you need to find out what connection type is open on the receiver. Then start a search (google it) for a converter/cable to make that connection, possible site/vendor cablestogo.com. You want "HDMI to what you can use on the back of the receiver". You may find there is no such direct converter/cable at this time, meaning you may need to buy lots of converters/cables. I?m not an expert and the reason I?m posting is more info will be needed by someone who is. TV model and make, same for receiver with open connection jacks/kind and type noted, and everything else that may effect what you want to connect (number and type of speakers).
If you find a converter, watch out, it may turn your high priced digital sound into analog which may not run the surround sound correctly.
You may even find that the converter may need to be a Media PC.
If you find that the only input into the receiver is analog than maybe the new TV has analog sound out that you can use instead of buying a pricy converter.
If you do go the analog sound route, there needs to be a channel for each speaker. If it's 5 speakers than it is five channels, r front, l front, r rear, l rear, and sub-woofer. The more speakers the more analog channels.

Helping my parents set up. They've got an HDTV and a surround sound system. The receiver for the surround sound has a built in DVD player. Currently there's an HDMI cable going from the cable box to the TV. That input channel is HDMI 1. Surround sound works with DVDs, so I know that's at least working. What do I need to hook up to the receiver/cable box/TV to get surround sound on that input channel? The receiver doesn't have an HDMI slot. Thanks.
