New Desktop PC to TV via HMDI= NO SIGNAL! Help :(

[GreyPhantom]

Hello, i newly assembled my pc and installed the mobo and GPU drivers (and OS of course), at the store using a display monitor (connected with VGA port)
Anyway, when i came home to plug it into the TV there was no signal on the TV!
HDMI works fine when connected to laptop, and the TV is relatively new.
What could it be?

Thank you...

Hi,
You should try to connect with a normal VGA or DVI cable, maybe it's stuck on loading screen or asking for unplugged keyboard, or some bios error.
Or maybe, the computer just set an higher refresh rate which TV can't handle.... use the VGA cable and discover

But... there's no VGA port in my tv OR my PC

On PC side:
Is your keyboard correctly plugged?
Do you have an internal speaker? when you boot it just bip 1 time or does some funny noises?
Do you have more than 1 graphic card? have you tried to unplug your PCIe graphic card and connect the TV directly on the motherboard (if it has an on-board graphic card)

On TV side:
Is your TV input source correctly selected?

Anyway you told on your first post you configured the pc with a VGA port, and now you don't have it anymore on your pc?

No i don't have it on my PC because i used an HDMI to VGA converter and plugged it into the store's monitor to install the drivers and OS.

Answer to your questions is:

Yes, the keyboard is lit up.
No internal speakers, it doesn't beep at all.
Just one graphics card, and nope

Yes.
