No power to controller or av cable-ps2?

There seems to be no power going to the av cable or the controller. Machine turns on spins the disc but the light on the wireless controller does not come on. I have the av cable plugged in to a box that converts it to a coaxiel going into the tv. The box has a light on it that indicates when the box is in use, this light doesn't come on either. I have tried plugging in a slim ps2 and switching in on, both lights come on and the game boots up so I don't believe it is a gable issue.
