How to make a monitor live a long, long notice-hardware maintenance

In many computer accessories, the longest life of the components on the number of monitors. For example, my computer has been upgraded many times, but it is the 15-inch monitor that has stayed with me. Because the monitor is used for a long time, it is easy to be affected by environmental factors including temperature, humidity, dust, electromagnetic interference, electrostatic and so on, causing different degree of injury or formation failure. Therefore, the correct use of the display, pay attention to monitor the day-to-day maintenance and maintenance, is to determine its "longevity" or not important factors.

Humidity can not be too high and too low
The humidity of the display environment should be kept between the 30%~80%, once the indoor humidity is above 80%, the display inside will produce condensation phenomenon. Power transformers and other coils are also prone to leakage after damp, a long time even have the possibility of mold broken lines. In addition, the high pressure components of the monitor in the case of high humidity is also very easy to produce discharge phenomenon, the machine components damp easily rust, corrosion, serious when the circuit board will short-circuit.
On the contrary, when the indoor humidity ≤30%, it will make the display of mechanical friction part of electrostatic interference, internal components, especially high-pressure package by the possibility of electrostatic damage increased, the impact of the normal work of the monitor, serious cases will also cause the use of personnel injuries and display scrap.
Therefore, the display of the use of the environment must pay attention to moisture-proof, long time without the display, you can regularly power for a period of time, so that the display when the heat generated by the machine will be driven out of the moisture. At the same time, in order to prevent static electricity, the proposed computer grounding, especially in the northern climate dry environment.

Second, control indoor temperature
Picture tube As a large heat source of the monitor, the operating performance and service life will be greatly reduced in the environment of high temperature, some of the solder joints may be caused by solder melting off the open circuit, so that the display work instability. At the same time, the components will accelerate aging, light will cause the display "strike", heavy may penetrate or burn other components.
So, leave enough space around the display to let it "breathe". In hot summers, if conditions permit, it is best to place the display in air-conditioned rooms or with an electric fan.

Third, to avoid strong light direct photo
If the monitor is exposed to strong light, time will easily accelerate the aging of CRT phosphor, reduce the luminous efficiency (in strong light irradiation environment, facing the display staff, eyes are also very vulnerable to the screen reflected light damage). Therefore, the user does not put the display in the light of the strong place, it is best to put the monitor in the lighting can not directly illuminate the place or the interior of the light adjustment soft.

Iv. Prevention of Dust
Because the voltage in the monitor reaches 10kv~30kv, it is easy to attract dust particles in the air, especially in the instant of the switch machine. A lot of maintenance practice has proved that the threat of dust on the computer is very obvious, in the dusty environment work, because the printed circuit board will absorb dust, dust deposition will affect the thermal distribution of electronic components, so that the circuit board components on the temperature rise, leakage and burn components. Dust may also absorb moisture and corrode the electronic circuitry inside the display, causing some inexplicable problems. So the dust is small, but the damage to the display can not be underestimated.
To effectively prevent dust hazards, to ensure that the monitor is used in a relatively clean environment, we should buy a special dust cover for the display, each time after use should be in time with dust cover on the cover (pay attention not to the shutdown immediately after the hood, because the monitor after the shutdown requires a certain amount of time to heat). At the same time, we should do more cleaning, with a soft dry cloth carefully from the center of the screen, spiral outward wipe, incorrect wiping method will be left on the screen scratches, causing permanent damage. Also must not use the chemical solution such as alcohol to wipe, more cannot use the coarse cloth, the paper and so on the article to wipe the display screen, also do not spray the liquid directly to the screen (note: All cleaning work must be after unplug the power cord to carry on).

V. Avoid magnetic field interference
Electromagnetic field interference refers to the voltage and current in the circuit or environment that should not appear. The main sources of electromagnetic interference are power supplies, components, wires, joints, cooling fans, fluorescent lamps, lightning and electrostatic discharge, as well as televisions, refrigerators, electric fans, such as electricity consumption of large household appliances, if they are too close to the display, these devices will be likely to generate electromagnetic interference on the display.
In use, we should put the display in the distance from other electromagnetic fields (the most typical example is not to put the PC speakers too close to the monitor, even the magnetic speakers should pay attention to). Usually if there is a condition, you can often use the display degaussing function degaussing.
In addition to the above considerations, we in the actual use, there are many small places worthy of the attention of readers. In fact, the biggest damage to the monitor is also the user itself, some of our bad habits on the display of damage far more than environmental factors on the display of damage.
1. Do not stack debris on the display, so as not to affect the normal display of thermal acceleration components aging.
2. When the function knob on the monitor panel is pressed, it should be slow and steady, not hard to adjust to prevent damage knob.
3. If the monitor is too long, the brightness of the display may be reduced and the rays cannot be focused.
4. Although the operating voltage of the monitor is relatively large, it may be damaged by the instantaneous high-pressure impact, so it should be used with a fuse socket. If conditions permit, preferably with a UPS (uninterruptible power supply).
5. In use, can slightly reduce the display brightness (appropriate), which can slow down the fluorescent tube phosphor aging speed.
6. The refresh rate of the display is set appropriately, so that it does not have to use too high a refresh frequency to prolong the life of the display.
7. Do not smoke in front of the monitor, the tar in the cigarette will be harmful to the display coating.
8. Do not often switch machines, switching machine high voltage changes in the life of the display has a great impact.
