Thanks for using the forums to get this issue with your nan's TV service, I am sorry she's having this problem on her Channel 5 recordings.
I understand you last posted about this around a week ago, were you able to chat with the faults team on her behalf about this?
The first thing we need to check is all the cables that connect to the TV and box, such as the HDMI, coax cable, power cable, splitter and the wall socket, can you let me know if tightening all of these helps?
The cables are all tight. My nan & grandad don't mess with the connections. They are instructed not to mess with anything on the v6. She's been watching it live since. Although she still records it aswell. We use a series link for recording the program. I'm not sure if it's the Internet causing the issue as it's plugged into the booster. As the rooter isn't in same room. The rooter is in my room above the living room 🤔.
Thanks for coming back to me, I have managed to look at our fault checker for your services and can see there is an SNR outage within your area at the moment which will be causing this issue. It has a fix date of 14th October but this is just an estimate, it could be sooner or later depending on what the engineers encounter. I am sorry for this inconvenience!
If the outage is fixed but you still experience this issue, please let me know on this thread and we'll continue to help 🙂
No recordings don't need the internet to play, they get stored in the box on a hard drive like Japitts mentioned. However, if there was an interruption on the channel whilst the program was being recorded, you may see or hear distortion on the playback.
