The author analyses the fundamental structure. , working feature and main function of 12C general line that is applied to colour TV, and demonstrates its adjustment method in this article.
In this paper,we have introduced the theorem and way of remoulding moclel"FURi"HFC-321 colour television by "Rui kang" XHYK full function remote control system,which offers a way to solve the problem of adding remote control channel's extension which the old fashionecl colour television faced.
This paper analyses the principle of trouble in colour television struck by lightning,points out that the main way of lightning is from AC power to TV,and gives some maintenance examples. At last,it puts forward receptive demands at lightning and some steps for preventing lightning.
The system uses PC series port to accept the test results of 2849 white balancer. After dealing with the resluts, the system sends the adress and the data of the TV white balance decode chip to I2C busline board. The board communicates with TV I2C busline to realize the white balance autoregulation.
The article with the type of Toshiba D8 ss as an example,researches the application of I 2C in colored TV sets and discusses the application of I 2C in colored TV sets and discusses the working process of the I 2C system,its control,maintenance and adjustment according to the important difference between general CPU colored TV sets and I 2C colored TV sets.
Because the TV signal is a kind of pseudoperiodic signal, the matched filtering of color TV signals would yield high sidelobes which cause the range ambiguity.
Taking TCL's color TV production system as an example, this paper discusses the formation process and causes of the production system of China's manufacturing industry.
The new technique of colour television image analysis has been used to produce seven-colour contour maps of the radiodensity of micro-radiographs of enamel caries.
Color TV is a electron product which largely required and widely used. The article presented will summerize the new trend of color TV development to highly intergrated, function with parts, electric brain with intelligence, TV with double accompanying sound receiver,TV with multi-function and terminal, telecontrol technique and picture with high quality and TV with numbers in recent years.
In this paper,we have introduced the theorem and way of remoulding moclel"FURi"HFC-321 colour television by "Rui kang" XHYK full function remote control system,which offers a way to solve the problem of adding remote control channel's extension which the old fashionecl colour television faced.
In this paper,By an example of Thomson color TV, We analyse the fault of the power unit caused by the fluctuation of the system voltage,discuss the DC voltage regulator we .designed,and draw the test curves.
