Faint lines on black TV screen after getting fibre upgrade

[Nawwti]

Moved to fibre last week, sky glass tv. TV now has vertical lines down the screen on black or blue backgrounds about 1 inch wide, watching programmes is fine but you can see it on the menus & screens with lots of plain colour.

Thought it was the TV but tonight I've noticed the upstairs TV is the same - downstairs is sky glass & upstairs is sky puck, so both run directly on the fibre, & it's a recent thing so likely after the fibre upgrade.

They aren't there on programmes, so I'm a bit stumped. Any ideas? Cheers

@Nawwti technically switching too fibre makes no difference to the digital data feed to the TVs.so I suspect the affect is co-incidental.  I would raise the issue with Sky but strongly doubt your new optical feed is the cause.
