I used this quite a while ago, but I don't use it at all anymore, so I'm putting it up for sale this time. I tried replacing the battery to see if it still works, and the screen turned on, but there are lines and it's hard to see. So, is it broken? (>_<) I removed the old battery. I'd still like someone to have it if they want it (　´・ω・ ` ) Thank you for looking!
