New build on an lcd tv thats not giving a signal.

Hey, Im new to the forum. New help with a question. (gigabyte's tech support is taking a bit long.)

I built a new compy and hooked it to my lcdtv, (42" 1080p) using first using hdmi and then using a flat screen cord with a vga adapter, both gave no signal. everything is getting power, but just no video is getting pushed. the things that concerns me is there is no beep from the bios when i turn it on. everthing is getting power and drives are spinning.

this is the build that i have.
GPU: GIGABYTE GV-R587UD-1GD Radeon HD 5870
CPU: Intel i5 2500k
Mem: Kingston HyperX 8GB 2x4
Power:Rosewill RV2-700 700W

I thank anyone that can offer some help in this.

    Welcome to the forums.

    Are there two 75W 6-pin PCI Express power connectors connected from the power supply unit to the graphics card?
  2. Ya. There are.
  3. Does it work properly with a monitor instead of the TV?

    Do you have another PC that you can try the graphics card in? If it works in another PC then you can eliminate the graphics card as the problem and start looking for another component that may be the culprit.
  4. I hooked it up to a VGA monitor and still nothing. Now I'm pretty sure the motherboard is faulty. I'll try putting my video card in another machine though just in case.
