All televisions now produced are digital.
All televisions currently produced have an installed digital tuner. This is because all broadcast signals are digital, forcing older analog sets to be connected with a digital to analog converter box. Regardless of how you are receiving programming on your digital television, you may run into problems with the audio or picture. When this occurs there are a few specific areas you are able to inspect on the television in order to determine what is causing the problems.
Instructions
1. Power down the television, and disconnect it from the electrical outlet. This performs a hard reset of the internal hardware, allowing everything to boot up fresh (you do not lose your system settings performing this). After a few minutes, power the TV back on and any electrical or hardware issues you encountered are now corrected.
2. Inspect the connection running from the digital TV to the hardware hooked up to it. If the cables are not fully inserted into the connection ports, the audio and video signals are lost. Also look over the actual cable for damage, such as cuts in the cable. If the cable is damaged, you must replace it.
3. Select a different video input if you experiencing problems with one of the video connections. If the second input functions correctly, you know the problem is with the connected hardware, not the television. If the inputs are damaged on the TV, you must take the TV into a local repair shop to correct the problem.
4. Move signal-based devices (telephones, radios and Bluetooth equipment) away from the TV if the set uses an antenna. These devices often cause interference with the television, causing distortion in the audio and video signals.
