If you’re experiencing a black screen, you may be looking at a few different causes. A loose cable, the wrong input selection, or a lousy TV screen can all be culprits. In these cases, you’ll need to follow a few troubleshooting steps to get your Roku back to normal.
First, check your Roku TV’s firmware. If it’s not up to date, you may need to update your device to ensure optimal performance.

Another cause for a dark screen on your Roku TV may be connected hardware. You may be using a defective HDMI cable. If this doesn’t fix the problem, try a different HDMI cable. If neither of these solutions works, you can contact Roku support or try a help forum thread.
