The display of computer maintenance.
Represented by "face" of the computer as an important bridge of communication with the computer. But people tend to only the method. Buy it, ignore it after the purchase and maintenance, inspection, reliability and service life results were significantly shorter. According to statistics, 50% of the Failure of the display by the poor. Environmental conditions caused by incorrect operation or failure due to poor management over 30%, the actual damage because of poor quality or nature of a crash. 20% shows that the environmental conditions and factors that lead to the failure of the human major display. Therefore, the user must understand and more about your impressions of the general maintenance and repair.
Screen long-term placement in a variety of complex environment and easily by environmental factors such as temperature, affected. Damp, clean, electromagnetic interference. And static electricity generator
First, moisture factor.
★ moisture Effects show
If the indoor humidity 80% when ≥ possible. Result: the display humidity 30% ~ 80% of the work. But if the humidity over. 80%, the display of steam in coil within the company for transformers and others. Any easier to produce a leak to the fungus. Wet can share the connection and the screen to easily generate high pressure drop, machine components, rust, corrosion cause serious circuit. Short circuit.
If the indoor humidity ≤. 30% shows some of the mechanical friction in the production of static electricity in parts of the possible increase damaged by static electricity can affect the show. Professional battery. TOSHIBA. PA3465U - 1BRS
★ the hazard of moisture on the screen or can not be avoided.
Display must focus above all moisture in the rainy season. But pay attention to this point. A long time do not show you the power to do some work at regular intervals to monitor the heat generated when the work to distribute moisture content.
A second factor is lighting.
Study the effects ★ light.
The display of the sun or bright light for a long time and is easy to age. CRT phosphor and reduce the effective lighting. (Given this environment, the page displays the work of the employees are also prone to eye injury).
★ How you can avoid harmful factors on the display light?
How much easier can not be in place by strong sunlight or the light can be found must be present hanger Darks order the intensity of light.
Third, the dust factor.
★ impactthe small screen dust.
During high-pressure checks. 10kV ~ 30kV, light as high pressure dust in the air to win. The threat of dust in the computer, it is clear a lot of action in the maintenance an environment that is filled with dust. Circuit absorbs dirt, dust affects the accumulation of heat from electronic components, printed circuit boards and other components. From the temperature rise resulting in a leak and fire elements. Dust absorbs moisture, corrosion. Electronic circuits within the display. Cause strange problems, despite the low dust, but the display is a risk that can not be predicted.
★ How to remove and avoid the hazards of dust?
First, auditors should in a clean environment, clean but the dust is widespread, so in addition to cleaning the environment. It should also be checked to the purchase or special cleaning should be used immediately after each cast dust cover. Usually clear the dust on the screen. Remember, fire closer inspection, you must display and the cable outlet and then with a soft dry cloth from the center of the screen without the use of alcohol and chemicals such as solving the problem of cleaning, the use of rough cloth. Paper of all kinds of products, wipe the screen and the liquid does not spray directly on the screen to prevent ingress of moisture into the display. Apart from outside the vehicle. But the brush. Small vacuum cleaner (Fig. 1) tend to remove the display of dust and dirt in the following cases. But try You Do not wipe off, water on the damp cloth. Wipe off any pressure because of the high performance. (Closed after the ignition coil can still be excess capacity). As the removal of dust must not ask to use professionals steal back open review. (If the monitor is not with the warranty period, open, as is for a problem not under warranty. Oh) to avoid adverse effects.
Fourth, the magnetic field factor.
★ causes the magnetic field and the risks which, if the test may occur or not.
Electromagnetic interference is a circuit or the environment may not appear at voltage and current. Supply of electromagnetic Disorders. Components, cable, connect the fan. Neon lights, lightning and static are television sets, refrigerators, fans and much more. Are round or other devices. As speakers are protected, or to close a phone or pager from the screen, both the availability of electricity and magnetism. Field, these devices produce electromagnetic interference in the course of time, the chaos ad
★ How to avoid the magnetic field?
Long-term exposure in a magnetic field or damage the screen can be magnetized. (Get up for breakfast and above all does not work. Demagnetization), it should be studied in places far away from other areas. Often under conditions that can often use the buttons. Demagnetization of the advertisement, but that should not be used again and again, it is not so hard, otherwise it will cause damage. monitor.Discount battery. JVC. GR - 1U battery
Fifthly, the temperature factor.
★ temperature affect what checks?
CRT is the display of the main sources of the heat. The high temperature in the work of the efficiency and lifespan will be significantly reduced, some cold. Cooperative joint can be caused by melting of the fall open results show an instability if the components are aging and may eventually lead to the display, as are caused to "stop", while in other parts. Subject to decay or burnt.
★ How thermal cooling of the screen?
Place the monitor around. Obtain sufficient Have room in order to "breathe". monitor in the summer, a condition to know that the best place to air-conditioned or fan blowing.
Sixth, the use preventive action.
1. Do not let what they put on a display. The display can avoid a cooling effect on the normal pages to falling Debris. Damage to equipment.
2. should move Do not forget the monitor cable and unplug the cable and connector and cable to be shut down to to prevent damage to the interfaces. Circuit components.
3 for operating the control knob to a slow and continuous display is not difficult to switch to heavy Damage to rotate the head to prevent.
4 Connect the power cord or check the cable is to be noted that the display problems in most of the poor or the environment are found from the screen when the color will result in bad contact. Or can not be reduced simultaneously. Bending-pin connector is not in a position to Content Check the hard disk does not affect the color or colors to show and can lead the folding and down screen problem is because if the pin can be made break the legs bend complicated.
5 Frequently simultaneously displaying such content can be installed on your computer, computer screen savers prevent phosphor Age
6 shows such as drawing too late to reduce the brightness of the display and focus the rays can not.
7 When the vibrating of the reason that most of the interference the external magnetic field, as the magnetic field caused by transformer low-frequency voltage is too high, too. This allows the screen immediately, which since the monitor high-pressure defense done show. In the high-pressure defense, you must immediately shut down, such as voltage stability after a few minutes in the boat back to work.
8 Although the display of adjust voltage to the relatively large size. But is because of the effects of high pressure components while. Damaged, it should still be used with the fuse socket be. If conditions should allow this UPS (uninterruptible power supply).
9, light brightness are reduced. (Right), can also cause the light bulb and the removal of phosphorus.
10 may be on the screen for radiation protection, mounted as in Fig. 5, the best option. Technology protection, protective conductor. Products with good quality can keep up. can increase 90% of electromagnetic radiation and the contrast of the screen to increase the contrast of the display. But also eliminate static electricity and light. Absorb UV light. So, not only. But to protect human health is still good shows. Battery replacement costs. PANASONIC. CGA - DU21 Battery
Having said that, "Page" of maintenance, it looks very complicated. In fact, a great interest in the "front" of us as long as it is normal. Hard to be relieved of duties.
