So here is my problem, I recently order the parts and put together a new custom computer. However, having installed all the pieces and running all the wires for some reason it simply does not output a signal to my 37" LG HDTV via HDMI onboard. A couple points I would like to point out firsthand, I have been working on computers for years so I have lots of experience, however no real book knowledge. (bear with me please!!!)
Here are the parts I used and ordered via newegg:

Here's what I've done so far:
Okay, sorry for being so in depth on everything, but the vast majority of forum posts I've read in the past its almost always the same format -- (short problem) (asks for more details) (gives more) (asks for even more details) (gives enough) (answer) so i figured id skip the trash and get right to it.
1) Opened the case etc and bolted the three golden pins that go underneath the MOBO.
2) Acrewed in the MOBO assuring the "washers" were nice in between the screws and the mobo
3) Mounted my two hard drives in the front of the case
4) The processor heat sink already had thermal paste so there was no necessity for that, then I simply placed in the processor assuring the triangle was in the upper left corner as marked and then attached the heat sink and plugged in the cpu fan
5) Screwed in the PSU
6) Then I hooked up my two XFX 4870's into each respective PCI-E x16 ports (removing both of the metal things for each as they require two screws (huge bastards haha)
7) Installed all 8 gig of the mushkin ram and properly snapped them down
8) Since the case has outer features in the front (firewire, 2 usb, sound card etc) I had to plug those in however I didnt see one for the sound card so it remained unplugged and stashed somewhere in the top
9) Then I plugged in ONE 6+2 pin (only using the 6 pin) to each 4870, and using the modular functions of the PSU I ran two of those 6 pin to those little 4 prong things you use for fans or IDE HDD power, anyway it was 2 of those per 6 pin and I used one of each of those for each 4870 (trying to split up the "lower quality power" between them)
10) Plugged in the SATA power cables to the HDD and the actual SATA cable to the MOBO
11) Hooked up all the fans (240 and like.. 3 120's I think)
12) Plugged the two crossfire ties into the two 4870's
13) Lastly I hooked up a LG 37" 720p Television via HDMI to my on-board HDMI output
14) Turned it on and everything lit up, no fans were immobile, all LED's turned on properly, both fans on the GPU's were running, only one with variable speed (probably since I haven't installed any Crossfire drivers) and everything seemed to be great HOWEVER THEN my wonderful TV says "detecting input device" "no signal found"
I think that covers everything.
Here's what I am doing for the first time with this rig:
Pretty much everything is familiar territory (ive used this CPU/MOBO/HDD before with a single Card before) except the crossfire I have never crossfire'd or SLI'd in the past. College tends to keep you pretty broke.
Anyway, I wanted to say thanks in advance for ANY and all help I receive regardless of how it turns out.
