Tras varios correos me manda esta solucion :
Thank you for your kind reply.
In this case, would you mind to fix it in local repair shop? If the price is reasonable, we can response the repair fee. You can go to check what is the problem of the tablet and ask for the repair price and if there’s diagnosis fee first. If you would like to accept, please inform us the repair fee before you fix it, or we will not respond the fee. Hope you can understand. Again we're sorry for the trouble.*
Looking forward to hearing you soon.
No pienso ni preguntar aqui , porque seguro me cuesta igual o mas que la tableta......
