Gaming PC Turns on but no display

[laneh64]

ok so I just today finished purchasing all the parts to my new gaming pc. Before today I just had a MB, CPU and cooler, PSU, case, and RAM. before today I would power it on and all the lights would turn on no prob and run and all the fans would run. today I got everything else and installed it. I hook it up to a tv from my GPU through a HDMI cable and powered it on and I get no signal on the tv. nothing pops up.
I HAVE NO IDEA WHAT TO DO!!!! everything powers up and the GPU fans run and all the lights work and all but the screen wont display anything. on the I/O ports don't want to work either.
my build:
CPU: AMD FX-6300
Cooler: Corsair hydro h80i
MB: ASUS M5A97 LE R2.0
Storage: WD 1TB HDD
RAM: Patriot (1880 or something like that) 8GB
Optical Drive: HP DVD writer or whatever ts called
GPU: ASUS Radeon R9 270X 2GB
Case: Corsair carbide series 300r
PSU: Antec 520w

First off, are you 100% sure it's plugged into the GPU? I can't tell you how many times I've actually plugged it into the mobo. Also, are you sure that TV works? Is it set to the right component? If you can, try it with a monitor and see how that works.

yes ive taken it out and completely unplugged it. then put it all back in. everything on it powers upsnf the gpu fans are running and the power leds are green. my monitor wont be here till Tuesday and ive tried it on two different tvs. I have nothing else to try it on

My gpu sometimes doesn't recognize the tv,wait till you have a monitor to try it with.With me usually unplugging and plugging the hdmi cable to the tv get's it working again.
You selected the right channel?
