M92 Defect

Hello there,

i have a M92 from onyx-boox.com since the beginning of last year and now occured a problem. All started with black stripes vertically over the screen, and the screen freezed. After several reboots the screen is all black and does not change. Connecting to the Pc still works, and the little light also reacts as i turn it on and off, but the screen remains dark, allso when it is turned off. Turning on sometimes shows the turning on bar at the bottom of the page, but then again all black. I tried to install the latest Firmware from Mobileread Forum, but i dont know whether it worked, as the device not showing anything.

Is there any solution to fix this problem by myself?
Does anybody has experience with the Artatech Team repairing Onyx Devices? Is it worth trying? How long does it take?

Unfortunately i need the Notes i did with it in PDF files, but they only appear as .sketch files, wich i can not open. I read in the forum that one have to merge the sketch and the PDF, what is now sadly impossible for me, as the reader does not show anything.

Is there a way to get the Notes (.sketch files) in the PDF file and print it, whithout a working M92?

Thank you for any reply!
