My Roku Hisense tv screen is black it still turns on but the screen won't show up can I get a replacement or a refund for it?
Roku doesn't manufacture "Roku TV" sets, it only supplies the Roku operating system. This sounds like a hardware issue that needs to be referred to the manufacturer of the set.

Check the wires
Tried power cycling the tv, but still, the black screen persists. So, start inspecting the wires because a loose wire can cause black screen issues. If you find any loose wire, insert it into the port properly, and if you haven't found any, then unplug all the wires connected to the tv and plug them in properly.
Also, verify that all the cables are working fine. If you find any faulty or damaged wire, replace it quickly and check whether the black screen persists
