LG LFD790 installed with cable

I can get the LG LFD790 to work with DVD's, but not with my cable box and plazma. I have a comcast dvr cable receiver connected to my Samsung plazma via the hdmi cable. How do I get this so I can use the LG LFD790 home theater system with both dvd's and cable tv?

Re: LG LFD790 installed with cable

If there is an input on the back of your cable reciever get a fiber optics cable and put it in to your theater system and into the box then select "ez/optical" and your tv should come through, or you can connect the fiber optics cable on the back of your tv into the system and keep the tv volume off

I need the system cables and speaker cables for my lg lfd790 home theater system,can anyone tell me wer i can find them with out spending a fortune.

most of the cables can be purchased at "best buy" or other large electronc type store. If you can't find them there, try contacting LG and go to the suppport page and find the exact cables you need. I can't imagine these cables being so odd you can't buy the from a electronics or audio store.

I just need a replacement "system" cable that is similar to a ribbon type cable that connects the larger bass speaker to the dvd unit. This cable powers up the whole system.

The part you need is a LG EAD35001602. You can find them all over the internet. They aren't cheap however,

Here's one retailer.

Phillips HTS3566D Home Theater/Comcast DVR 3 Device remote

I have the same problem. The only time that I can get it to work is whenever I turn on the cable box the home theater system turns on too. When I use the DVR it will turn it on too and want to play the CD/DVD. I have a Comcast Motorola DCH3416 DVR box.
