Unfortunately you wont find a wiring diagram. I have a Damon Daybreak similar to yours but a little different. I found the receptacles within 10 -12 aprox to the gfi in the bathroom were on one breaker. the rest were on another breaker. They all run in series, that is black, white, green in and black, white, green, out. Did you remove a receptacle when removing the entertainment center? With having a dead front, and a dead rear receptacle, you have taken something out of the circuit. If you hook up the wires ie black to black, white to white, and green to green, you should be back in business.
