LG TVs are available with plasma, LCD and LED screens. The TVs offer an array of video inputs, such as HDMI, component, composite and S-video, and optical and standard audio output jacks for connecting external devices. If you are experiencing screen problems with your LG TV try resolving the problems through troubleshooting techniques before visiting a repair shop or sending the TV back to the manufacturer.
Horizontal or Vertical Bars, or Shaking Picture
Turn off electronic devices that are not being used and are near your LG TV. For example, unused gaming consoles, Blu-ray players, DVD players or cable receivers are all examples of devices that could emit an electrical signal that can cause a problem with the TV's picture. Alternatively, if the device you want to watch is the device that you feel is causing the problem move the device as far away from the TV as you reasonably can. Also remove cell phones, radios, MP3 players, lamps and similar electronic equipment away from the TV.
No Color or Bad Color
Adjust the color on your LG TV to manipulate the intensity of the colors that appear on the TV. Press the "Home" button on the remote control that came with the TV and select "Picture" using the arrow buttons. Press "Enter." Press the "Down" arrow to highlight "Color" and press the "Left" arrow to decrease the intensity of colors on the screen or press the "Right" arrow to increase the intensity of colors on the screen. Setting the color to "0" removes all color and the TV will output images in black and white.
High Speed HDMI
LG TVs have problems with some HDMI cables and often require the use of a high speed HDMI cable when connecting external devices. If you are connecting your external device using a standard HDMI cable and you experience a display that flickers in and out or does not display, try using a high speed HDMI cable to connect the external device to the TV.
PC Display Problems on LG
The outputted image associated with a PC that is connected to an LG TV can appear distorted, cut off or have black lines appear on the sides of the TV if the PC resolution is not compatible with the PC resolutions supported by the TV or if the TV is not set up appropriately. You can automatically configure the LG TV to display the PC's image with the best possible set up by pressing the "Home" button on the remote and then selecting "Picture." Select "Screen" and select "Auto Config." Select "Yes" to initiate the auto configuration. The LG TV may blink for a few seconds before the display is optimized.
