Amazon Kindle Basic (2014) Display Problems

[hanalee]

Hi.
There is a problem with the Kindle Basic screen.
The panel is not broken.
But it does not display normally.
It is displayed in black and a line as attached picture.
This is what the last line of the boot log shows.

'monitor: writing_file: file = / var / local / upstart / system.restarts: file = / var / local / upstart / system.restarts
info system_monitor: task = system, reboots = 9398 :: '

And reboot automatically.

I tried to connect the ink panel cable to another device, but the screen came out normally.
Is the motherboard chipset damaged?

Please help me.

You now own a used, spare, display.
The rest is junk.
