Why does my Insignia NS-24L240A13 have dotted lines or stripes?

If your Insignia LCD TV displays dotted lines or stripes, make sure that the antenna or cable TV and video cables are connected correctly and securely. If you are using an antenna, the digital channel signal may be low. If the signal strength is low, adjust the antenna or use a highly directional outdoor antenna or set-top antenna with a built-in amplifier. The video cable(s) you are using may be bad. Try a new set. Other devices 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.
