my Roku is getting power but when it's hooked up my tv, my tv reads no signal. I have tried the other HDMI input slot and same thing. I have hooked other devices up in the same slots and they work just fine. HELP
When you say it's getting power, are you using your TV's USB port or the supplied power adapter?
I've used both, it's currently plugged into the power adapter
Navigate to your TV settings (TV Menu Settings) and look for something that allows you to Enable your HDMI CEC.
Also, do you see a little blue light or something on your Express when it is plugged in?
Post back your TV model if having trouble with the CEC.
