You or they could probably contact Boyue/Boeye and ask for warranty information and if it's possible, send you a spare screen and instructions on how to replace it (either by you or someone who's capable of repairing electronics in your area).
Or if there are technical support centers for Icarus, Energy Sistem, or any other company that sell products made by Boeye, they could email them and ask them to repair your device (Only Energy Sistem would have the E-Ink Carta panels though)!

I had sent emails a few times to the email address in the first link (sales@szboeye.com) and they answered within a few working days. There are Skype and the Chinese QQ services' IDs there, too but I don't know if they'd answer them! There are a few phone numbers both on that page and on the back of the device's box, also an email address which is "by@boyue.com"; I don't know if emails under the Boyue.com domain would answer non-Chinese emails, tho.
If non of the above worked, you could ask someone who can read and speak Chinese to translate the papers that came inside the device's packaging and find out if there's any info about tech support on them or not (or even call and ask them)!
