I am sorry to state the obvious here but did the place you purchased the TV not offer it to be set up on delivery for a price.
If not then what I did was to get a good TV man round to set it up for me.
I have a smart TV I am also a technophobe, the bloke not only set it up but showed me...
I also have a problem with my TV if anyone can help me as well.
I don't seem to be able to get Claire Balding off of my TV.
When I switched the TV off last night I could still see her face on the screen like the Turin Shroud.
