Wi-Fi & connectivity

[Obamaslover]

It doesn't give me an error code or anything, it just says that there's no signal.

I've tried connecting with other cords, nothing

I've tried connecting to other ports, nothing

I've tried other things connecting (Like to my PlayStation), that worked.

I've turned it off and on, plugging and unplugging, updating drivers, turning off power saving, everything.

I’m not sure if I’m following exactly what you are doing and what the “it”s always refer to, but I think you are connecting a desktop or laptop HDMI output to a Roku TV. 

If so, you may need to make sure that the HDMI output on the computer is enabled and in used in the way you wish.  For example, on a laptop, the HDMI port might be turned off by default, and you might need to choose how to use it (eg: replace the main screen, mirror the main screen, be a second screen) and if the laptop screen doesn’t natively use a common TV resolution, you may need to do something about that.
