RECEIVER TELEVISION BLACK
WHITE BLOCKS
Teknologi dan Rekayasa
1. TUNER
 Tuner : receive
input sinyal (TV
wave) from antena
and convert to
frecuency IF
sinyal.
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.

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
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

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

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

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