SELF-DIAGNOSTIC METHOD AND DEVICE FOR DIGITAL TELEVICION
First Claim
1. A self-diagnostic device for a digital television, said digital television comprising at least one input interface, at least one processing unit, a scalar and a screen, said input interface being connected to said processing unit, said processing unit being connected to said scalar, and said screen for displaying images, said self-diagnostic device comprising:
- a starting unit, for generating a starting signal; and
a diagnostic unit, connected to said starting unit, said scalar and said processing unit, said diagnostic unit receiving said starting signal and generating a diagnostic signal to said processing unit, and said processing unit generating a reply signal and transmitting said reply signal back to said diagnostic signal.

Abstract
A digital television comprises at least one input interface for transmitting input signals, at least one processing unit connected to the input interface to receive the input signals and processing the input signals to output signals and then outputting the output signals, a scalar connected to the processing unit for receiving, adjusting and transmitting the output signals, a screen for displaying the output signals from the scalar, a diagnostic unit for generating a diagnostic signal, a storage unit and a starting unit for generating a starting signal and transmitting to the diagnostic unit to cause the diagnostic unit to start operating.

8. A self-diagnostic method for a digital television, said digital television comprising at least one input interface for transmitting a input signals, at least one processing unit connected to said input interface to receive said input signals and outputting output signals after processing said input signals to be said output signals, a scalar connected to said processing unit and receiving, adjusting and transmitting said output signals, a screen for displaying said output signals from said scalar, a diagnostic unit connected to said processing unit for generating a diagnostic signal, a storage unit connected to said diagnostic unit, and a starting unit connected to said diagnostic unit for generating a starting signal to said diagnostic unit, said self-diagnostic method comprising the following steps:
-
Transmitting said starting signal from said starting unit to said diagnostic unit;
Transmitting said diagnostic signal to said processing unit after said diagnostic unit generates said diagnostic signal;
Transmitting a reply signal back from said processing unit to said diagnostic unit after said processing unit generates said reply signal; and
Displaying a diagnostic result according to said reply signal on said screen through said scalar. - View Dependent Claims (9, 10, 11, 12)
