Hi, I tried to do a Factory Hard Reset on my Roku Tv Model# TcL 55R615-B ,I held down the Reset Button with a Pen for over 30 Secs. and now it won`t Power on, It was working fine before that. I get a Solid Standby Light and that's it. What could have happened, do you think it messed up the Firmware or something? Thank You, waiting on your reply.
Have you tried contacting the TV manufacturer to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
