A Video cassette is stuck in my TV-VCR Combo from emerson. How can I fix?

I was recording a cassette in the vCR and soon after it was done I started rewinding it and it got stuck. Now after this, the TV is not staying on, even if I turn it on, it turns off within few seconds and neither the Cassette is coming out. I tried to turn off the TV main power for hrs and tried to turn it on, still it is the same. Can somedoby help me with this?
