Fixing a TV is a multistep process that requires a lot of troubleshooting. Different kinds of TVs work in different ways, but there are number of basic troubleshooting steps and fixes that can alleviate a problem with your television. Even if you are not a professional, there are steps you can take to fix your TV and enjoy your living room entertainment again in no time.
Instructions
1. Check the cable connections on your TV. Make sure the power cable is not loose from the power outlet. If your TV uses a coaxial cable, wiggle this cable and make sure it is plugged in tightly. Otherwise, your television feed will suffer, appearing to have "snow" (white static) on the display.
2. Check the connections from the television to the cable box or satellite receiver, whichever is applicable for your situation. Look at the A/V (audio/video) cables. These are the red, yellow and white cables that plug into the back of your television and the back of the cable box/satellite receiver. There are sockets for these A/V cables on the back of each device. These sockets are color-coded for the cables, and are red, yellow and white themselves. Make sure the cables are in the correct sockets, and that none are switched around.
3. Check the video input on your television. You may have the wrong input selected for the TV, and this would explain why your television feed or other media (DVD, etc.) is not being displayed visually or audibly. It is common that a television's video input will be changed to accommodate an external device, such as a DVD player or video game system. Use the "Input" button on your TV's remote control (or on the face of the TV) to cycle back through the inputs and select the correct one.
4. Use a magnetic coil on your TV's display. If you have a rear-projection television, this step may apply. Sometimes, rear-projection TVs can become magnetized, but the use of a magnetic coil (see Resources below) can serve to demagnetize the TV and affect the display, which when magnetized will bear blotches and other irregularities. Take the coil and move it in slow circles about a half inch away from the TV's display. Cover the entire display with this movement with the coil. This should help eradicate the display blotches.
5. Check the display of your plasma television, if you have one. With these TVs, the display may be marred with a burned-in image if you leave an image on the screen for too long (a paused DVD or video game, for example). If this burn-in occurs, the TV will have to be replaced or sent back if under warranty.
