Pot O Gold 580 power up problems. Help needed

[Venang]

I am having trouble with my pot o gold 580 machine when powering up. When I turn it on, the box which says "No Signal" comes on for a quick second and goes straight to the power up test screen. It then loads to the game selection screen. If I was to either put money in the bill acceptor or touch the screen anywhere it would automatically black out the screen and goes back to the power up test screen again and again. I'm not sure if there's a loose connection or if the bill acceptor is the problem since it always happens when I insert a bill. Also after inserting a bill, the bill sometimes does not go into the money box and just lays on the outside of the box where its supposed to push in. If anyone has ever come across this issue and have resolved it, I would appreciate your expertise on it very much.
