Why are there lines on my Insignia NS-32E321A13 LED TV screen?

If your Insignia LED TV displays dotted lines or stripes on the screen, ensure the antenna or cable TV is connected correctly and securely. If you're using an antenna, the digital channel signal may be low, so adjust the antenna or use a more powerful one with a built-in amplifier. Also, make sure the video cables are securely connected, or try a new set. Other devices like surround sound receivers, external speakers, fans, or hair dryers may be causing interference. Try turning them off one by one to identify the source and move it further away from the TV.
