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?
