Question about Televison & Video
Help!!! I have a new Direct TV HD DVR HR20-700 that will start to hum softly then gets louder after a few minutes...Here is the kicker if I change channels, and go back to this channel it clears up for a few minutes, then the problem comes back. seems to be channel dependant??? It will also clear up for a few minutes just by removing the hdmi cable and plugging it back in. other channels don't have the buzzing though.
The cabling is very basic... HDMI from the receiver to the Samsung LCD TV, and a optical cable to the receiver. the buzzing is on both the internal tv speakers and the receiver connected speakers.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

With the RGB you have to run seperate audio ,I think you have ran the seperate cables for the sound but they are in the wrong place.try changing the RW from the DVR to the TV and you should get sound from them.The unfortunate truth about the HDMI is that the HDMI format has a problem effectivly communicating between components.I am a Directv certified High Definition technition and %50 of the TV's that I connect the HDMI to will not receive the signal.One trick that I have found that works is to make sure you have a picture on the RGB then connect the HDMI.Once you have these connected ,turn your TV off and unplug the power cord from the DVR for 30 sec then plug the DVR in and wait 5 minutes for it to power up then turn your TV on and switch to your HDMI input.This method sometimes works to "Jumpstart" the HDMI input on the TV .There is no guarantee that this will work but is sounds like for now this is your only option,GOOD LUCK.

I would agree with mjjdesigns. You will likely need to get a cable card, which luckily the Tivo supports to receive the HD signal. Your Tivo may be able to receive the channels without the Card, though I have found that they are often mapped to funny places, for instance on my network, Channel 3 which reports as cable channel 403 with the CableCARD, shows up as 84-3 on the TV and Tivo if not tuing through the CableCARD.
It is possible that you think that you are getting an HD signal through the TV just becuase it is showing up in the 16:9 format. Unless you are tuning to an HD channel (such as 3-1 or 5-1) it is standard definition being stretched to fit your screen. Your Tivo can do this to by pressing the Aspect button on your remote, but it still won't be HD.
Also, if you do get a CableCARD from the cable company, be sure to ask for a multi stream card so that you only need one card and can tune to cable channels on both tuners. Also, I know that the cable companies have often had significant trouble getting CableCARDS to work with the Tivo. Be patient, it is often the Cable Co's fault but they typically pass the buck first to Tivo. Tivo has a hotline established for the sole purpose of working with the Cable Companies to make the cards work in their devices. If you wind up in the situation, call Tivo Customer Service and ask for this hotline.
Hope this helps - Flub

The problem could lie in youir HDMI cable, this is a common issue. if you swap HDMI cables and still have the same problem then bypass your A/v rec and connect your 622 direct to your tv and see if the problem persists, it it does, then your DVR needs to be replaced, you can call dish for addition troubleshooting if it is in fact your DVR.

You can do that but it still won't work. You have to make the changes with Direct TV in person for them to "authorize" your new receiver. More is needed than just the card.
