Hi, @LaurenHin and @ncservak.
Welcome and thank you for posting here in the Roku Community!
Thanks for bringing this to our attention that your Roku TV went black after the update.
Can you specify which Roku TV-manufactured brand this is? (e.g., ONN, TCL, Hisense) Also, have you tried plugging your Roku TV into a different power outlet?
Please keep us posted.
Regards,
Reynan
