How can I get my VCR to work after a power outage? - connecting emerson vcr to cable and dvd box

I have connected an Emerson VCR to my TV with a Comcast cable. For the last power failure, my recorder does not. When you click the light to shine, but no audio / video, and I can not even open the menu. I've tried pressing the TV / VCR input on my TV remote control, but without success.
