No you can't, you need a new remote. You can only do basics without the remote.

That's because tha hdmi is desing to play sound to the reciver you may have to use out put sound from the unit.

You have to use the same connection in and out. You can not mix inputs and outputs (Example- HDMI IN will not play on Component out and Vice Versa.)

error 12 is when you autocalibrate and do not have the microphone connected, when that is the case the receiver can not detect the speakers.

The word UNLOCK may appear in the display if there is a problem receiving a digital audio signal. Follow the steps below to troubleshoot this issue.

1. Ensure the correct input is selected to receive the Audio/Video (A/V) from the appropriate source.
2. Ensure a digital cable is connected to appropriate DIGITAL jack.
3. Ensure the other end of the digital cable is properly connected to the A/V source.
4. Ensure the A/V source is set appropriately to output a digital signal.
NOTE: The A/V source may have a DTS setting that needs to be turned on, or a DPCM setting that needs to be set toDolby Digital .

I think you have to run a separate audio line from the dvd to the 510, because the HDMI is only passive

I called sony, even though the manuel shows that you can use a component wire to hook up the set top box and hdmi for the tv and dvd sony claims that you can not do this. The cable box must also be wired with an hdmi cable going into the video 2 port.sony claims it doesn't work using component and hdmi together because the receiver is unable to up convert. I hope this helps. I have not tried it yet (i'm at work) we'll see what happens when i get home.

please explain in better detail.

check the volume output from your components, and make sure they are not set too low
