Old 3dsXL is stuck on black screen with back light when i boot up

[DomXYZ]

Luma and Godmode9 still work when i try to use them but otherwise just stuck on black screen eternally, it somehow fixed it's self before and started working after i let it stay on for a long while like a couple of days but i tried to launch Twilightmenu++ and that's where the screen went black and now I'm stuck with a black screen when i turn it on again, Luma and Gosmode9 still work like before, and the black screen still occurs even when i take the SD out, replace SD or take battery out, also Rosalina menu still works as well.

I'm having exactly the same problem with my Old 3DS (also same behavior with Luma Menu, Godmode9 and Rosalina).

No idea how to it got "kind of fixed", but I let my 3DS on (no SD card) for a few minutes and the Home menu just showed up again.
Turned the 3DS off, put the SD card in, powered it on, and my games were still there, thankfully.
I don't have Twilight Menu, but I'll install it and try it out.

Doesn't seem to be a hardware issue...
But I have not idea how to get this fixed. I wonder if formatting will help, but I'm a little bit scared of trying.

Does anyone have any advice?

[Update] Twilight Menu works fine.
