Hi @Amber771, thanks for your post here in the community and I'm sorry you're having issues with your TV.
As our VIP @Ernie_C has suggested, it is not an error code with our TV box so I do hope the Samsung forums can help you here.
If you do have Virgin Media broadband services though and the TV is detecting broadband faults, I'd advise trying to see if this is resolved too by connecting your TV to your Virgin Media Hub via an ethernet cable to see if things improve.
Many thanks
