Trying to remember a 90s era show...

It was about teenagers who could warp from place to place. I thought for sure it was on Nickelodeon but I might be wrong about that. Whatever channel it was on, I think it was early 90s. Does anyone have any idea?

was it cartoon or actors?

It was live action. The only other thing I can remember is that when these kids would warp it sort of looked like how a CRT TV turns off when it's unplugged. Also, it made a weird sound. Wish I could say more.

how old were the teenagers, younger or older? How many? Boys? Girls? white? Black? Asian? Could they warp through time, space or just from place to place on earth?

They were older teens, like 16+. Boys and girls. I don't remember the races, but probably a mix with mostly white characters. And I think they only warped from place to place on earth. Like if one of them was going to get hit by a car, they would teleport out of the way in a flash. I want to say that's how one of the kids learned they had the power.
I don't think it had anything to do with time travel or outer space.

AHH Fuck yes!! I just found it! It was a 1992 Nickelodeon show called The Tomorrow People. Here's the wiki. And a youtube video of the first episode:
Funny how I didn't remember it being British.

I have it on DVD from a price mistake, I got it for 5 bucks from amazon. I have been meaning to watch it but never really got around to it. Never saw it as a kid. I think there is another show similar to your description from the stateside though but I can't recall its name.

lol this is awesome.
