New tv - Sky News signal break up when on RGB setting

Am on Freesat from Sky with an old Panasonic box and a new Samsung TV connected via scart. Everything was great on set up - apart from pixelation and break up on Sky news. Which was odd as the one channel I could get even in bad weather was Sky!
However when tinkering with the Sky remote settings, I discovered that by switching the picture format from RGB (which I used with the old CRT) to PAL the problem was sorted.
Ive always preferred and used RGB. Does this mean the new TV is formatted just to work with PAL?

That's a standard fault on that specific Panasonic TU-DSB model.
Not worth repairing.

Thanks. I've had a slightly iffy reception on a couple of channels for a while but Sky News was always OK. Maybe the ancient Sky Box worked better with the equally ancient CRT!
