TV Repair Questions? Ask a TV Technician for Answers ASAP
Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
What is the Model Number of the tv?
What are you watching when it happens (what specific device and content)?
How do you get bbc (or other channels)?
Is there an aerial, cable/satellite box, basic coax feed, etc?
Okay this is either a signal/reception issue,
or a hardware defect in the tv.
Go into the samsung setup menu, under channels, and run the channel scan/search feature from there.
Use the samsung tv remote, press menu, settings, or setup.
