Q: The display start blurring after a few minutes how to solve?
A: This may be the end of the outlet tube from the dust and damp or contaminated, it could be the picture tube aging (after using for a long time the problem) caused, according to the specific circumstances of “the right medicine.” For a wet or contaminated by dust, and if not very serious, clean the tube with alcohol outlet part of the tail can be solved. If the situation is serious, you need to replace the CRT rear outlet, and can go to the professional maintenance department to resolve the TV. For CRT aging, only replace the tube to completely solve the problem. If still under warranty, it is best to go first vendor (or vendors) to solve.
In addition, there is a reason related to the circuit display their poor quality electrolytic capacitors will cause this failure, but this well-known brands in the current display appears unlikely.
Q: When using the monitor wet weather, the display brightness is not normal how to solve?
A: This is due to moisture and dust inside the monitor pollution leakage phenomenon. COMPAQ 319411-001 Battery Leakage sites were concentrated in the tube end or high-pressure parts, especially high-voltage output part (line output transformer and the line output transistor area). Usually working in the dry weather display, in wet weather will produce electricity leakage problem, especially if the South Meiyu season, these are not normal screen brightness caused important reason. If it is not a problem with quality components, this is not normal will be maintained for some time, generally more than 20 minutes will be able to return to normal, because as the internal temperature monitor, the humidity decreases, the leakage also decreases, so the brightness will gradually return to normal. In such cases should be resolved quickly, or will cause local short circuit due to leakage, leading to display some of the surrounding high-voltage circuit damage. Eliminate leakage fault is not complicated, first open the display case, check the monitor internal components, the circuit board is a “moldy” (which is the main cause leakage), if it is found to be to find ways to give clearance. Also, remove all internal components with the accumulation of brush dust, because dust is also a leading cause of leakage. Using the above method, the problem can be solved most.
Q: how to solve the monitor produce color spots?
A: The display color spots appear (the stain) mainly due to magnetic interference, which is commonly referred to as being magnetized. The solution is to first check the monitor should be placed around it with a magnetic items, such as radios, televisions, mobile phones, speakers (especially the use of a powerful external magnetic speaker), etc., should these items away from the monitor . Also, note that the power cord around the display, data lines, as these will have a magnetic field, when near the monitor, it will have some adverse effects on the display. Solution is to move the monitor display the location and direction of change as much as possible to stay away from these wires: Secondly, we should use the monitor functions built-in degaussing degaussing, as long as the problem is not too serious usually can be resolved. If the result of these efforts there are still spots of color, it can only find manufacturers or vendors to help solve.
Q: Why is the display will flicker?
A: Display flicker is divided into two types, one is just the edge of flickering, the other is the screen is flickering. The former is due to self-monitor graphics card driver failure or caused by such failure to the monitor connected to another computer for testing, you can judge a glance. If the Windows 9X in the system can not correctly identify the monitor type, you can “control panel display — settings — advanced — — Monitor” in changing the type of monitor. For the graphics card driver problem exists Bug, you can download the new version of the driver to be addressed. The latter may be the MOTOROLA NTN7143 battery power outlet and indoor fluorescent lamps, fans, music centers and other electrical interference caused. Solution, the monitor away from sources of interference can be increased or appropriate to the monitor refresh rate flicker reduced to a minimum.
Q: How to prevent screen saver after the “crash” phenomenon?
A: In general, screen saver after the “crash” phenomenon has nothing to do with the screen saver. The problem is that access to screen saver is turned on while the “power saving setting.” Energy-saving setting allows the software off the monitor (monitor), the system is in sleep mode, and “death” phenomenon is in the system into hibernation after the. This phenomenon is divided into two situations: one is a fake “death” phenomenon, the performance when using the mouse, keyboard, the system wake-up, hard drives, monitors started, start the process should take some waiting time, patience and more anxious for the user within a few seconds did not see the system restore, it mistakenly thought it was a “crash”, in fact, as long as the patient will return later on, do not have to solve: the other is the true “death” phenomenon, mainly due to power management conflict, the motherboard CMOS settings in the Power Management Setup of the system from the hardware control of dormancy, but since Windows is software control of sleep, resulting in power management mode between hardware and software conflicts. Exclusion method is to enter the CMOS to the energy control all closed, use Windows power management can.
Q: Why is the monitor will issue a “click Ka” sound?
A: Some early production of the monitor is not used because of the internal switch automatically scan frequency, and using a mechanical switch scanning frequency, so this kind of switching the display when the machine will get a “carbazole Cameroon” sound. If the sound is not great, are generally normal. However, if the switching frequency while scanning, also will change the screen brightness, and issued a “flap” sound, it is not a normal phenomenon. Screen brightness changes and issued a “flap” sound, indicating that switching frequency leads to high-pressure scanning mutations, causing tube on the “high hat” at the ignition, wait until the brightness is stable, will not make any noise. This mostly occurred in the air is humid, too much dust inside the machine display, and buy a new Dell Inspiron e1505 Battery monitor there is no such problem.
Q: How can the power automatically turn off the monitor?
A: Under normal circumstances, automatically or manually turn off the monitor depending on monitor power installed. Simply put, if the monitor power plug directly into a power supply outlet, will not automatically turn off the display, only manually shut down. If you want to automatically turn off the monitor, you can monitor the power supply into an outlet on a case will be solved, but this requires the chassis with the power outlet, while the monitor cable before replacing a power supply can be achieved.
