So you have the TV set as your monitor and no other display unit.

Did you install an OS ? Or you connected everything and switched on the PC, waiting for BIOS post screen ?

Have you connected the external power supply cable to your gfx card ?

Have you seated memory modules properly ?

Do the fans for CPU, gfx card, case, etc. spin ?

EDIT: Did you switch to the correct HDMI input on the TV set ?
