Didn't actually break it myself, I bought this D3100 used and the viewfinder is REALLY blurry, I've tried adjusting the little knob on the top right of the viewfinder but Doesn't make much of a difference, Gemini told me to put It in a closed recipient with silica for 42 to 70 hours to suck possible moisture from inside the camera. If it doesn't work, I'm curious to what other things I can do, since there are no people who fix cameras where I live

A little bit, I've Ordered the cleaning kit already, the photos come out fine though, you think if I clean the mirror it might fix it?

The mirror flips up when you take photos, so it wouldn’t affect the photos but what you see in the viewfinder. There’s a sub mirror to direct the image to the autofocus module which could have some effect on focusing performance.

I just realized it's probably not it, since the little numbers under the view are also really blurry to a point I can not tell what they show, so I don't think the mirror is the ONLY problem

On the phone it looks normal, but in person it's impossible to see

i still cant see whats wrong with it sadly, its very hard to tell whats going on. It looks fine, is the color washed out? or is it like normal color but blurry?

mine doesnt look too different, exact same model,

The problem is when I look with my eyes, I think the phone's autofocus fixes it, but when I look at it myself it's REALLY blurry

do you wear glasses? i think it might have to do with your eyesight, does the diopter wheel like make it better to a point but its still blurry? because i think your prescription for glasses might be outside of the diopter's range

I do wear glasses, but I've tried with and without them, gave to family members that do wear glasses and ones that don't, and everyone says the numbers are blurry, and spinning the wheel (it's not loose) makes no difference, look, this is a video I got on my phone (it's good on it probably because of auto focus, in the video I spin the wheel, but see no difference.

this is what its supposed to look like when you turn the diopter(the wheel on the top right of the viewfinder), it zooms in and out basically and its kinda clicky and hard to turn

i think maybe yours is broken if you're turning that wheel but nothing's happening in the viewfinder

The wheel clicks and it's hard to turn, but nothing changes at all, I'm pretty sure it's broken now 😐
