Welcome to the HP Forums
I would like to take a moment and thank you for using this forum, it is a great place to find answers.
As I understand the HDMI connection isn't working on your TV,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
Have you ensured the latest video card drivers have been installed on your device?
Did you update the BIOS?[If not, Click here to find and install the video card, Chipset and Bios]
While you respond to that, here's what you need to do:
Most HDTV devices have more than one HDMI input port, therefore it is very important that the HDMI display's input source is set to the same HDMI port that is connected to your computer, for example HDMI 2 to HDMI 2.
If your computer and HDMI device use different cable types, you can purchase adapters. SeeOverview of HDMI and DVI Connections for PCsfor more information.

[By the end of this article all the issues should be resolved]
Keep me posted,
If the information I've provided was helpful,

that'll help us and others see that we've got the answers!
Good Luck.
