How to Repair an Analog TV
- 1). Check the cable connections for your analog TV. If your power cord has become detached, make sure you plug it back in securely. A disconnected cable--while simple--is an error that will result in a completely inoperable analog TV.
- 2). Look over your coaxial cable. This is a highly important connection because if the coaxial cable is disconnected, or even loose, it will affect the quality of your analog TV's display. A loosened cable will cause the phenomenon commonly known as "snow" to appear on the display. Tighten the coaxial cable's connection into the "ANT IN" port on the back of your analog TV to avoid this problem.
- 3). Check your A/V cable connection. This cable dictates audio/video performance in your analog TV. The A/V cable has one set of six prongs on either end. There is one red, one yellow and one white prong in each set, and you will notice that there is one red, yellow and white A/V port both on the back of your analog TV and the back of your cable/satellite box (depending on which kind of service you are using). Ensure that the A/V prongs are plugged correctly into their color-matching A/V ports.
- 4). Reselect your video input. When using a connected device such as a DVD player, switching the analog TV's video input to receive audio and video for that device is necessary. However, you may have neglected to switch the video input back to the one that governs cable/satellite TV programming. If you are staring at a dark analog TV, try toggling back through the video inputs via the use of the "Input" button on your remote control. Continue to toggle through the video inputs until you hit the one associated with your TV programming.
- 5). Demagnetize your analog TV. When an electronic device is too closely placed near a TV's display, sometimes magnetization may occur that negatively affects the TV by causing blotches on the screen. Use a large magnetic coil to demagnetize the screen. This is performed by slowly waving the magnetic coil in front of the display in broad circles. This should alleviate the display blotches.
