- MMatthew VaughanSep 3, 2025
If dotted lines or stripes appear on your Insignia LED TV screen, try these solutions: * Ensure the antenna or cable TV is securely connected. * If using an antenna, check the digital channel signal strength. If it's low, adjust the antenna or use a directional outdoor or set-top antenna with an amplifier. * Make sure that the video cables are connected securely to your TV. * Try a new set of video cables. * 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.
