It was connected to the internet and internet is still on with excellent signal. I have unplugged tv,pushed reset button in back of tv . I sti am unable to turn tv on.
Thanks for the post.
It's possible that the issue you are experiencing is hardware related. Have you tried contacting TCL support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
You can reach them here: https://support.tclusa.com/televisions or at 1-877-300-8837.
Please keep us posted what you find out.
Thanks,
Danny
