How do I talk to someone at customer service??

Amy_Sue, if someone is asking you for a payment for support, it isn't Roku!  If you have a Roku TV made by TCL, onn, Sharp, Hisense etc., contact their support.  If it's made by Roku, contact Roku support at https://support.roku.com/contactus.  To be honest, if I had a brand new TV that didn't turn on I'd take it back while I could.
