Display flashing black
[Users questions | Browse:62 | Favorites]
Users questions: Recently found my LG2234 LCD monitor has the phenomenon of the black flash as the monitor and open it at customs. However, facing the monitor with a fan blowing, this situation is basically not appear. In the case of not blowing my hand feeling the temperature of the display is normal! No special heating. So I do not understand what is the problem? 77 Check your 7777 resolution and refresh rate settings are appropriate to the monitor to use on another host, if the fault disappears, the fault may be the graphics card. If the problem persists, you may monitor their own fault or the fault monitor interface cable. Check the monitor power key The interface cable is broken or bent metal pins, and if not, simply to change the display of a new cable and try again. 1, power line or data line problem. 2, the display tube of the problem (recommended repair). 3, the graphics card or graphics driver problem (for a try or upgrade the graphics card driver to try.) Graphics Fault diagnosis is as follows (1) bad video card failure: usually caused by bad video card can not be switched on and the sound of an alarm system instability or crashes and other failures. Poor contact caused by graphics card finger was mainly due to oxidation, dust, or poor quality of the chassis bezel graphics problems. The finger is oxidized Caused by poor contact, you can wipe the finger to address the use of rubber; for poor contact caused by dust, the dust cleared immediately after the general solution; for hardware quality due to poor contact, usually by replacing method to detect, generally used to replace the graphics card to solve the ; for problems caused by exposure to the chassis bezel poor Usually can not be fully inserted into the graphics card slot, replace the chassis can be used to exclude. (2) compatibility: compatibility failures can cause the computer will not boot normally and the alarm sound, system instability and crashes, or unusual noise so the screen malfunction. Graphics card compatibility failures are generally installed in the computer or just upgrade Later, more common in the motherboard and graphics card or motherboard is not compatible with the card slot can not be fully finger touch. Graphics card compatibility fault detection method commonly used replacement is generally used to replace the graphics card to troubleshoot. (3) graphics parts breakdowns: graphics components, failure usually results in damage to the computer can not boot, the Department of Unstable system crashes, Huaping and other symptoms. Damage generally include graphics components, graphics chip damage, the graphics card BIOS is damaged, corrupted memory, video card capacitors or FET, damage and other damage. Graphics components for the general need to carefully measure the damage to the fault in the circuit card to determine the damage to the various signal components To find the damaged components, the replacement can be. (4) graphics card overheating fault: the graphics chip at work will have a lot of heat, thus the need for better heat dissipation, damage will result if the cooling fan overheating graphics card does not work. Overheating graphics card failure will cause system instability are usually dead Machine, Huaping other symptoms. Occur if you replace the graphics card fan to overheat. (5) graphics driver failure: the graphics driver failure will cause system instability and crashes often, Huaping, text, images and other graphics card is not completely malfunction. Graphics driver graphics driver failure include loss of significant Card driver is not compatible with the system, the graphics card driver is corrupted, can not install the graphics drivers and so on. For the graphics card driver failures are generally the first to enter the "Device Manager" to see if there are graphics drivers, if not, re-install. If there is, but the graphics card driver on a "!", Indicating Graphics card driver is not installed, the driver version does not, the driver is not compatible with the system and so on. Remove the graphics drivers usually re-install, if after the installation there is "!", You can download the latest drivers installed. If you can not install the graphics driver, usually a driver problem or a registry Problem. (6) CMOS setup problem: CMOS setting failure was due to set the CMOS option to display the relevant error caused failure. CMOS settings common failures include: integrated graphics motherboard, CMOS settings in the mask option card error; such as "AGPDriving Control "option set incorrectly (usually should be" AUTO ")," AGPApertureSize "option to set the error:" FASTWriteSupported "option set errors. CMOS setting error tends to be used to load default BIOS values revised Change can be. (7) graphics card overclocking issues: the problem is the graphics card overclocking when used to improve the speed of graphics cards, graphics cards operating frequency increase caused by computer failures. Problems, it can be restored to factory default frequency settings. If you need to drive, it is recommended to install Driver Genius 2008, after installation, , Using its automatic update driver feature that will automatically download and install the latest version of drivers, including network cards, sound cards, video cards, USB, etc., without having to find and install a hard time. Download and install, open the driver wizard will automatically detect your computer's hardware information, testing has been completed, click on "Update Driver" button, switch interface, and then click the "automatically installed", then click the bottom right corner of the "Start Update" button.
