I have an HP pavilion windows 7 laptop and I have completely smashed the screen. It wasn't an issue as I could still use the laptop when I connected it to my Samsung TV by HDMI cable. But the other day I did something with my avast which I thought was an update. It told me not to turn off whilst it was doing this so I left it. Next day I turned laptop on as usual along with the TV. Did everything as usual as before but now it won't work and the TV won't get the laptop screen through the HDMI. Just says no signal. I don't know what to do as I can't see the laptop screen. I can't afford to fix screen and I have everything in this laptop.
