I bought a Hisense Roku about 3 years ago and it’s been a great tv, but about 3 weeks ago, I turned it off to go to work, and when I got home, the screen wouldn’t turn on. The red power button will cut on, then it will blink 2 or 3 times, and then it will do it again, in a cycle. I changed the power chord thinking that would be it but It didn’t stop. The screen will not turn on at all, and it’s incredibly frustrating. Is it a power issue? Do I need to get a new tv or is there something I can replace to make it work again?
A number of TV manufacturers license Roku technology for inclusion in some set models and market them as "Roku TVs". Roku doesn't manufacture "Roku TV" sets, it only supplies the Roku operating system.
This sounds to me like a hardware issue that needs to be referred to the manufacturer of the set.
