Facing TV Problems? Ask a TV Technician.
Hello, Who is your Cable/SAT provider please (for example: Comcast, Charter, DISH, etc.)?
Thank you. Offhand "Code800" does not pull up under any searches. What is the exact, specific message you're seeing on the two TV's repeated every 10 minutes please?
Previous expert has opted out, on the third TV that does not present the banner is that connected to comcast too?
