Purchasing a big screen TV is a major investment. You will naturally want to protect this investment, and that means making sure the device runs properly and receives any repairs it needs in a timely manner. Repairs might require a professional, but in many cases, personal troubleshooting and adjustments can alleviate your big screen TV woes and save you money.
Instructions
1. Plug in your TV. Make sure the connections are all sound and secure. For instance, check for loose cables that come out of the wall outlet or surge protector, or that are located at the back of the television. Make all of these connections snug.
2. Check your satellite or cable box. Check the back of these boxes and make sure the AV (audio/video) cables are all in place tightly and plugged into the correct corresponding color-coded spots. The AV cables in a standard setup are three-pronged with yellow, white and red plugs. Make sure all are plugged into the correct ports on the back of your cable or satellite box.
3. Check the video input options on your big screen TV. Do you have the right video input selected? Bear in mind that each outside peripheral, such as a video game system or DVD player, will use a different video input to operate on your TV correctly. If you switched the input to play one of these devices, you might have neglected to switch the input back. So, instead of your cable or satellite coming through, you will find you still have the input on for your Xbox. On your remote, locate the "Input" button and depress it until your television feed pops back up.
4. Check the front of your big screen TV for any irregularities. TVs sometimes have a magnetization problem, which will result in blotches on the front of the display. To fix this problem, use a magnetic coil and wave it slowly over every portion of the front of your big screen TV display. Check then to see if the blotches are gone on your display. If so, your TV has become demagnetized.
5. Wiggle the coaxial cable to fix any "snow" problems on the display of your television. The coaxial cable comes out of the back of your big screen TV and can be a problem, depending on your particular setup. Wiggling the cable and pushing it firmly, but gently into the port on the back of your TV might alleviate your display problems.
