• Make sure the pins on the video cable are not damaged or bent.
• Verify that the video cable(HD-15 )is securely connected to the video card in the computer.
• If the monitor is using 5BNC to VGA Cable, Please Verify that the video cable(5 BNC to VGA Cable)is connected to monitor correctly.
• If the monitor is in power saving mode, move your mouse or strike any key on your keyboard to recover video. ( Indicator LED light change to Orange Color, If monitor is on power saving mode)
• Try a standard VGA driver in Windows to verify the consistency of the problem. If the problem does not occur with the Windows standard VGA driver, then there may be something wrong with the video card’s configuration or the card may be defective. For Macintosh users, make sure that you have the correct dip switch settings for your monitor.

No Power

• Make sure the power cord is securely connected to the monitor and power source. Check the power source with another device such as a radio to make sure that the monitor is receiving voltage.
• If the monitor is plugged into a power strip, try connecting to a dedicated wall outlet. For pulsating image, remove any electronic devices* at least 3-4 feet away from the monitor.
• For high-pitched noises, try plugging the monitor into a different power outlet.
• If there is a horizontal line scrolling from top to bottom of the screen, try the monitor with another computer and power source. The monitor is not receiving enough power input.

• Make sure the pins on the video cable are not damaged or bent.
• Verify the video cable is securely connected to the video card in the computer.
• If the monitor is using 5BNC to VGA Cable, Please Verify that the video cable(5 BNC to VGA Cable)is connected to monitor correctly.
• Be sure that all electronic devices* are at least 3-4 feet away from the monitor.
• If your monitor is equipped with a manual degauss function, try to degauss the monitor to see if the color dissipates. If this function is not available, then turn the monitor off, wait about 15 minutes, and then turn the monitor back on. This will cause an automatic degauss to occur.
• Monitor’s performance May be affected by the Earth’s magnetic field. Try rotating the monitor to different directions to improve. Try move the monitor to different location.
• Test the monitor on a different computer to isolate the problem further.
• Check carefully on bezel of the screen to see any psychical damage, cracks and dents.
• Call (888) 785-7288 immediately, if there is shipping damage on side of bezel.

• Make sure the refresh rate is at 75Hz or above. Verify the problem at all possible resolutions and refresh rates.
• Be sure that all electronic devices* are at least 3-4 feet away from the monitor.
  If your monitor is near a wall, any transformers or power lines inside the wall may cause the monitor to flicker or jitters.
• Try a standard VGA driver in Windows to verify the consistency of the problem. If the problem does not occur with the Windows standard VGA driver, then there may be something wrong with the video card’s configuration or the card may be defective.
• Test the monitor on a different computer system in a different location.
• Make sure the power cable is plugged directly into the wall outlet or surge protector. Do not connect to a device that might share multiple connections. The power fluctuation may cause ripples, jitters, or flashes on the screen.

Tilted Screen:

• Use your tilt control adjustment, if available. If this feature is not available, then adjust the image’s lower edge aligned to the bezel. Individually measure the height of the image’s left edge and right edge. The difference of 1/12” or less would be considered within specification.
• Turn the monitor to face different directions. The monitor is recommended to face East for optimum display.
• Any non-square shape (trapezoid or parallelogram), pincushion, barrel, or image shifted:
• Use the controls provided either on the front panel of the monitor or through your OnView Controls, if available.
• Verify the problem at all resolutions. If the problem does not occur at all resolutions, then it is usually an indication of a video card problem.
• Try a standard VGA driver in Windows to verify the consistency of the problem. If the problem does not occur with the Windows standard VGA driver, then there may be something wrong with the video card’s configuration or the card may be defective.
• If the distortion is not evident when tested on a different computer, the video card you are using may be defective. Please consult with your video card manufacturer for further assistance.

• Make sure the pins on the video cable are not bent or damaged.
• Make sure there are no extension cables or switch boxes attached to the monitor.
• Verify that you have the proper drivers installed for the video card.
• Verify the problem at all possible resolutions and refresh rates.
• Make sure the refresh rate does not exceed maximum value for any resolution.
• If your monitor is equipped with Convergence control, adjusting this will improve the clarity of the text. All Trinitron and Diamondtron CRT have are equipped with Convergence Control.(You can adjust Vertical and Horizontal convergence)
• Test the monitor on a different computer.
• Contrast is recommended to be set at a higher range while the brightness should be set at middle range. This helps to increase the text clarity while reducing the bright background.
• If your monitor is equipped with moire control, adjusting this may improve the clarity of the text. Moire is a wavy distortion pattern caused by interference between the dot pitch of the CRT and the picture signal. The pattern may vary depending on the screen amplitude, contrast, brightness, and other characteristics of the input signal.
• Monitor’s performance may be affected by the Earth’s magnetic field. Try rotating the monitor to different directions to improve Misconvergence.
• Most video cards offer a software utility that changes the frequencies and sync polarities for all resolutions. If the setup does not match with the monitor’s characteristics, an incorrect signal may be displayed on the screen. Sometimes, the image may also appear blurry.

• When an extension cable is used, the improper shielding of the video cable will cause a shadowing or ghosting effect. This improper shielding causes a mismatch of the input impedance between the video card, the video cable, and the monitor. In addition, if using a switch box or low quality cable, these two items will also cause signal degradation. Check the video cable to make sure all the pins are in good condition. Test the monitor on a different computer.

• Aperture-grille monitors such as Sony Trinitron, Mitsubishi Diamondtron and ViewSonic SonicTron use a technology called aperture-grille that uses alternating red, green and blue vertical phosphor stripes instead of dot triangles to yield sharper images and brighter colors. Aperture-grille technology uses 1, 2 or 3 (depending on monitor size) horizontal stabilizing wires which can be seen as fine lines across the screen on bright images. The visible horizontal stabilizing wires are a normal characteristic of all aperture-grille monitors.
