CRT or CRT TV – a budget and working option (not always)

Выбор, подключение и настройка

A CRT or kinescope TV is a TV that uses a cathode ray tube (CRT) or CRT (Cathode Ray Tube) to display an image. CRT or CRT TVs are called televisions that transmit images using cathode ray tubes, or kinescopes. A similar detail was used in early versions of technology, produced in the 20th century until the zero years of this century.

Interesting! In the common people, CRT TVs are called “old” or “square” because of common associations.

Device and principle of operation

The device of kinescopes can be explained simply: the tube has several built-in guns, the color of which corresponds to the main color scheme (red, green, blue). During the operation of the electron beam, the guns “shoot” the screen covered with the phosphor, which causes the glow. It is light that forms the image from individual dots.

Fact! The CRT is the oldest type of television. For the period of 2022, most manufacturers do not produce such equipment, however, early models can be found from the owner-sellers.

Pros and cons of CRT

Old TVs have their advantages:

  • A wide range of different functional models.
  • Small prices for equipment.
  • Sufficiently reliable, time-tested working technology.
  • Less distorted color reproduction and high-quality images even on small screens.
  • Long service life (some models are able to work 15-25 years).

There are also disadvantages:

  • Technological screen size limitation (approximately 38 inches).
  • High dimensions, including the size and weight of the TV.
  • The presence of geometric distortions, “flare”, problems with focusing.
  • A significant lag behind modern technology is limited functionality, the impossibility of high-quality work with the latest devices.

Attention! CRT TVs are considered the most dangerous for vision: at a frame refresh rate below 100 Hertz, the eyes get tired faster, overwork and headaches can occur.

How to choose a kinescope TV

To choose the best kinescope TV, you should pay attention to the main characteristics:

  1. Approximate screen size . When choosing the diagonal of the device, you should decide in which room it will be installed. For small rooms, small TVs are suitable, for wide and long ones, you should take a larger screen.
  2. Technology used . Basically, kinescope technology has a frame flicker rate of 50 and 100 Hertz. For comfortable long-term viewing, it is better to choose high-frequency devices.
  3. Screen Format . Allocate 4:3 and 16:9 screens. The first one is suitable for watching TV shows on classic channels – this is the format that such a record has. To watch video from discs or cassettes, you must purchase a widescreen TV.
  4. Speaker type . There are devices with mono and stereo sound playback. If the recording source does not matter, a device with mono sound will do. Stereo speakers convey the direction of the sound better. You should also pay attention to the model and quality of the speaker: extra noise during operation is undesirable.
  5. Availability of additional devices and programs . Old TVs can be upgraded with the features of standard modern models.
  6. The presence or number of connectors for external equipment . If you plan to connect additional devices, you should choose TVs with the appropriate connectors.
  7. Existence of control buttons on the external panel . The TV can be equipped with both basic buttons and a whole set of remote controls. The latter option makes the device more cumbersome.

How much does it cost to buy a kinescope TV and for what conditions and situations

In modern times, kinescope TVs are practically not relevant. In addition to moral obsolescence, they have acquired the status of the most harmful to the health of the eyes and are not suitable for long-term viewing. However, such a device is worth buying if:

  1. The budget for the purchase is essentially organic . Old equipment is cheaper than modern models, if the price is not overpriced by the seller.
  2. The TV will be a secondary device : for example, if the owners want to purchase a second TV for another room or have a backup option in case the main or weak signal breaks (for example, no Internet).
  3. Long-term viewing is not planned : television has lost its relevance, programs are gathering fewer and fewer regular viewers.
  4. Equipment is purchased for temporary entertainment or outside urban conditions : for a country house, summer kitchen, viewing until complete repair and organization of the home.

The price of CRT kinescopes is incomparably lower than even BUS LSD panels

Interesting! Kinescopes are bought up for specific activities: extraction of non-ferrous metal, subsequent resale, obtaining rare spare parts.

It is difficult to name the exact price that is worth paying for such a TV. However, when purchasing, one should remember the moral and technical irrelevance of such equipment. In comparison with modernized TVs, kinescopes should cost several times less, within a few thousand rubles. You should not overpay when repurchasing: an overpriced price will not match the quality and operation of the device. What is useful in old CRT TV panels: https://youtu.be/Eg-tx_uE3Pg

Common CRT TV Problems

Most often, owners of kinescope TVs are faced with such breakdowns as:

  • Instability of the power system: problems with energy consumption, overspending.
  • Severe overheating of the case and parts of the device.
  • Visible damage to parts: formation of soot, leakage of working substances.
  • Signal quality problems.
  • Inability to connect to certain networks.
  • Involuntary switching on and off, the inability to independently control the modes.

Causes of problems and remedies

Each type of fault requires a special approach. In
case of power problems or electrolyte leakage, capacitors must be replaced: they have a limited life.

Important! When working with electrolyte and capacitors, follow safety precautions or contact a specialist. Elements of the power system are explosive.

Most problems with appliances are caused by overheating. It affects both the entire system and its individual parts. During continuous operation, there is a strong load on the insulation, LEDs and capacitors. If the main components overheat, the TV may turn off with a characteristic sound and resume operation after cooling down. To prevent overheating and damage to other parts, you should regularly clean the case from dust. Dust is the cause of contact closure and disruption of the stability of the boards. You also need to monitor the absence of moisture in the place where the TV is. If
image quality or signal strength suffers, the cause should be sought in the connection to the transmission via an antenna or cable. For later models of CRT TVs, you can install special programs that improve the signal level.

Important! If malfunctions in the operation of the CRT TV are noticed, diagnostics should be carried out not only for the main equipment, but also for auxiliary ones. It is necessary to regularly clean the control panel, change batteries, check the integrity of cables and other systems for connecting to programs.

In the absence of proper skills, it is recommended to contact the master to avoid problems with the repair.
