When you say "...the usb is connected to power..." I'm not sure exactly what is connected to what. Are you talking about the full-size USB port on the S3? If so, I don't think power can be transmitted to the S3 from that port.
With a previous phone I had, I used an MHL Adapter. It plugged into the MicroUSB port on the phone, and the adapter itself had another MicroUSB adapter, to which I would plug in the phone's normal power adapter. It worked that way.
If you're saying your MHL Adapter has that accessory MicroUSB port, and that the S3's OEM Charger/Cable is plugged into that MicroUSB port, and it's still not working, then the problem may arise elsewhere. Or it's possible that the S3 simply doesn't support that type of connection.
ETA: the output from the MicroUSB port is going to be digital, AFAIK. So am MHL/HDMI Adapter would work fine. But if it's taking that digital signal, and connecting it to the analog-based RCA cable, I don't see how that would work. Somewhere there would need to be a digital to analog conversion, which your Adapter likely doesn't have.
