3ds XL bottom screen replacement

I am going off to college this year and want to bring my 3ds along with me for the long commute but the bottom screen is completely black. It started warping and bleeding colors on the screen and i found that pushing around the edges seemed to fix it temporarily but then eventually the screen went black and no matter what i did it wouldn’t turn back on (top screen is fine) touchscreen does appear to function although i have no idea if it’s accurate. I looked around at places near me to get it fixed and brought it into estarland who turned me away saying to wait a month and they will email me when they aren’t backed up. it’s been almost 3 months and still no answer. So i’m considering fixing it myself but am afraid to do so as last time I opened a device I completely broke a ribbon cable and had to throw away a joycon. I’ve heard it’s easy to fix but i’m scared that i will permanently break it should i attempt to fix it or should i keep waiting?
