Hk avr 645 no osd on samsung 780i plasma

SOURCE: no HDMI video output from AVR-588 receiver to plasma TV ???

You can also use a digital coax cable (color orange) to go into coax 1 for DVD coax 2 for cable box. Just make sure to set the coax in input settings. The coax cables are a little cheaper than the optical cables and work just as well.

SOURCE: HK AVR 645 7.1-Receiver Turns off when sound starts to come through

Hello, I didn't end up fixing the Blu-ray issue, but the TV issue was caused by just inverting the positive and negative cable going into my speaker. Odd enough, instead of just not working, it just flipped the entire system off. I can definitely see that that could be the issue, another one I thought of is, at the time I didn't realize that DVI doesn't play audio, only video and I didn't have a optical cable connected. I decided to avoid the hassle, sell the TV and purchased one that has HDMI. Muuuuch better.

SOURCE: How to connect BLU-RAY DVD player to Pioneer Plasma TV via HDMI

The best possible solution to your problem is :
Connect your blu ray player directly to the HDMI input of you Plasma and watch HD video....
and connect the 5.1/7.1 sound thru the optical or the coaxial link directly to your AVR 3805.
You will not loose anything on the Blu-Ray.
The sound is best processsed by the AVR3805, while the video, which is the real upgrade (BluRay) in terms of resolution of picture would be processed by your plasma.

Connect and Enjoy

SOURCE: connection problem with HDMI cables on Denon AVR-589

Hi dmsgolfer22,

If your Time Warner Cable box is old enough that it has a DVI output it may have HDCP (copy protection issues) with the receiver. If you are having to use a DVI to HDMI adapter to connect to your receiver (output from Cable Box to input on Receiver) then it's very likely your cable box may have may not output the signal because it detects the HDMI repeater in the receiver.

The two best options to correct this are:
1. Connect the DVI to HDMI cable directly to the input on the TV, you lose the convenience of the video switching in the TV, but it will solve the problem. Then connect the digital audio output from your cable box to the receiver, although you've probably already done this.

2. Contact your cable provider and check into the possibility of them swapping out your cable box for a newer model that would have an HDMI output. This would be the best option since the HDMI output on the cable box would give you both the Digital Audio and Video through a single HDMI cable.

Let me know how it works out for your, or if you have any questions.
