Hello Yasmin23, welcome to the HP Forums.
It appears that you've done something and can no longer see video on your tv from the notebook, but can hear the audio. I will try to assist you with this.
I recommend starting with these:
Connecting a TV or Monitor to your Windows 7 PC using HDMI
HP Notebook PCs - Resolving HDMI Display and Sound Issues
Let me know if they were able to help you.
Thank you for posting on the HP Forums.
