My Nintendo screen wont turn on but there are sounds

So, i played my Nintendo last night, plugged it up right before i went to sleep. I woke up, going to go continue my progress on Pokemon Scarlet only to find out my screen wont turn on? I can tell when i turn it on, its a really dark blue, and i can hear sounds if i move the joysticks or tap the screen, etc. but i cant see anything. Ive tried the power button reset but all it does it turn a lighter blue for a second then turn back off. There is no battery thing in the corner, ive left it to charge for an hour but it just continues. Worst part is its done this before and i dont remember how i fixed it! If someone could answer this please do, it would be highly appreciated because ive already tried to contact Nintendo help line but they cant seem to find a solution without me having to pay them money to repair it.
