ht-c6930w powering on to D in input

I have the ht-c6930w and have the same problem (switches to D in on power on) makes no sense. its bee that way since I bought it 8 months ago! I've lived with this for long hoping for a firmware update fix. A company as powerful and respected like Samsung need to fix this problem immediately. I'm already too pissed off and would think twice before buying another Samsung device or for that matter recommending it to anyone. I have looked at many forums and no one with any solution.
Shame on Samung! have the guts to fix the problem you created!
