LUXOR 5134 TYPE 18051341 YEAR 1984.

The  LUXOR  5134  TYPE 18051341  is a  20 inches (51cm) color television with 29 programs PLL synthesized tuning.
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.
The object of this system  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.


Was first LUXOR television model featuring the AV SCART socket.

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 !

This LUXOR  5134  TYPE 18051341  model series was introducing at the time the PLL synthesizer tuning system first time Microcomputer controlled with direct channel calling feature even from remote control. The PLL frequency synthesized electronic tuning system provides free and easy channel selection. and lets you tune directly to any channel using the channel number buttons (0~9 and key) on the front keyboard control !!

The  LUXOR  5134  TYPE 18051341 was featuring fist time The TDA3300 Motorola's third generation colour processing,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 the Automatic Black Level set-up.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.

First LUXOR TV model series featuring a monocarrier chassis horizontally placed for all functions.

Most TV manufacturers appear to be heading towards a common goal when it comes to designing a new chassis for future production. The idea which makes the most sense is to design a single chassis which will drive a variety of tube sizes, is easily adapted to suit different broadcasting standards (this makes exporting that much easier) and is capable of add-ons, e.g. teletext facilities. This approach reduces manufacturing costs by having a single production line for one p.c.b. containing all the common items. The production sequence then "forks" to allow for the different versions of the chassis, e.g. different components are required for 90° and 110° c.r.t.s. This type of design tends to suit smaller manufacturers. The Swedish company Luxor recently introduced their "unified" chassis design, the SX9. Luxor's total output is relatively modest and they identified their main market as being at the luxury end. It made sense therefore to develop a single chassis with as much built-in flexibility as possible.

The CRT TUBE IS A TOSHIBA BLACKSTRIPE.


 Luxor AB KONSUMENTELEKTRONIK was a Swedish home electronics and computer manufacturer located in Motala, acquired by Nokia in 1985.

Originally a manufacturer of tape recorders, radios, television sets, stereo systems, and other home electronics, it launched its first home computer, the ABC 80 in 1978. The succeeding ABC 800 series was introduced in 1981 with new releases in 1983 being produced until the ABC line was terminated in 1986.

The company was established in 1923 by Axel Harald Holstensson (1889 - 1979). He was the son of an ore loader and had no training other than a few years of elementary school. He worked as an electrician and eventually as a travel fitter and foreman at ASEA years from 1907 to 1918. In his spare time, he studied electrical engineering. In 1918, he moved to Motala and started an electronics store and installation company Motala Electric Agency (Swedish: Motala Elektriska Byrå). The post-war depression, however, led almost to bankruptcy situation was critical and the resort was to start building radios. Components procured from Germany and it was shown to be possible to sell a number of devices at a profit, so Axel Holstensson registered the Luxor Radio Factory Company (Swedish: Firma Radiofabriken Luxor) in 1923.
The name Luxor was apposite and then very topical as the Tomb of Tutankhamun had just been discovered near the city of Luxor in Egypt. Finnish company Nokia became a principal owner in the company in 1984. Computer production was discontinued in 1986, followed by television production in Motala in 1992, when the production moved to Finland. Instead, it produced receivers for cable and satellite television. But Nokia wanted to streamline its business to mobile telephony and therefore sold the satellite receiver business in 1998 to American company Space Craft Inc. The company continued to manufacture satellite receivers in Motala until 2002, when it was transferred to low-cost countries. In October 1997, Nokia sold its car speaker and audio amplifier business to Harman International Industries. A collaboration with the then Electrolux-owned Autoliv AB led to the company first became a partner for Luxor Electronics since 1998, buying the entire business. In Motala, is still manufacturing various types of electronic products for the automotive industry remains. The brand name was later sold to the Turkish company Vestel.
