None of trouble shooting info helps when screen is blank! Remote connection bar below tv screen lights when power button is pressed, that’s all!
Hi @GrannieK
Thanks for posting here in the Community.
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.
For a list of Roku TV manufacturers contact information, visit our Community post here: Contacting Support for Your Roku TV
All the best,
