1 PARTS AND FUNCTION IN THE SYSTEM RECEIVER BLACK WHITE TV TELEVISION REPAIRING RECEIVER TELEVISION SYSTEM By Sarbini, S.Pd SMK Muh 3 Yogyakarta

2 Teknologi dan Rekayasa RECEIVER TELEVISION BLACK WHITE BLOCKS

3 Teknologi dan Rekayasa 1. TUNER  Tuner : receive input sinyal (TV wave) from antena and convert to frecuency IF sinyal.

4 Teknologi dan Rekayasa 2. IF AMPLIFIER  Functions brave as a signal coming from the tuner up to 1000 times. Ouput signal generated penala (Tuner) is a weak signal and is highly dependent on the distance relay, the position of the recipient and the expanse of nature.

5 Teknologi dan Rekayasa 3. Video Detektor Series  Function detection composite video signal exit of the IF video amplifier. It also serves to muffle the sound signal will result in poor quality images

6 Teknologi dan Rekayasa 4. Video Amplifier Series Functions This series is brace as a signal from the detector luminan coming from the detector so that it can run a picture tube or CRT (Catode Ray Tube)  Penguat IF (Intermediate Frequency)  Detektor Video  Video Amplifier

7 Teknologi dan Rekayasa 5. Stabilizator Receiver TV Wave Series.  Rangkaian penstabil penerima gelombang TV diantaranya adalah AGC dan AFT. Automatic Fine Tuning berfungsi mengatur frekuensi pembawa gambar dari penguat IF secara otomatis

8 Teknologi dan Rekayasa 6. Sinkronization Deflection Series Rangkaian ini terdiri dari empat blok yaitu:  Sinkronization Series,  Vertikal deflection series,  Horizontal deflection series,  High Voltage Generate

9 Teknologi dan Rekayasa 7. Sound Series Separated information sinyal (audio) from signal audio carrier and amplifiying until can listening by audience.

10 Teknologi dan Rekayasa  IF sound carrier signal will be detected by the frequency modulator (FM).  Power Amplifier (Sound Output) : Amplifying audio signal until be able vibrate loudspeaker.  Loudspeaker : convert audio signal audio to sound.

11 Teknologi dan Rekayasa 8. Power Supply series  Function to convert AC to DC current which is distributed to the all series need.  Area in the white line is the series of input which is a regional high-voltage (Live Area). Meanwhile, the area in a red box is the power output portion of the DC voltage distribution to the all TV series

12 Teknologi dan Rekayasa Power Supply Series

13 Teknologi dan Rekayasa 9. High Voltage Generator Produce high voltage for activate CRT until be able to produce electrons for video display.

14 Teknologi dan Rekayasa 10. Horizontal Deflection Yoke  Generate enough current deflection for used scanning electric beam horizontal direction.  Generate high voltage through the coil secunder fly back to continue to the anoda electrode and CRT focus electrode.