Q: how to solve the display refresh rate and set the refresh rate does not match the situation?
A: Generally speaking, in any resolution, refresh rate are exactly the same (using the default refresh rate). If a resolution (such as 1024X768) refresh rate set under the default refresh rate is not at the same time (can be normal operation), when in this mode, the resolution into a different resolution (eg 800X600) mode program, In 1024 X768 resolution, refresh rate is not set at the new refresh rate, but the default resolution in the 800X600 refresh rate. This is the display refresh rate and set the refresh rate of the reasons they do not match. The solution is, respectively, each resolution (800X600, 640X480) refresh rate are set under the required refresh rate, and then back to 1024X768 resolution, any resolution at this time re-entering the program mode will be the ideal resolution rate.
Q: Why is the display on the right will appear 5mm of the “indent” phenomenon?
A: This SONY np-qm91d battery phenomenon is not normally display quality problems, even if the replacement of a new display will not solve the problem. This phenomenon is mainly due to indent the thermal stability of the picture tube is not good cause, this phenomenon is more obvious for the flat panel display. The best flat screen monitors in general are lmm, most of them will in the 2mm, or even in serious cases to the individual 5mm. So buy the monitor, be sure to check in after 40 minutes warm-click the “indent” truly reflects the comparative degree of thermal stability to the display.
Q: How to solve the problem monitor color is not normal?
A: This question relates to two cases. One is the boot screen color is not normal, but use the color returned to normal after a period of time, such displays are a result of prolonged use of kinescope aging may go to the local repair service monitor, but it may not be repaired How much it costs to improve a lot, as the replacement of a new monitor. The other is the color screen after boot is not normal, and no matter how long and so can not return to normal color, this may be the monitor and graphics card are missing the connection between the plug pin (needle) or some needle bending cause a bad connection can check the monitor plug if there are problems. Note that the check is best to work with a monitor to compare the monitor connector plug if it is determined that there are problems, you can try to sell supplies to the computer store to purchase a replacement to plug their own. The time of purchase should also note that the shape of the monitor connector is fit to prevent the purchase can not be connected to the display.
Q: The “Huaping” how to do?
A: The display Huaping common symptoms of computer in the text mode of Huaping showed character confusion, graphics mode usually presents graphic stratification. Huaping phenomenon appears on the computer, we can use this method to deal with:
1. CANON nb-3l battery Display card conflict with the Chinese system, some cards with the Chinese system of conflict, which occurs when exiting the Chinese system Huaping, keystroke no reaction, similar to the crash, this time without the cursor in the case, from the keyboard “ModeC080″, Huaping can be solved the.
2. Improper display resolution is set Huaping in Win3.X resolution setting will be displayed with Win95/98 too high in the use of the screen may appear layered, jitter, and even black screen of death phenomenon. As long as the resolution is set to be normal values on it.
3．Bad graphics card master chip graphics card control chip cooling heat can also cause bad Huaping phenomenon, add cooling fans for the video card or improved graphics card cooling conditions, the problem will be solved.
4． Memory speed is too low when the display shows the speed of the memory is too low, and the host does not match the speed, the phenomenon may also appear Huaping, as long as the computer by setting the system CMOS or lower speed, or replacement of higher-speed display memory to avoid Huaping phenomenon.
5．Display memory corruption when the display memory is damaged, the system will start Huaping, the phenomenon of chaotic characters. As long as the replacement of display memory on it.
6．Because some viruses attack the virus can cause Huaping phenomenon. With anti-virus software antivirus virus in addition to killing the phenomenon disappeared after the Huaping.
Also, note that more attention to the graphics card and monitor compatibility issues.
Q: The monitor power, the power light is off, how do?
A: First check the power cord connecting the monitor connected, the power has power. Excluding the above reasons, the open display case, check the fuse is blown, if blown, replace it with the specifications available. Replaced, such as re-burning fuse, it should focus on examination of the power part of the rectifier filter circuit and power switch.
Q: Display power, the power light is off, and the machine issued a “creak” sound, why?
A: There is such a failure, that MOTOROLA GP340 battery displays a short circuit within the components, resulting in power overload. For such failure, should focus on checking lines of output tubes and peripheral circuits. In general, the monitor line output tubes were powered by 2SD series high-power transistor, as a result of the high voltage, high current state, the more easily damaged. If the line of the output tube is damaged, apply a similar argument with the model or replace the tube.
Q: The display is powered, the screen does not grating, what is the reason?
A: In this failure, they should first determine if the fuse blows, if the fuse is not blown, you should focus on examination of the power switch startup resistor and switch itself, as the two components if the problem will did not result in power output, scanning the circuit does not work, naturally, there is no grating.
Q: The display brightness is not enough, but the brightness adjustment knob does not work, how do?
A: In this case, there may be two reasons: First, adjust the brightness control potentiometer circuit or a problem, if necessary, can be replaced; the second is to use the monitor for too long, resulting in tube aging, if it is determined this is the case, you can adjust the line output transformer on the anode voltage, anode Sony VGP-BPS9 battery voltage will increase the number of appropriate, to enhance the brightness of the character.
