I have just purchased a lifestyle 650 system. I hooked up a blu ray player (Samsung UBD6500) to USB 3 and I can get sound but no video. I tried several configurations including using an optical for audio with no luck.

Can you see if there is an update available for your TV? Typically these are located on Samsung's site HERE. Can you try to change the CEC setting on the 650 console from "On" to "Alternate On"? Here are the steps to do this:
This is a global setting and will apply to all inputs.
I tried the steps with alternate on and Cec off neither one worked. The only connection that provides video and audio is my digital cable box. All other inputs give sound but no video. I have tried factory resets, taking everything off and reinstalling, we have spent time with day shift tech support and none of the solutions have been successful. All devices work directly connected to the tv. After all solutions failed we were sent a new console which did not solve the problem.
