Okay, I called Samsung, they had me reset the main unit and wireless unit by unplugging the power and removing the TX card. 5 minutes later they had me plug the receiver and wireless unit back in. Plug in the TX card turn on the main unit and then the wireless unit. Still no dice. They had me reset the ID on the main unit with the 0,1,3,5, process, and then had me do the reset button on the wireless unit. Still no dice. They had me repeat this process twice. Still no dice. I'll be sending the unit in for repair. Normally I'd just take it back to the store and get a replacement, but I got this on "OPEN BOX" for $199.00 so I'm keeping it and sending it in for repair.
So far, Samsung tech support was pretty painless. Did not have to wait on hold very long at all, tech agents were well spoken and knowledgeable, and they were polite for the most part.
I'll report back on how the repair process goes.
