ABSTRACT:
A bus-controlled television having function control units interconnected via a data line is provided and includes a remote controller, a microcomputer, and a memory. The remote controller generates mode control signals which respectively correspond to operational modes of the television and which are used to test various functions of the television. The controller selectively outputs one of the mode control signals as a selected mode control signal based on commands input to the controller by a user. The microcomputer inputs the selected mode control signal and designates one of the modes as a selected operational mode. Furthermore, the microcomputer outputs mode data corresponding to the selected operational mode via the data line to instruct one of the function control units to operate according to the selected mode. The memory stores values of the mode data for the selected operational mode. The modes of the television may include: a service mode for performing various control functions after the television has been manufactured, a factory mode for performing the various control functions while the television is being manufactured, an aging mode for preheating a cathode ray tube of the television, and a high speed mode for performing analog functions of the television at high speed. In addition, various methods are provided for performing the operation modes of the television.
