WHITE WESTINGHOUSE (FORMENTI) W342 16" YEAR 1984

The WHITE WESTINGHOUSE (FORMENTI)  W342 16" is a portable color television with 16 inches (42cm) screen.

The set features;

• 29 programs PLL synthesizer 99 channels with bottom placed a red led display and local keyboard and remote control. This color television is featured with PLL frequency synthesized tuning system, a television tuning system employs a frequency synthesizer system for establishing the tuning of the receiver, featured with a Microcomputer driven synthesis system.A tuning system is provided in which the tuning function is substantially integrated in a microprocessor. A fixed modulus counter is cascaded with a programmable counter (or timer) found within the microprocesor thereby extending the counting range of the programmable counter. Then by prescaling the output of the local oscillator to a value below the toggle frequency of the microprocessor counter, the microprocessor may periodically measure the output frequency of the oscillator and, if necessary, generate correction signals therefor.
  Some prior art tuning systems for use with a voltage tunable tuner have utilized a plurality of preset potentiometers each adjusted to supply a voltage required to tune the tuner to a desired channel. Mechanical or electronic switches have been employed to connect one of the preset voltages at a time to the tuner. With this method of tuning, the channel being received is not accurately identified by the system. Initially, in order to set each of the potentiometers to permit reception of desired channels, a viewer must determine the channel being received by channel call letters and/or channel number identification periodically transmitted from the television station. Typically, after the channel being received has been identified, a plastic insert having the channel number printed thereon is placed in front of a lamp which will be illuminated whenever this channel is selected.
  Television receivers of the type under consideration frequently include a frequency synthesizer for tuning the receiver's local oscillator to the nominal carrier frequency of a selected television channel. Generally, the frequency synthesizer compares the local oscillator frequency to a reference frequency associated with the selected channel, and then varies the local oscillator frequency until it equals the reference frequency. Presumably, the receiver will now be correctly tuned to the selected channel.
  This method of tuning the receiver relies, of course, on the frequency of the incoming television signal being equal to its nominal or standard frequency.
  The object of this invention is to provide a tuning system which uses a frequency synthesizer implemented with a microprocessor.A further object of this invention is to provide a tuning system in which the tuning function occurs primarily within the microprocessor.
  These objects are achieved in a frequency synthesized tuning system comprising a variable oscillator and a microprocessor coupled to said variable oscillator for the control thereof, said microprocessor having a programmable counter therein, wherein the tuning function of said tuning system is substantially integrated within said microprocessor, characterized in that said tuning system further comprises means coupled between said oscillator and said microprocessor for extending the capacity of said programmable counter, whereby said programmable counter may be used for measuring the output frequency of said variable oscillator.
  The system employed in the tv permits utilization of a frequency synthesizer tuning system which correctly tunes to a desired television station or channel even if the transmitted signals from that station are not precisely maintained at the proper frequencies even in combination of a fine tuning adjustable by the user.
  Accordingly, it is an object of this invention to provide an improved tuning system for a television receiver.
  It is an additional object of this invention to provide an improved frequency synthesizer tuning system for a television receiver.

PLL SYNTHESIZED TUNING System Concepts:

INTRODUCTION Digital tuning systems are fast replacing the conventional mechanical systems in AM FM and television receivers The desirability of the digital approach is mainly due to the following features * Precise tuning of station frequencies
* Exact digital frequency display
* Keyboard entry of desired frequency
* Virtually unlimited station memory
* Up down scanning through the band
* Station ‘‘search’’ (stop on next active station)
* Power on to the last station
* Easy option for time-of-day clock In addition
" recent "developments in large scale integrated circuit technology and new varactor diodes for the AM band have made the cost-benefit picture for digital tuning very attractive System partitioning is extremely important in optimizing this cost-benefit picture as will be discussed.

SYSTEM DESCRIPTION
A simplified block diagram of a typical digitally tuned receiver is shown in Figure 1 Notice this receiver could be one for AM FM marine radio or television it makes no difference The frequency synthesizer block generates the local oscillator frequency for the receiver just as a conventional mechanical tuner would However the phase-locked-loop (PLL) acts as an integral frequency multiplier of an accurate crystal controlled reference frequency while the mechanical type provides a continuously variable frequency output with no reference Some method of controlling the value of the multiplier for channel tuning must be provided The other RF IF and audio video circuitry will be the same as in the mechanical tuning method There are many different ways to partition the frequency synthesizer system to perform the digital tuning function................

• A PHILIPS CRT TUBE of HI-BRI series.

• 2 antennas for both VHF and UHF channels reception.

