Welcome to the Roku Community, @Ronique!
Thanks for letting us know about your Roku TV issue. We're pleased to help.
If your Roku TV won't turn on and only displays a blinking red light, even though it's relatively new, it usually indicates a power supply issue, potentially caused by a faulty power cord, a problem with the power outlet, or even a hardware malfunction within the TV itself.
Hope you'll find this info useful. Let us know in case you still have any questions.
Best regards,
John
