My iMac won't power on only 1 LED lit

I have a Core i5 A1311 imac, I bought a refurbished board, I get one LED from the board, but it won't power on, and I know the power supply works, because my bad board gets power, just no video on screen. Is there a fuse for the power button port? and if so where is it?

Is this a good question?

How many green LEDs do you get with the bad board?

You'll need to return the board as you got a bad one.

Thank you, I'm getting a replacement board from the same company.
