What causes my Roku TV screen to blink?
The blinking of your Roku TV screen can be attributed to various factors, with the most common being issues related to the HDMI connection. Loose or damaged cables can signal an interruption in the signal between your TV and external devices. Ensuring that your HDMI cables are securely connected and free from damage is a critical first step in troubleshooting this issue.
