Lapbook 15.6” new motherboard

Hi, I’m new to the forum, but I would like to know if it’s possible for me to purchase a replacement motherboard for my Chuwi Lapbook 15.6”?
It no longer charges I.e. has no charge light and does not boot or show any sign of life. I have tried a replacement charger, with no success.
I believe my only option is to replace the motherboard as the Lapbook is now out of warranty.
Thanks.
