LCD monitor maintenance skills
1, to avoid screen burn inside
CRT monitors can be as long-term work and burn, also the case for the LCD, so be sure to note that if, when not in use, be sure to turn off the monitor, or reduce the display brightness of the display, or a long time, can lead to burn out or the internal aging. This event is permanently damaged and can not be undone. In addition, if a fixed time to display the contents of a row, there are some LCD pixels can cause overheating, which causes internal burns.
2 to keep the humidity
General humidity of 30% to 80%, and the monitor can work, but once the indoor humidity above 80%, the monitor will produce condensation inside. Its internal coils for power transformers and other easy to produce leakage after wet, or even short-circuit may cause the connection; and display area are easy to produce high-pressure discharges; machine components, rust, corrosion, serious cause circuit short-circuit boards. Therefore, LCD displays must pay attention to moisture, long time do not display, you can work regularly power for some time, so that the heat generated when the monitor will work inside the moisture driven out.
Also, do not make things any nature with moisture into the battery Dell Vostro A860 LCD. Found in mist, with a soft cloth to gently wipe before you can turn on the power. If the wetlands were already into the LCD, the LCD must be placed on a warmer place, so that when water is evaporated and organic compounds. Containing moisture LCD power, LCD electrodes can lead to corrosion, and cause permanent damage.
3, properly clean the screen surface
If you find that the display surface stains, use a soft cloth moistened with a little water and gently wipe, do not sprinkle water directly to the display surface, the water to enter the LCD screen will lead to short-circuit.
4, to avoid vibration
LCD screen is very fragile, so to avoid strong shock and vibration, HP Laptop ac adapter LCD glass, and contains a lot of sensitive electrical components, fell to the floor, or strongly against other similar LCD screens and cause damage to other units. Also careful not to put pressure on the LCD display surface.
5, Do not dismantle LCD
One rule is: do not you remove LCD. Closed for a long time even after the components of the CFL backlight inverter is still possible with a high voltage of about 1000V, this pressure can lead to serious personal injury. So do not you ever attempt to remove or change the LCD screen, so as not to experience high pressure. Unauthorized repairs and changes will lead to temporary or even permanent display does not work. So it is in your hands and feet when the restless, do not move delicate and dangerous Battery HP Pavilion dv7 LCD!
CRT monitor maintenance skills
1, anti-high temperature:
As a large CRT monitor heat, high temperature will considerably shorten the life of the display, other components also accelerated aging, Mody CRT monitors placed in a ventilated environment is a good place, the best place to monitor air-conditioned room, or electric fan blowing, to extend the life of the display.
2, moisture:
Humidity on the life of the display is very large, best to keep the humidity at 30% -80%, and when the humidity is over 80% of the time, will produce condensation inside the display, power transformers and other coils moisture resulting from leakage, coil in the case of high humidity, easy to produce electrical discharges, other components inside the machine may also damp rust, corrosion, serious cause a short circuit board. When the humidity is below 30% of the time, will display some of the mechanical friction generated static electricity, the internal components, especially the possibility of damage by Battery SONY VGP-BPS18 static electricity ignition coil increases, so do not display a long period of time to work on a regular basis will power the machine drive to moisture.
3, anti-glare:
Light exposure, the body easily aging yellow, CRT phosphor accelerated aging and reduce the luminous efficiency, lead had to use the display’s brightness and contrast adjustment are very high, the results of further accelerate and phosphor picture tube filament aging, shortened life of the display. Therefore, do not put the monitor placed in strong sunlight or light must pass through the place, it is best placed in sunlight the display weak or no light areas; or in the light must pass through the place, dark pieces of cloth hanging reduce the light intensity.
4, the dust:
As the high pressure inside the CRT monitor (l0kV ~ 30kV) easily attract dust particles in the air, the printed circuit board inside the display will be a lot of dust absorption, affecting the cooling of electronic components, high temperature burn will have leakage phenomenon components, and the dust can absorb moisture, corrosion, electronic circuits inside the monitor. Therefore, usually should be used to clean the monitor placed in a clean environment, should be made to display a battery IBM ThinkPad T60 special dust cover after each use with a dust cover to be cast in a timely manner.