• First  WHITE WESTINGHOUSE portable color tv with  An AV SCART connector backside.

• A SCART Connector (which stands for Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a standard for connecting audio-visual equipment together. The official standard for SCART is CENELEC document number EN 50049-1. SCART is also known as Péritel (especially in France) and Euroconnector but the name SCART will be used exclusively herein. The standard defines a 21-pin connector (herein after a SCART connector) for carrying analog television signals. Various pieces of equipment may be connected by cables having a plug fitting the SCART connectors. Television apparatuses commonly include one or more SCART connectors.

Although a SCART connector is bidirectional, the present invention is concerned with the use of a SCART connector as an input connector for receiving signals into a television apparatus. A SCART connector can receive input television signals either in an RGB format in which the red, green and blue signals are received on Pins 15, 11 and 7, respectively, or alternatively in an S-Video format in which the luminance (Y) and chroma (C) signals are received on Pins 20 and 15. As a result of the common usage of Pin 15 in accordance with the SCART standard, a SCART connector cannot receive input television signals in an RGB format and in an S-Video format at the same time.

Consequently many commercially available television apparatuses include a separate SCART connectors each dedicated to receive input television signals in one of an RGB format and an S-Video format. This limits the functionality of the SCART connectors. In practical terms, the number of SCART connectors which can be provided on a television apparatus is limited by cost and space considerations. However, different users wish the input a wide range of different combinations of formats of television signals, depending on the equipment they personally own and use. However, the provision of SCART connectors dedicated to input television signals in one of an RGB format and an S-Video format limits the overall connectivity of the television apparatus. Furthermore, for many users the different RGB format and S-Video format are confusing. Some users may not understand or may mistake the format of a television signal being supplied on a given cable from a given piece of equipment. This can result in the supply of input television signals of an inappropriate format for the SCART connector concerned.

This kind of connector is todays obsoleted !

 

• Sound speaker side placed toghether with an external speaker connector  too.
  

• The WHITE WESTINGHOUSE (FORMENTI)  W342 is apretty unique model with an interesting double function handgrip, allowing to obtain an inclined tv cabinet or a front vertically placing of the same as seen in pictures above.The objective of the present invention was early on to expand on the utility of relatively small, portable tvs with locking mechanism in determined viewing positions;and can be positioned within front or inclined way with a locking connection member installed along a side of the main body for selectively controlling rotation of few degree. The handgrip rectangle structure  acts as a switch between the two positions choice.
  

• The WHITE WESTINGHOUSE (FORMENTI)  W342 is also characterized by implementing as a first portable color tv the MOTOROLA TDA 3300 Motorola's third generation colour processing,Motorola's third generation PAL decoder system (Chroma III) employs a single 40 -pin i.c., type TDA3300. Amongst the features of this i.c. are low dissipation, typically 600mW, with a single 12V supply; a patented 90° phase - shift system requiring no adjustment; and direct inputs for on -screen (data, TV games, etc.) displays, with a complementary fast blanking input. Of particular interest is the beam limiting and automatic black -level adjustment system, the latter making it unnecessary to incorporate preset controls to set up the black level. These arrangements rely on three high -voltage transistors to monitor the beam currents, providing feedback signals for the i.c. If the reference voltage is exceeded, the beam current limiting action comes into operation, reducing the contrast. The system has been designed to enhance the set's video and digital signal handling capability. During the flyback time the feedback input impedance rises, activating a further internal comparator. This compares the tube's cut-off current (a hot cathode doesn't cut off completely) with another internal reference voltage. The resultant signal is integrated and added to the output (at the output clamp) to provide the automatic black -level correction. Readers may recall that a similar idea, using discrete circuitry, is employed in certain B and 0 colour chassis. The advantage is that the black level is held constant throughout the tube's life, with no grey scale drift.

The device will accept a PAL or NTSC composite video
signal and output the. three colour signals—needing only a simple
driver amplifier to interface with the picture tube ,furthermore it features first time an apparatus and method for the automatic setup of a CRT operating point, or dc signal level (black), as well as the contrast, or gain level (gray), of a video display by sampling the CRT signal level of the individual cathodes and locking the dc signal level to a common dc setup reference and gain level to a value determined by a common contrast control signal and gain reference. An apparatus and method in which a common brightness control signal is modulated by a common contrast control signal such that a brightness control pedestal is added to each video signal path of a video display whereby picture black level does not change with contrast. the system is provided for achieving and maintaining gray scale tracking in a multibeam, cathode ray display device, despite fluctuations in the electrical characteristics of the display device and of video amplifiers driving the device. Tracking is accomplished by measuring the actual beam currents produced during the applications of test signals to the amplifiers and automatically adjusting the biases and gains of the amplifiers in response to differences between the measured beam currents and predefined beam currents which should be produced. The invention can also be used to automatically stabilize the beam current in a single beam cathode ray display device.

