How To Fix A Glitchy TV Screen


Common Reasons for a Glitchy TV Screen

A glitchy TV screen can be frustrating, especially when you’re trying to enjoy your favorite shows or movies. There can be several reasons behind this issue, so it’s essential to identify the root cause to find an appropriate solution. Here, we’ll explore the common reasons why your TV screen might be glitchy.

1. Loose or Damaged Cable Connections: One of the primary causes of a glitchy TV screen is loose or damaged cable connections. Check the HDMI, AV, or coaxial cables connecting your TV to the cable/satellite box, streaming device, or gaming console. Ensure that they are securely plugged in and in good condition. Loose connections or frayed cables can interfere with the signal and result in a glitchy display.
