Symptoms and Recommended Actions

Note

•A LCD Display recreates visual signals received from the computer. Therefore, if there is a problem with the computer or the video card, this can cause the LCD Display to become blank, have poor coloring, become noisy, and video mode not supported, etc. In this case, first check the source of the problem, and then contact a Service Center or your dealer.

1)Check if the power cord and the video cables are properly connected to the computer.

2)Check if the computer beeps more than 3 times when booting.

(If it does, request an a service for the main board of the computer.)

3)If you installed a new video card or if you assembled the PC, check if you installed the Adaptor(video).

4)Check if the scanning ratio of the video screen is set to between 50 Hz ~ 85 Hz. (Do not exceed 60Hz when using the maximum resolution.)

5)If you have problems in installing the Adaptor (video) driver, boot the computer in Safe Mode, remove the Display Adaptor in the "Control Panel, System, Device Administrator" and then reboot the computer to reinstall the Adaptor (video) driver.
