Abstract: PROBLEM TO BE SOLVED: To considerably reduce a job time by identifying a diagnostic history of an abnormality diagnosis item detected finally among display of diagnostic histories stored in a memory so as to make a job such as inspection of an electronic device efficient and easy. SOLUTION: The device is provided with a memory 21 storing a diagnostic history by a self-diagnostic function and a display means 19 properly displaying the diagnostic histories stored in the memory 21. When the diagnostic history of an abnormality diagnosis item is going to be displayed on the display means 19, a system microcomputer 20 reads data from a prescribed address of the memory 21. Then an item generate finally and denoting an abnormality whose flag is set is retrieved. When the abnormality diagnostic item generated finally through this retrieval is discriminated, the system microcomputer 20 changes color data of columns of item names of abnormality diagnostic items and the number of times of occurrence and display equivalent to one screen are transferred to the display means 19.

Abstract: PROBLEM TO BE SOLVED: To deal with partial destruction generated in a non-volatile memory as well concerning a television receiver with which control data are stored in the non-volatile memory. SOLUTION: The control data are stored in non-volatile memories 6 and 7. The standard values of control data are stored in ROM 8 and 9. When a command for setting at the standard values is applied by a commander 33 or an input key 31, the control values in the nonvolatile memories 6 and 7 are switched to the standard values of control data in the ROM 8 and 9. Therefore, even when the nonvolatile memory is destroyed, the television receiver can be operated.

Abstract: PROBLEM TO BE SOLVED: To always receive all the channels in the best state by prohibiting the function of stereo demodulation for each channel to be received. SOLUTION: A prohibiting means prohibiting the stereo modulation of a multiplex audio signal is provided for a tuner 2, and the operation of this prohibiting means is set by a microcomputer 16 for main control 16 and a memory 22. In this case, information on whether a stereo mode or a forced monophonic mode is selected at the time of receiving the stereo broadcast of the tuner 2 is set in auto stereo information. In addition, auto stereo information after change is transferred to a tuning microcomputer 3. Then auto stereo control data is transferred to the U/V tuner 2. In addition set auto stereo information is stored in the area of CH 1 of the memory 22. Similarly auto stereo information is set to all the channels to be received.

Abstract: PROBLEM TO BE SOLVED: To satisfactorily discriminate a picture mode by superimposing prescribed DC to a chroma signal outputted by an output terminal and a discriminating the signal at the time of a full mode display. SOLUTION: A video signal and a Y/C separation signal from a switching circuit 7 are supplied for a picture mode discrimination circuit 24. The picture mode discrimination circuit 24 detects an S1 signal superimposed to a VBID signal inserted to the video signal and a chroma signal supplied for an input terminal 8, the information that a decoder 10 is decoding EDTV-2 and black belts provided at the upper and lower parts of a luminance signal to discriminate a picture mode which should be selected. In this case, at the time of executing a full mode display, for the luminance signal Y, DC 5V is superimposed to the chroma signal of the Y/C separation signal taken out by the output terminal 19, and the VBID signal showing the full mode is inserted in the vertical blanking period of the video signal to finish the processing.

Abstract: PROBLEM TO BE SOLVED: To attain a screen display in an excellent way at all times by inhibiting an automatic screen mode changeover under a prescribed condition so as to prevent useless switching. SOLUTION: Reception signals by tuners 2, 5 and a video and aural signal received by a video input terminal 7 are fed to a switching circuit 8, which selects a desired signal. Then a video signal outputted from the circuit 8 and a Y/C separate signal are given to a screen mode judgement circuit 26, in which an ID signal in which a non-display black stripe is inserted to the video signal is detected to judge the screen mode to be selected. The judgement information is fed to a main control microcomputer 22 via a bus line 23. Furthermore, a control signal from the microcomputer 22 is fed to a video processing circuit 10 and a deflection circuit 17 via the line 23. Thus, nonlinear control by the deflection system 18, write read address control for an image processing memory by the circuit 10 and screen mode changeover by pattern magnification and expansion are conducted. Thus, even in the case of the receiver judging the display pattern size and switching it, automatic changeover is inhibited.

Abstract: PURPOSE: To immediately display a teletext even when a broadcast station to be received is switched. CONSTITUTION: At the time of receiving the broadcast station for a master screen, by turning a tuner 14 to the one for receiving the broadcast station for a slave screen or the one for receiving the teletext, since the broadcast station received in the tuner 14 is not changed even when the broadcast station for the master screen is switched, the broadcast station received for the slave screen is not changed no matter what broadcast station is on the mester screen. Thus, regardless of the broadcast station of the master screen, the broadcast station selected for the slave screen is not changed, and when the broadcast station for the slave screen performs the character broadcast, the character broadcast is displayed regardless of the selection of the broadcast station for the master screen.
