How to fix dotted lines or stripes on Insignia NS-28E200NA14 screen?

If you see dotted lines or stripes on your Insignia LED TV screen, make sure the antenna or cable TV is connected correctly and securely. If you are using an antenna, the digital channel signal may be low, use a highly directional outdoor antenna or set-top antenna with a built-in amplifier. Make sure that the video cables are connected securely to your TV. The video cable(s) you are using may be bad, try a new set. Other devices (for example, a surround sound receiver, external speakers, fans, or hair dryers) may be interfering with your TV. Try turning off one device at a time to determine which device is causing interference. After you have determined which device is causing interference, move it further from the TV to eliminate the interference.
