Why are there dotted lines or stripes on my Insignia TV screen?

If your Insignia TV displays dotted lines or stripes on the screen, ensure the antenna or cable TV is securely connected. If you're using an antenna, check the digital channel signal strength and consider using a better antenna. Also, ensure the video cables are correctly connected and try replacing them if necessary. Other devices may be interfering with your TV. Try turning off one device at a time to determine which device is causing interference and move it further from the TV to eliminate the interference.
