Why won't my tablet turn on past the splash screen before android?

Hi, I have a ‘Telekids’ branded Kurio 7. When I try to turn it on I get the Telekids logo but nothing happens from there. On this screen there are 2 noise-looking lines at the top, sometimes 3. They also differ in width whenever I turn on the device. I don’t see the animation that happens after this splash screen. It can’t be the battery since it also happens when it’s unplugged. I tried both having it on the wall adapter and on a USB charger.

I’ve tried entering recovery mode, but to no success.

Does anyone know what this is and how to fix it?
