Ebook Hardware Documentation (Pocketbook Touch Lux 3)

[IV4ES]

Hi all,
I was wondering if there are any archives with the technical information regarding the PCB of the popular e-reader models.
I know for sure that there are always at least a few technical forums for almost any topic (like smartphones) for repair purposes.
I'm just having trouble finding them.
If anyone can point me to one of these or share the exact schematic I need, I would be grateful.


Background (if anyone is interested):
My Pocketbook Touch Lux 3 e-reader recently broke down due to water getting inside.
I have found that the circuit board is quite complicated and without a schematic it will be very difficult to troubleshoot the exact faulty part.
I can't deny that I will say goodbye to my e-reader and buy another one. But since it doesn't work anyway, I'd rather try to fix it before throwing it in the trash.

Probably not exactly what you are looking for, but this documentation seems to have some of the pin outs

Depending on the postage fee I could send you a functioning mainboard.

Interesting page.

So there's a lot more to updating the display than just pushing bytes to some buffer (re the Inkpad4/5 discussion):

Instead of pushing all the complexity of parsing waveform data and figuring out what to do to move the ink from a current position to a new one to kernel space, the driver provides the base interface for writing a precisely timed frame to the display. Waveform parsing, temperature adjustment of timings, and choosing an algorithm to update different regions of the display is left to the userspace, where it can be much more easily experimented with and used to provide the best experience based on what content is displayed in what regions of the screen.
