Tablet repair technicians can be found online at major repair websites like UbreakIFix, IFixIt and Zagg Phone Repair. An Internet search for "tablet repair" for your local area will return companies in your vicinity that can perform tablet repairs.
Most companies and technicians who perform phone repairs also perform tablet repairs. It is important to check for reviews for any repair vendor or technician. Always check to see if your device is under warranty. Even if it is not, contact your manufacturer, as some manufacturers have policies that are more permissive than those stated in the terms of the warranty.
