I have an Acer Window Laptop that won't display on a Moniter/Tv

[Little Gecko]

I accidentally sat on my laptop causing it to crack with the screen having colored lines on it with a white background. I plugged it into my Tv with a Hdmi2 cord and it worked! However while I was playing a game on my computer my game froze. After a few minutes the screen went black and it said: No Signal!, HDMI/DVI. I don't understand why this happened. Please Help!
