It smells like burnt plastic from the monitor

The system unit stores and processes the necessary information. The monitor is necessary in order to visualize the work process, to monitor its progress and the results obtained in real time. In addition, thanks to it, you can enter data. The most important part of the technique is the matrix. However, other structural details are also required to ensure operability. Sometimes some of them fail and performance is impaired.

It smells of burnt plastic from the monitor. The reasons

The most common monitor malfunctions are:

  • It does not turn on.
  • The image blinks or goes out periodically.
  • Turn off the device.
  • Vertical or horizontal stripes of different colors appeared on the screen.
  • The device is noisy.
  • It smells of burnt plastic from the monitor.

Some of these faults are software, and some are hardware. If the malfunction is caused by a malfunction in the software, you must reinstall and correctly configure the software.

However, if the problem is in the components, then repair and replacement of failed parts may be required. The failure of some elements can manifest itself in the form of a violation in the transmission of the video signal, for example, the picture is distorted or stripes appear. But it happens that a persistent smell of burning starts to come from technology.

The reasons for this is that some of their structural elements of the device burned out.

In addition to the matrix, the monitor contains:

  • Transistors
  • Transformers
  • Inverter
  • Screen backlight.
  • Capacitors
  • Power Supply.

Failure of any of them will lead to the burning smell and failure of the device.

The main causes of failure of these elements are:

  • Constant overheating of the device. This may be due to the fact that the monitor is near heating appliances.
  • Regular power surges. For the normal functioning of electrical appliances, they need a constant voltage equal to 220 V. But sometimes it can be significantly higher than this value. Monitor elements are extremely sensitive to these surges and even the slightest voltage drop can trigger the output of one or more of them.
  • The device could be assembled with a factory defect causing soldering and bad contacts. This can lead to a short circuit and, as a result, to burnout of the elements.
  • All devices have the ability to accumulate dust, which leads to overheating.

What to do?

Whatever you have to repair the device or buy a new one, you must:

  • First you need to measure the voltage in the network. If, at the same time, surges were noticed, then a voltage stabilizer is required. This device provides constant maintenance of the voltage at the optimum level of 220 V. It also protects against surges, drops and various noises. As a result of this, the reliable functioning of the monitor is ensured, and its life is also extended.
  • If the device is near a heat source, you need to move it so that it does not heat up.
  • It is also necessary to clean the monitor of dust. To do this, remove its back cover and carefully remove all dirt and dust. This can be done with a vacuum cleaner or hairdryer.
  • If, during the dismantling of the monitor, the defect allowed during production was found, then most likely you will need to buy a new one.

The monitor is an important and rather fragile device, which requires ensuring the correct conditions for operation, as well as periodic and thorough cleaning.