•   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.

• The set is build with a unique type of Modular chassis design The modular equipment chassis can include a first top support, a first bottom support, a first side member, a second side member, and a first guide rail. 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.

This set has spark like pictures and colors and very high contrast and bright perfectly focused and was very reliable.

The set wasn't expensive and was fabricated by Formenti Industry in Italy in 1984

  FORMENTI GROUP HISTORY It was founded in Desio ( Milan ) from Carlo Formenti in 1947 , under the name Carlo Formenti sas, and began his activities with the construction of radio , designed by the same founder, private label and under contract with other brands.

In 1953 the activities were moved to a new factory with 80 employees and was launched early production of TV sets in black and white , mostly as a subcontractor for major brands like Telefunken , Singer and Siemens .

Three years later began exports to foreign countries, and always as a subcontractor produced devices with trademarks for the large retail chains in Europe.


In 1961 took over the Italian plant of U.S. Admiral of Concorezzo with its 1,000 employees and a production capacity of 500 units per day, the license for the brand , and continued with the production of television and radio.
Admiral was formed Formenti SpA based in Milan , Lombardy and the company began its period of expansion so that within a few years led her to be one of the largest in the industry nationally.

Moreover, the production was extended to the field of "white" with the start of production of washing machines .

During the sixties , the head office and administration of the company, which changed its name to Industrie Formenti SpA Italy, was moved to Liss .

In 1972 was inaugurated a new plant in Sessa Aurunca for the production of color televisions with brands Admiral, Phoenix , Philco , and Televideon Uranya. Formenti was actually the first in Italy to produce the equipment, but until 1976 were marketed exclusively in the Central European countries, especially France and Germany , where for some time had already begun broadcasting in color.

Since 1983 the Group Formenti appeared on the market with another brand, White-Westinghouse , which became the most important with TVs, VCRs and household products from the same company Brianza.
In subsequent years Formenti used other brands as DuMont and Schaub-Lorenz .

Partially affected by the general crisis of the Italian electronic, in 1984 the public financial REL entered the capital Formenti record the 27.75% of the shares . The company, which by then had 580 employees scattered in the two plants, however, was one of the few entries in orbit REL able to repair their accounts in a short time.

In 1989 was started the modernization and extension of the establishment of Sessa, the installation of assembly automation , which allowed the company to undergo an increase in productivity from 300 to 2,200 pieces per day,The establishment of Concorezzo was instead intended to produce a new monitor and display for professional computer and ATM .

The company's continued A successful period during the nineties . Its sales went from over 108 billion lire in 1991 to 310 made in 1999 . Meanwhile, the Group acquired it in Monza 1997 the brand Imperial and the failed Sèleco , noting the brands Brionvega and Tandberg and the establishment of Pordenone (activated in 1998 ), and finally the Formenti family formed a new group called Sèleco-Formenti SpA, the which Charles, the founder, assumed the presidency, while the sons John and Julius, held the positions of CEO and director, respectively .



But since the year 2000 for Formenti begins a period of severe crisis. The company's balance sheet records a large deficit due to declining sales, the latter factor caused by the aggressive competition of producers Turkish color TV, put on the market at competitive prices clearly and without adequate anti- dumping on the part of ' European Union .

Also as a result of the difficulties facing the company, it decided to close the two plants Concorezzo ( 2000 ) and Sessa Aurunca ( 2003 ), respectively, 130 and 440 employees, as well as staff reductions in the Friuli .

In 2004 the company was put into liquidation , and then it is decided by the commissioner, the Court of Monza that appointment as curator Professor. Francesco Fimmanò. After a long period of unemployment benefits for workers of the company, shed of Pordenone and brands Sèleco, Brionvega and Imperial in 2006 are awarded to the Super / / Fluo , a company based in Udine owned by the brothers Carlo and Marco Asquini. The new property will only tempoi to produce some brand Imperial model tv, radio, and a Seleco brand new LCD TV brand Brionvega before the bankruptcy of the same. From this to save the brand Super / / Fluo, while the other brands owned and acquired by Formenti will pass to the new property called Selek Brionvega Technology and the mark for both audio and video production will switch to SIM2 Multimedia, the renowned Italian company field projectors.
