Soal Memperbaiki/Reparasi Televisi Smk Kelas Xi Elektronika

1. Alat yang digunakan untuk menyolder komponen elektronika pada papan PCB adalah ...

The correct answer is solder because solder is the tool used to join or connect electronic components to a PCB (Printed Circuit Board) by melting the solder and creating a bond between the components and the board. Solder is a metal alloy with a low melting point that becomes liquid when heated and solidifies when cooled, providing a strong and durable connection between the components.

2. Gejala kerusakan Televisi seperti tampak pada gambar terletak pada blok ...

Vertikal

Horisontal

Regulator

Tunner

Sinkronisasi

The given correct answer is "Vertikal". This suggests that the symptoms of the television damage, as shown in the picture, are related to the vertical block. The vertical block in a television is responsible for controlling the vertical movement of the picture on the screen. If there is a problem with the vertical block, it can result in issues such as a distorted or skewed picture, horizontal lines, or a rolling picture. Therefore, based on the symptoms described, it is likely that the damage is occurring in the vertical block of the television.

3. Komponen manakah yang mudah rusak pada waktu penyolderan?

Resistor dan Elco.

Diode dan Transistor.

IC dan Transistor.

Diode dan IC.

Kuprox.

During soldering, the IC (Integrated Circuit) and Transistor components are more prone to damage. This is because these components are sensitive to heat, and excessive heat during soldering can cause them to malfunction or become permanently damaged. It is important to handle these components with care and use the appropriate soldering techniques to minimize the risk of damage.

6. Tegangan ekstra tinggi yang dihasilkan trafo flyback untuk keperluan anoda tabung adalah,

1.000VDC – 220VDC.

15VDC.

100VDC – 1000VDC.

1.000VDC – 2.000VDC.

10.000VDC – 30.000VDC.

The correct answer is 10.000VDC – 30.000VDC because the question asks for the extra high voltage produced by a flyback transformer for the purpose of the tube's anode. This voltage range is within the typical range for flyback transformers used in CRT (cathode ray tube) displays, which require high voltages to accelerate electrons towards the screen.

7. Gambar bergetar getar dengan suara gemeretak sering disebabkan oleh,

Transistor catu daya.

Kondensator pada trafo filter IF video.

Resistor pada blok horisontal terbakar.

Elco pada rangkaian tunner.

Semua Benar

The correct answer is "Kondensator pada trafo filter IF video." This is because a vibrating image with crackling sound is often caused by a faulty capacitor in the IF video filter transformer.

Explanation

The correct answer is "Kondensator pada trafo filter IF video." This is because a vibrating image with crackling sound is often caused by a faulty capacitor in the IF video filter transformer.

8. Sistem yang digunakan dalam pengiriman sinyal dari stasiun pemancar TV adalah,

Sistem AM, FM dan sistem Auto.

Sistem NTSC,PAL dan SECAM.

Sistem AM,FM dan MW.

Sistem NTSC,PAL dan Auto

Sistem RF,IF dan AF.

The correct answer is "Sistem NTSC, PAL, dan Auto." This is because NTSC and PAL are two different analog television broadcasting systems used in different parts of the world. NTSC is primarily used in North America, while PAL is used in Europe, Asia, and other parts of the world. Auto refers to the automatic tuning feature in modern television sets that can detect and switch between different broadcasting systems.
