or a different channel, as the case may be.
Moreover, using this arrangement, the only indication--during adjustment--of which channel is selected is by station identification.
It has a sensor keyboard for local commands, includes a plurality of tuning positions each defined by an adjustable potentiometer, a neon bulb indicator, a UHF/VHF switch and a two pole momentary contact touch switch. A common tuning capacitor has a tuning voltage developed thereacross for controlling the tuning of a varactor diode tuner. A source of reference potential is coupled across the tuning potentiometers and closure of any touch switch results in the tuning capacitor being charged from the voltage reference source through the selected one of the tuning potentiometers. The neon bulbs yield a visual indication of the selected tuning position. Circuitry for automatically placing control of the tuner to a preselected one of the tuning positions upon turn on of the receiver is also included.
All other commands are manual.
The SINUDYNE 2969 COLOR was first color television from SINUDYNE and is entirely based on semiconductors and a 110° degree CRT TUBE (TELEFUNKEN). It has a picture tube apparatus employing the so-called delta gun shadow mask The present invention relates to a color television picture tube type color cathode-ray tube which is provided with three electron guns positioned respectively at the vertices of an equilateral triangle, " the so-called delta gun
shadow mask ".
To obtain a fine color picture on the screen of the cathode-ray tube of this type, the following requirements should be satisfied that the electron beam is emitted from each electron gun onto the center of each corresponding phosphor dot on the screen of the cathode-ray tube, the purity of colors is high and the electron beams are converged onto a group of phosphor dots.
These requirements can be comparatively easily satisfied in the case of the cathode-ray tube with a spherically formed screen, whereas it is difficult to satisfy the requirements in the case of a narrow-necked, wide-angle deflection cathode-ray tube. The wide angle deflection cathode-ray tube is advantageous in practical use because the distance between the electron guns and the screen is small and the screen is almost flat with a curvature approximate to that of a flat surface; h
owever, it is necessary to control the electron
beams so that the electron beams may be emitted exactly onto the 3-color
phosphor dots on the screen because the incident angle and distance of
the electron beams which reach the phosphor dots on the screen have the
values proper to respective phospher dots.
It has a Transistorized horizontal deflection circuits made up of a horizontal switching or output transistor, a diode, one or more capacitors and a deflection winding. The output transistor, operating as a switch, is driven by a horizontal rate square wave signal and conducts during a portion of the horizontal trace interval. A diode, connected in parallel with the transistor, conducts during the remainder of the trace interval. A retrace capacitor and the deflection yoke winding are coupled in parallel across the transistor-diode combination. Energy is transferred into and out of the deflection winding via the diode and output transistor during the trace interval and via the retrace capacitor during the retrace interval.
In some television receivers, the collector of the horizontal output transistor is coupled to the B+ power supply through the primary windings of the high voltage transformer.
Furthermore it was featuring an unique and particular "grouped function" multi modular chassis technology.
The television receiver also includes a wiring harness including a plurality of wires interconnecting the electronic chassis and picture tube within the cabinet. A plurality of connectors are positioned on the main electronic chassis and are interconnected by the wires within the wiring harness. A plurality of electronic modules are positioned within the electronic chassis with each of the modules having at least one connector thereon. The connectors on the electronic modules care placed so as to mate with the connectors mounted on the electronic chassis for interconnection between the electronic modules and the picture tube. By this means the various electronic modules can be removed by unplugging the connectors and without requiring soldering or unsoldering of any wires in the set.
IN general the set is build with a Modular chassis design because as modern television receivers become more complex the problem of repairing the receiver becomes more difficult. As the number of components used in the television receiver increases the susceptibility to breakdown increases and it becomes more difficult to replace defective components as they are more closely spaced. The problem has become even more complicated with the increasing number of color television receivers in use. A color television receiver has a larger number of circuits of a higher degree of complexity than the black and white receiver and further a more highly trained serviceman is required to properly service the color television receiver.
Fortunately for the service problem to date, most failures occur in the vacuum tubes used in the television receivers. A faulty or inoperative vacuum tube is relatively easy to find and replace. However, where the television receiver malfunction is caused by the failure of other components, such as resistors, capacitors or inductors, it is harder to isolate the defective component and a higher degree of skill on the part of the serviceman is required.
Even with the great majority of the color television receiver malfunctions being of the "easy to find and repair" type proper servicing of color sets has been difficult to obtain due to the shortage of trained serviceman.
At the present time advances in the state of the semiconductor art have led to the increasing use of transistors in color television receivers. The receiver described in this application has only two tubes, the picture tube and the high voltage rectifier tube, all the other active components in the receiver being semiconductors.
One important characteristic of a semiconductor device is its extreme reliability in comparison with the vacuum tube. The number of transistor and integrated circuit failures in the television receiver will be very low in comparison with the failures of other components, the reverse of what is true in present day color television receivers. Thus most failures in future television receivers will be of the hard to service type and will require more highly qualified servicemen.
The primary symptoms of a television receiver malfunction are shown on the picture tube of the television receiver while the components causing the malfunction are located within the cabinet. Also many adjustments to the receiver require the serviceman to observe the screen. Thus the serviceman must use unsatisfactory mirror arrangements to remove the electronic chassis from the cabinet, usually a very difficult task. Further many components are "buried" in a maze of circuitry and other components so that they are difficult to remove and replace without damage to other components in the receiver.
Repairing a modern color television receiver often requires that the receiver be removed from the home and carried to a repair shop where it may remain for many weeks. This is an expensive undertaking since most receivers are bulky and heavy enough to require at least two persons to carry them. Further, two trips must be made to the home, one to pick up the receiver and one to deliver it. For these reasons, the cost of maintaining the color television receiver in operating condition often exceeds the initial cost of the receiver and is an important factor in determining whether a receiver will be purchased.
Therefore, the object of this invention is to provide a transistorized color television receiver in which the main electronic chassis is easily accessible for maintenance and adjustment. Another object of this invention is to provide a transistorized color television receiver in which the electronic circuits are divided into a plurality of modules with the modules easily removable for service and maintenance. The main electronic chassis is slidably mounted within the cabinet so that it may be withdrawn, in the same manner as a drawer, to expose the electronic circuitry therein for maintenance and adjustment from the rear closure panel after easy removal. Another aspect is the capability to be serviced at eventually the home of the owner.
The set is slightly rare because in Italy at the time there wasn't color broadcasting until 1978 and furthermore there aren't produced much of them anyway.
(The set is an original SINUDYNE and not a rebranded NORDMENDE)
SINUDYNE was an Italian manufacturer of radio and television sets.
It was founded in 1946 SEI-Società Elettronica Italiana S.p.A., by two mates : Antonio Longhi and Bruno Berti, and they started manufacturing radio apparates with tubes.
In 1954 the started producing television sets which was in the 70's theyr primary activity.
In 1959 the production was transferred at Ozzano dell'Emilia near Bologna.
