[Airu]

I'm a happy user of my kobo aura (1st gen) which I got second hand from for three month or so.

Yesterday I was transferring 20 or so epubs I downloaded online (7-22mb averaging around 12mb per file) into my kobo connected to the PC with USB while it was sleeping. Everything works. I was reading some of my other books (The newly sideloaded were displayed in the kobo, although I did not attempt to open them at any time after transfering) and I called it a night, I put it into sleep. And went to bed.

Next morning. As expected initially, it showed the sleeping, percentage read and book cover. However when I tried to wake it from sleep mode, it will never wake up. Its always stuck in sleeping. The screen looks fine without any lines or artifacts.

What I tried:
-Long press power button to ensure it off (over a minute) then switching it on. Sometimes..I can see the orange light from the power switch light up for a few seconds. I'm not sure if its the normal duration or not as I never really paid attention to said light.
-pinhole reset
-manual factory reset (There was again some light from the power button but it never blinked rapidly)
-Pressing the light button (No response)
-Connecting to the PC (PC can't detect it, even after trying to randomly press my kobo screen I hopes of getting it connected)
-Edit: Tried charging for 12 hours

All of the above, failed to trigger a change to the screen at all (pic attached). There was no trauma to it whatsoever at all.

What should I do senior ebook readers? There s no warranty anymore. Should I open it up? Is there a video how to (I searched but I didn't come up with any videos, please direct me if any? or if necessary at all?)

I really appreciate your time and effort into helping me. I just got my kobo. I did really hate to think it broke spontaneously.
