I'm no expert, but it doesn't sound like you broke your DVR if all your video sources are showing up as black screens. It sounds like your TV isn't recognizing any of your video sources. (I'm assuming that you're able to use your TV remote to change the video input.)
Try connecting your Spectrum DVR using a different input on your TV, if possible. If you use an HDMI connection from your DVR to your TV, maybe try connecting it to the same input that you used for your Roku.
Of course, when all else fails, turn everything off and then turn everything back on. In particular, be sure to reboot your DVR.
Maybe someone more familiar with Roku has some better idea of what's going on. |
