List the contents of the above is the contents of all the tutorials that I made ​​and accompanied by an explanation with complete. How to measure voltage, repair steps, how to repair with right, how to measure the tube, how to measure the components and so you can see yourself with a list contents. All of the pictures. Can you prove.
Below is one example of the contents of the tutorial on the first page, if you want to learn more complete and clear can the message directly to this. Blog is made ​​in my original photo-photo own. In examples in this blog is my original photo and sentence explanation The original also my description own. Because results based on experience.

The following is a description of the function of each part:

Antenna: serves to capture the RF signals from television transmitters.
Tuner: functions to select the wave transmitter that will be accepted.
Inside there are tuner RF amplifier, mixer and oscillator.
RF amplifier duty to choose the transmitter to be received and then given to the mixer.
Mixer eventually produce a new frequency, then filtered into 2 frequencies are out of 38.9 MHz and 33.4 MHz.
The frequency of 38.9 MHz image carrier is frequency
The frequency of 33.4 MHz is the frequency of the sound carrier.
The two frequencies are then forwarded to the video IF amplifier.
Video IF: serves to strengthen the signals received from the mixer, then forwarded to the video detector.
Video detector: function detects image signals and sound then forwarded to the video picture carrier driver. Signal out image signals are detected up to a frequency 15 KHZ-5 MHZ, the sound carrier signal is detected to exiting new sound carrier signal 5.5 MHz (FM).
Video driver serves to separate the voice carrier signal, the image signal and the signal sincronisasi.
Image signal transmitted to the video output.
Voice signals transmitted to the sound IF amplifier.
Synchronization signal is transmitted to the sync separator.
Video output signal function reinforce the image and then forwarded to the cathode tube.
Sound IF amplifier serves to strengthen the voice signal is then forwarded to the FM detector, the detector detects the FM signal frequency of 5.5 MHz to live audio, audio amplifier and then to continue to loudspeaker. For the sound IF to this audio amplifier such as booster amplifiers usual.
Syncronisasi separator serves to adjust the images transmitted from the transmitter.
Vertical oscillator function generates a frequency of 50 Hz and then forwarded to the output drivers and vertical vertical, next to the vertical deflection and vertical deflection is open the image vertically (top down).
AFC function corrects the horizontal frequency of 15.625 KHz and forwarded to the horizontal oscillator.
Horizontal oscillator functions to generate frequency 15.625 Khz and then forwarded to the driver and then horizontally to the horizontal output next to the horizontal deflection and horizontal deflection is open picture horizontally (left-right).
Horizontal output also generates about 10-20 kv high voltage to the anode tube.
