Orange and Green screen

[MiniHero]

I purchased a fitbit less than a month and at some point on my run this morning it froze on a black screen. I reset it and everything seemed fine. It synced to the phone. A few hours later, I woke up from a nap and the screen was black with a line on the left hand side, which was half green and half orange. I've tried to reset it but it's had no impact and now half an hour later the line has moved across the rest of the screen, leaving me with a half orange and half green screen. Any help would be appreciated? Thank you.

@MiniHero what Fitbit do you have?

The Blaze hasn't been sold for about 3 years.

Have you tried a restart?

I have the FItbit Blaze. Yes I tried that it didn't work. I've sent it back to the company that I bought it from.