5, magnetic:
CRT monitor long-term exposure may be magnetized in a magnetic field or damaged. Television, fluorescent lights, refrigerators, electric fans and other household appliances around the magnetic field, electromagnetic over color screen will display distortion, usually used when the monitor in a place far away from other fields, use the monitor on a regular basis degaussing degaussing button.
6, other:
a. When moving the monitor, power cord and signal cables to unplug and plug the power cord and signal cable should be shut down.
b. in regulating the function of the display panel knob, to slowly and steadily, not a hard switch to turn fierce, to prevent damage to the knob.
c. monitor should be inserted in the socket with a fuse, preferably with an uninterruptible power supply.
d. Do not stack debris on the display.
e, display the same content as regular time, preferably using the screen saver.
f, the screen suddenly no display may be line frequency is too low, too high voltage monitor high-voltage protection will occur, must immediately shut down, such as voltage stability after a few minutes to boot to work again.
g, use, appropriate to reduce the brightness of the filament and phosphor slow down the speed of aging, should not use too high a refresh rate to extend the battery Sony VGP-BPS13 life of the display.
h, a radiation protection devices installed, good quality, can prevent over 90% of electromagnetic radiation, and can enhance the contrast of the display, enhanced clarity of display, but also eliminate static electricity and glare, absorb UV light, not only to protect human health, display is also good.
i, do not smoke in front of the display of cigarette tar in the coating material will be on display there are injuries.
j, do not often switch machines, switch high-voltage changes on the life of the display has a great influence.
k, do not often touch the screen with your fingers.
7 Clean:
The outside color display and maintenance of the machine is divided into two parts. Clean the outside surface of the main display screen is clean, machine cleaning, you need to open the display case.
a, the outside cleaning
Color HP COMPAQ Battery display screen surface glare, anti-static coated with a layer of very thin coating of chemical substances, usually clear the dust on the display screen, remember to be off the monitor and disconnect the power cord and signal cable show lines, soft dry cloth to wipe out from the center of the screen, the method should wipe the screen gently wipe the inner ring radially outward, if the screen surface is dirty, you can use a small amount of water absorbent cotton or lens paper moist wipe, do not use alcohol a chemical cleaning solution. In addition to the display outside, but also commonly used in the display case on the brush often erase the dust and dirt, try not to use water on a damp cloth wipe.
b, the machine clean
Its internal dust removal, must ask professionals to operate, do not open the display cover without permission, display if the power is not long before, in the graphite tube and high-pressure front will have a residual pressure on the cap, then the pressure to provide energy enough to hurt, please use the thick rubber wire shorted edge of the display circuit board inside the metal plate and high-pressure apparatus, the release of residual charge, in order to avoid serious consequences. To monitor the internal dust off the monitor when the first power, under the display with a Phillips screwdriver four corners of the screws, remove the display back cover. Paintbrush for display before cleaning, dust is a key part of CRT, and Battery Dell LATITUDE D800 CRT rear coil circuit boards. Another glass tube devices, carefully damage, depending on the display board put the tail pipe inserted in the seat tube, and some video amplifier circuit tail pipe plug and seat tube bonded together, forced Banxia may damage the tubes, please operation attention.
8. Menu settings
① Brightness: General set 60-80. Easily cause eye fatigue is too bright, but also use the premature aging of phosphors.
② Contrast: generally set at 80-100.
③ refresh rate: if less than 70HZ, will feel the flicker, set the computer’s refresh rate to increase. Refresh rate of the field frequency, refers to the number of times per second the screen repeatedly drawn to HZ as a unit. The higher refresh rate, the more stable the screen display, the less light flashes. Most people’s eyes more than 75HZ refresh rate for the basic feeling of not blinking, 85HZ is no light flashes above, so the association will 85HZ VESA international video developed for the flicker-free progressive scan standard. Ordinary color TV’s refresh rate is only 50HZ, currently the lowest in the computer output to the monitor refresh rate is 60HZ, 85HZ or 75HZ suggest that you use the refresh rate. Do not set the monitor refresh rate limits the maximum refresh rate should be slightly lower than the maximum of a grade. Because when the Compaq laptop battery display work in the limit state, the circuit elements prone to damage caused by aging.
