New FIOS install-only one audio channel

[#1]

FIOS TV is great except that now I only have one audio channel (L) from my old(er) 5.1 Sony Home Theater.   FIOS was installed today replacing an a Direct TV setup which was at least able to play left, center and right (L,C,R).   I have no idea why I only have one speaker playing since the installer used the same plug ins that I had connected to my Direct TV.   Anyone have an idea why this is happening?

  What kind of cable(s) are you using for the connection to the home theater? Is the cable(s) coming from the Verizon cable box or from the TV?

   If you are using two RCA audio cables (red and white), then one may be defective or not fully plugged in. Left is white and right is red, so check the one going to the red connector. You could try swapping the red and white cables. If your setup now has only right channel, the problem is with the "red" cable.

   If you are using digital coax or fiber optic cable, then I would suspect the device connected to the home theater (either TV or STB/DVR).

Geez...thanks a lot for this simple (yet effective solution).. It worked!   The red RCA plug in was about 1/8 of an inch out on the FIOS DVR  from the connection and that's why I had only one audio channel.   I should have checked the connections initially but it did not occur to me but fortunately it occurred to you!  Thanks again.
