An LCD TV is a flat-screen TV alternative that features Liquid Crystal Display technology to power its screen. LCD TVs can possess a number of common problems that can be tested and troubleshooted, sans the use of any complex tools and without the need for an existing body of knowledge concerning television operation and repair. Coaxial cable connection issues, receiver box hook up errors, video input miscalculations, and screen display irregularities can all be tested and remedied in short order.
Instructions
1.Check the power indicator light on the front face of your LCD TV. This is the simplest possible problem, as you may need to reconnect a disconnected power cable. Ensure your projection TV's power cable is secure within the wall outlet.2.Test the audio/video connections between the LCD TV and the cable or satellite receiver box. Your LCD TV will have shipped with an audio/video cable that has two sets of colored prongs, one on each end of the cable. You will want to ensure that these prongs are synced color-wise with the matching audio/video port sets on the back of your projection TV and the back of your cable/satellite receiver. One set of prongs will go into each set of ports. If the colors are mismatched at any point, switch the prongs and ports up and turn on your LCD TV to test the audio/video once more.
3.Test the video inputs provided by your LCD TV. It is possible your LCD TV has the wrong video input selected. You may check this by cycling through the video inputs using the "Video Input" button on the front of the projection TV, or the "Input" button located on your TV's remote. Continue to cycle through the inputs until you land on the one dedicated to your cable or satellite programming. This will restore audio and video to your TV if you were lacking it previously.
4.Ensure the coaxial cable that ships with the LCD TV is properly connected to your equipment. The coaxial cable will be connected and extend out of the cable wall outlet in your home or office that is nearest to your LCD TV if you are utilizing cable service. If you are utilizing satellite service, this coaxial cable will run down from the satellite dish outside.
5.Ensure the other end of the coaxial cable is plugged into the "ANT IN" port on the back of the satellite or cable receiver. If this cable is at all loose from this connection point, it will result in a degradation of signal. Make sure the coaxial cable is tightened into this "ANT IN" port by gently twisting the metal band on the coaxial cable's plug to the right. Test the coaxial cable connection further by wiggling the cable within the port and seeing if this results in picture degradation. If it does, further tighten the cable as described.
6.Check to see if there are any high-powered devices such as computers that are in close proximity to your LCD TV. These can create electronic interference that can cause picture display errors on your TV. Move these electronics away from your TV to resolve the issue.
