TELEVISION
Television is a well-known telecommunications media broadcast receiver that serves as a moving picture and sound, whether it is monochrome (black and white) or color. In general, how the TV box originated from an antenna that receives input radio frequency(RF) in the form of VHF and UHF frequencies that work seekers is set by the tuner and a wave, then the signal is processed and separated between the picture and sound, whilethe image is processed by and forwarded to the cathode tube screen, voice signals are processed to split into stereo, and then fed into the final amplifier and speakers.
Television image output device is currently using a variety of viewer technologies such asCRT, LCD, Plasma, DLP, and OLED. As for the additional input terminal for otherhardware, television unit also features a view of the terminal input for DVD players, video game consoles and personal hearing aid. Another input terminal are also oftenencountered, including RCA, mini-DIN, HDMI, SCART, and D-terminal. There is alsoequipped with inputs for recording sounds and images from the TV show. Most unitsequipped luxury TVs with Ethernet ports to receive data from the Internet, such as valuestocks, weather, or news. The entire TV unit produced since the early 1980s is alsoequipped with an infrared remote control to control the broadcast channel, sound,brightness, contrast, color, etc..

Basic Part of a Television :
POWER SUPPLY:
The circuit serves to convert AC current into DC which then distributed to the entire series.Power supply circuit is limited by the white line on the PCB and the areas inside the red box. Areas within the white line is the input circuit which is an area of high voltage (livearea). Meanwhile, the area inside the red box is the power supply output DC voltage is thendistributed to the entire TV series.
TUNNER:
This series consists of high-frequency amplifier (amplifier HF), mixer (mixer), and the localoscillator. Tuning circuit serves to receive the incoming signal (TV waves) from the antenna and turn it into a frequency signal IF.
Amplifier circuit IF (Intermediate Frequency):
This circuit serves as a signal amplifier to 1,000 times. The resulting output signal tuner(tuner) is a weak signal and is highly dependent on the signal transmitter, the receiver's position, and landscape landscapes. The circuit is also useful to get rid of another wave of unnecessary and muffle the sound carrier wave interference ministry disturbing images.
The detector circuit Video:
This circuit serves as a detector of the composite video signal coming out of the picture IFamplifier. In addition, this circuit also function as a silencer all signals that interfere becauseif there is another incoming signal will result in poor image quality. One signal that thedamping is the voice signal.
The series of AGC (Automatic Gain Control):
AGC circuit input serves to adjust the gain automatically. This circuit will stabilize itself inputtelevision signal swings so that the resulting output to be constant.
Synchronization deflection circuit:
This series consists of four blocks, namely the synchronization circuit, a series of verticaldeflection, horizontal deflection circuit, and the high voltage generating circuit.
Video amplifier circuit:
This circuit serves as a signal amplifier luminan derived from the video so it can run deteltorglass screen or CRT (catode ray tube). In the video amplifier circuit there are also a series of ABL (automatic brightness level) or a strong regulator automatic light that serves toprotect high voltage circuits of the charge voltage is more caused by strong light on the screen
