- Q:The LCD display is dark
- The circuit of the screen is out of order. Fix the screen and go. The switch on the screen is useless. The internal circuit problem.
- Q:LCD display lights are not what is going on, the screen is not bright
- Change the host to try the monitor, if the good is the computer graphics card problem, if bad, it may be the monitor internal problems, this master came
- Q:LCD power switch after opening
- According to my maintenance of liquid crystal, there are several situations: 1, generally high voltage protection, not very serious kind of high voltage protection, you can manage the chip through the protection of the foot grounding. 2, the power on the board of a capacitor explosive pulp or drum bag phenomenon, replaced on the OK. The bad performance of the 3, one of the high voltage coil power supply board, now the general case is directly to the general high pressure, the poor performance of the lamp light a few seconds can be the perfect solution, because the general pressure did not set up the general protection. 4, if a few seconds feel bright screen than the normal use of dark words, there may be a bad performance caused by the bright lamp seconds phenomenon, direct replacement of lamp can be solved, or the third point is that the change of general pressure can be solved. These are generally more familiar with the point, the circuit principle can go to get, otherwise there is an electric shock risk, because the power on the board is energized with high-voltage, without electricity, the case is without high pressure. General take outside repair one hundred yuan less than normal, ha ha, hope to say these can help you.
- Q:Liquid crystal display, the word is too black, color is too heavy, how to adjust? Thank you
- Don't listen to the above two, you do not know the display driver not installed, but no security can also be adjusted, the desktop blank, right click, a display, if you click No, you must install and display graphics driver, click on the color graphics are set and display after entering color set, you can follow your favorite graphics to adjust, color correction, gray adjustment can change the depth of color.
- Q:How to distinguish between LED and LCD
- Big brother, I guess you've been cheated, because LED, like the big brand LG, is easy to tell, and the thin one is that Samsung's LED are all EX models (with exceptions), or very thin, with no vents at the back.The best way to distinguish is the one on the LCD display monitor together with you on the point, more than half an hour at the temperature of LCD LED is very hot, warm, if the temperature is almost, you cheated,And what's your brand? Can Baidu you monitor the brand's official website, to see if the model is not, can not get it? You are estimated to be less than 2500 of the machine, petty gains now.
- Q:Liquid crystal display without glare
- Being a programmer or software, staring at a monitor for a long time can make eyes tired. Therefore, the quality of the monitor is very important to protect the health of the eyes of programmers.Spectral missing, blue light, strobe and other display problems, causing LED display damage to the human eye is very serious!The LED monitor became the famous ophthalmology GO! Even if you want to lower the brightness and contrast. Just adjusting the display control circuitry does not compensate for the inherent defects of the LED backlight. Since LED is so bad, why do most display makers want to promote LED in a big way? Just because the cost of LED is low, it can create more profits for them! As for LED's eye damage, it's not what they care about.Therefore, here still have to recommend the CCFL backlight technology has been used for years to everybody, although no LED low power CCFL, although no LED high brightness CCFL, although there is no CCFL LED high contrast, but CCFL than LED damage to the human eye is much smaller.Although the IPS panel shows excellent results, it also has the biggest eye damage to the LCD panel. The TN and VA panels do little damage to the eye. Recommend general office, home, and programmer users to select TN panels; games, movies, graphic designs, and users choose to display better VA panels.Display control circuit design strength of the most powerful brands are 4, namely: Zhuo Zhuo, rice mountain, NEC, MITSUBISHI. These four are the top in the field of display, so it's important for the health of the computer's eyes.
- Q:Maintenance of liquid crystal display
- Daily maintenance points:1 、 liquid crystal display for a long time do not use, please turn off the power or set the host for power-saving mode.2, as long as possible to reduce the use of bright white screen for a long time, these two points can slow down the aging of the tube, and extend the service life of the monitor.3. Keep the storage and use environment clean and correctly clean the screen surface.4, away from the high temperature and humidity environment.5, no liquid upon screen and machine.6, strictly prohibit extrusion impact screen surface.7, avoid unnecessary vibration.8, do not disassemble and disassemble.
- Q:LCD displays have many black spots
- Try the following steps to confirm the type of the black spot:1) restore the display to factory settings (via the OSD menu on the display)2) check that the video cable is plugged inIf the black spot disappears after the operation of the above step, the black spot is proved to be the fault shown by the monitor; it has been repaired; if not disappeared, continue the following steps.3) set the desktop to full white to make sure the macula is still there4) reinstall or update the video card driver to the latest versionIf the black spot disappears after the operation of the above step, it is proved that the black spot is caused by a system or a video card drive; if not disappeared, the hardware of the display is found to be faulty and should be repaired.
- Q:Is the LCD screen dimmed?
- The trouble of LCD should be that the power supply of the power supply circuit of the lamp tube is reduced, and the brightness is decreased sharply;There are two reasons for the power reduction of the lamp supply circuit:1 、 the load capacity of the monitor main power supply is reduced; the filter capacitor and diode in the rectifier filter circuit are not good, or the gain of the power switch tube is low (usually the bias resistance is changed);2 、 the fault of the lamp supply circuit;Landlord can borrow other people with the same type of power to try, see if the problem can be solved;If not only repair.
- Q:Can the liquid crystal display of notebook computer be wiped directly with wet cloth?
- No way! With a dry cotton cloth, water will make the screen flower
