Problems with Display Screen - touch screen still works

I purchased my Fitbit Blaze second hand so I'm afraid it's out of warranty.

However, I'm wondering if I could get some opinions on what might be wrong with my Fitbit?

It was working perfectly fine for (about) a year since I purchased it, when suddenly today, I look down at my screen and see it having difficulty displaying. The screen appears fuzzy like there's something underneath the sensor etc The touch screen seems to work fine, I just can't see the display very well.

I don't wear my fitbit in water, the only way it might have gotten water damage is when washing my hands, but I'm always super careful.

I'm wondering if a replacement screen might fix the issue? I can't afford to buy a new one as I'm hoping to get the Versa and then I can give my husband the Blaze.

I appreciate any advice! Thanks!
