I am having the same problem. I'm trying to replace my Roku SE with the Roku Express. The SE works fine with my Vizio TV. I've tried all 3 HDMI ports, used the HDMI cable from the SE and it still doesn't work. The Express will work when hooked up to my Samsung TV. I'm at a loss

@deacsrider, one thing you didn't mention is if you're using the supplied power adapter and not the TV's USB port. Does the light on the front of the Express come on when you connect the USB power cable?

I am not a Roku employee.

I had the same problem with my older Vizio TV, no signal. After trying several different things, unplugging the Roku from the power outlet, then unplugging it from the TV. I realized that on these TVs you have to press the Roku stick firmly into the HDMI port until you hear a click when it snaps in the port. After that it has worked fine.
