How to remove dotted lines from Insignia LCD TV screen?
- CCaroline RitterSep 10, 2025
If your Insignia LCD TV shows dotted lines or stripes on the screen, ensure the antenna or cable TV is securely connected. If using an antenna, a weak digital channel signal may be the issue; try adjusting the antenna or using a more powerful outdoor or set-top antenna with an amplifier. Check that the video cables are securely connected. The video cables themselves might be faulty, so try a new set. Other devices, like surround sound receivers or fans, could be causing interference; try turning them off one by one to identify the culprit and then move it further away from the TV.
