Sandy Chanton-Khemphomma as in where to take it, that is very hard to answer. I suggest that you check online for your area and see who does repairs and check their customer ratings etc. The ultimate goal of this website is to provide enough information to empower users to repair their own devices. So, in that spirit I recommend you use this guide Envizen V100M LCD Screen Replacement to fix it yourself. Here comes the real problem , since your tablet is slightly off-brand it may be difficult to find a replacement. Check the usual places like ebay.com alibaba.com or aliexpress.com etc
