Hardware O2DS not booting

[The0919]

I have an old 2ds running sysnand cfw on the latest luma, and it won't boot up. I was playing super smash bros 3ds and flipped the sleep switch, and when I flipped the switch, the screen lit up, but it was black. So I powered it off and back on, and I still got the black screen. I tried it with all combinations of cartridge and sd card in/out and rebooting it, but nothing worked. So I restored the nand and it worked fine... until the exact same thing happened again. In the same game under the same circumstances. I am wondering if anyone here knows what this is, or how to fix it.

One way to stop it from happening is too well not flip the switch when playing it lol. If you know it'll cause a break then just don't do it.

Also, when extended memory games are put into sleep mode suddenly at a time when they are calculating too many processes at once, you get a black screen when you wake the system up. You need to just wait, don't just press the power button. Sometimes it will even take 2-3 mins for me, but putting it in sleep mode again once can help get it unstuck.
