Method and apparatus for adjusting a display in an extinguished state
View Patent ↗A method ( 300 ) for controlling a display function of an apparatus such as a television signal receiver is capable of remedying a display locked in an extinguished state to thereby ensure that a usable display is provided. According to an exemplary embodiment, the method ( 300 ) includes steps of detecting a power on condition of the apparatus ( 330 ), determining whether at least one predetermined display parameter associated with the display function exhibits at least one predetermined value responsive to the power on condition ( 340 ), and adjusting the at least one predetermined display parameter if the at least one predetermined display parameter exhibits the at least one predetermined value ( 360 ).
1. A method for controlling a display function of an apparatus, comprising:
detecting a power on condition of said apparatus;
determining whether at least one predetermined display parameter associated with said display function exhibits at least one predetermined value responsive to said power on condition, wherein a display of the apparatus is in an extinguished state if said at least one predetermined display parameter exhibits said at least one predetermined value; and
adjusting said at least one predetermined display parameter to set the display a non-extinguished state.
2. The method of claim 1 , wherein said apparatus is a television signal receiver.
3. The method of claim 1 , wherein said at least one predetermined display parameter includes at least one of contrast and brightness.
4. The method of claim 1 , wherein said at least one predetermined display parameter exhibits said at least one predetermined value responsive to user inputs to said apparatus.
5. The method of claim 1 , wherein said at least one predetermined value is included within a range of predetermined values.
6. The method of claim 1 , wherein a display provided by said apparatus is unusable if said at least one predetermined display parameter exhibits said at least one predetermined value.
7. An apparatus capable of providing a display function, comprising:
memory means for storing data representing at least one predetermined display parameter associated with said display function; and
processing means for determining whether said at least one predetermined display parameter exhibits at least one predetermined value responsive to a power on condition of said apparatus, wherein a display of the apparatus is in an extinguished state if said at least one predetermined display parameter exhibits said at least one predetermined value, and for adjusting said at least one predetermined display parameter to set the display to a non-extinguished state.
8. The apparatus of claim 7 , wherein said apparatus is a television signal receiver.
9. The apparatus of claim 7 , wherein said at least one predetermined display parameter includes at least one of contrast and brightness.
10. The apparatus of claim 7 , wherein said at least one predetermined display parameter exhibits said at least one predetermined value responsive to user inputs to said apparatus.
11. The apparatus of claim 7 , wherein said at least one predetermined value is included within a range of predetermined values.
12. The apparatus of claim 7 , wherein a display provided by said apparatus is unusable if said at least one predetermined display parameter exhibits said at least one predetermined value.
13. A television signal receiver, comprising:
a memory operative to store data representing at least one predetermined display parameter associated with a display function; and
a processor operative to determine whether said at least one predetermined display parameter exhibits at least one predetermined value responsive to a power on condition of said television signal receiver, wherein a display of the apparatus is in an extinguished state if said at least one predetermined display parameter exhibits said at least one predetermined value, and to adjust said at least one predetermined display parameter to set the display to a non-extinguished state.
14. The television signal receiver of claim 13 , wherein said at least one predetermined display parameter includes at least one of contrast and brightness.
15. The television signal receiver of claim 13 , wherein said at least one predetermined display parameter exhibits said at least one predetermined value responsive to user inputs to said television signal receiver.
16. The television signal receiver of claim 13 , wherein said at least one predetermined value is included within a range of predetermined values.
17. The television signal receiver of claim 13 , wherein a display provided by said television signal receiver is unusable if said at least one predetermined display parameter exhibits said at least one predetermined value.
