ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a self-diagnosing system and method for a television receiver (TV), in particular, a system and a method for self-diagnosing a TV which enables a user to personally solve problems frequently caused by a user's inexperience with a TV or the malfunction of the TV itself.
2. Description of the Prior Art
In general, TVs and other household electric appliances include product manuals which explain how to use the products and how to solve simple problems with the products.
If a problem is caused in a product, the user can take necessary measures by referring to the manual and comparing the current problem with the problems described in the manual. By reference to the manual, the user can simply solve the problems caused by his inexperience with the product or malfunctioning of the product itself.
However, manuals can be easily lost and are somewhat difficult for older people or children to understand. Users generally request the repair services of an after-service center if they encounter trouble with their TV, rather than taking necessary measures as indicated by the product manual.
Thus, even cases where the trouble is simple such that the user can easily solve it by reference to the manual, the user will not be able to watch the TV until it is repaired. Also, the company manufacturing the product will be excessively burdened due to frequent service calls.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a self-diagnosing system and method for a TV which is convenient to use when solving trouble with a TV. According to the trouble-diagnosing system and method of the present invention, if a user selects the trouble-diagnosing mode key, the control section, in response to the user selection, displays a plurality of trouble-diagnosing menus and examples of the problems. The user who has read the trouble-diagnosing menu and examples of the problems, selects the example corresponding to the current problem. Then the control section will determine whether a solution exists for the selected problem, and if so, perform the solution to automatically fix the problem. For example, if a user selects a problem associated with lack of color in the display, the control section will automatically initialize the color balance data to default values to restore color.
For example, the control section will display a time setting program by an on-screen display (OSD) on the CRT so that the user can adjust the stored time. If the problem is not caused by the user's mistake, the control section will recognize that the video trouble resulted from another part's malfunction and will give a video and/or audio message that the user must request the repair services of an after-service center.
In one aspect of the present invention, the self-diagnosing system for a television receiver (TV) comprises:
a key matrix including a key for determining a self-diagnosing mode and keys for selecting self-diagnosing menus on the problems;
control means for identifying a corresponding example of the problem when the keys on the key matrix are selected, and providing instructions as to how to solve the problem through a video and/or audio signal;
storage means for storing at least one instructions to solve the problems and providing the instructions to the control means under the control of the control means; and
output means for outputting the video and/or audio signal provided from the control means to a cathode ray tube (CRT).
In another aspect of the present invention, the self-diagnosing method for a television receiver comprises the steps of:
a) selecting a self-diagnosing mode key;
b) displaying a plurality of self-diagnosing menus and examples of problems corresponding to the respective menus on a display screen;
c) selecting one of the examples corresponding to a current problem from the displayed examples using numeric keys provided on a remote controller;
d) initializing the stored data corresponding to the selected example of the problem, or displaying on the display screen or outputting through an audio signal the instructions as to how to solve the current problem, after identifying the type of the problem selected at step c).
