t.v. hdmi pc

[envirex]

I have an hp pavilion model No. p7-1459 and im trying to connect to a lcd t.v. via hdmi as i have no other cables nor a monitor to hook up with but when i plug it in it simply says no signal on the screen. I've replaced the graphics card with a radeon hd 6670 thinking it might be the issue but still nothing. It worked on the last t.v. and the only thing to change between then and now is that i moved into a new home. All the suggestions I've been getting from friends requires me to have a working monitor which i don't have.I've taken it in twice and all i got were either blank looks or being told it was the graphics card (which has been replaced). I don't really want to spend money on things that may or may not work. I've tried different hdmi cables and different t.v.'s which all work fine and still nothing. Any ideas?

You will need to get or borrow a monitor and then boot with the monitor and then install it ot the tv and configure it. Then it should work just fine.

Cant do crap if you cant see anything.

Bought a monitor and tried with both graphics cards, even hooked up with dvi hdmi and vga. Still nothing
