I tried to connect two additional speakers for the exterior of the house using an A-B box. It didn't work.
I then put the system back together as it was before using the manual Operating Instructions. No sound.
I disconnected and reconnected everything again but still have no sound.
If you get a F61 error when the unit is powered on then the output ic is bad.Subwoofer has the power amp built into it.You may have damaged the IC with a mixup in the +/- speaker hookup and the common ground connection in the A/B box.Seems your subwoofer will need service.

The DVI mode may not carry audio information. The HDMI connection has audio information in the cable with the video. S-video and RGB do not have the audio.
If this is the case than a pair of Red/White audio wires that have RCA connectors on either end need to connect between the Direct TV box and TV. If HDMI is available you would not need to use the additional cables.
If you end up with the additional audio cables you may need to adjust the settings of the TV using the menu feature on the remote.
Many a times the speakers in flat panel TVs go bad. You either change the speakers or hook your tv to some sound system like a home theater or some music system in your house. There is AV out sockets at the back of the TV. Out of the three ie. yellow, red and white use red and white to connect to the music system, put the system on auxiliary mode and enjoy the sound of your tv. Good luck.

check your speaker wiring, make sure both terminals are connected properly. or could just be left speaker is disconnected. and is set in stereo mode which will only play left and right front and Sub, if you have one. try chaning the surround mode to play in multi channel speaker which will send sound to all speakers. i trust your using a Digital audio cable from your source ( cable box, DVD player) if your using analog audio cable you will only get stereo sound, and nothing will ever come out of the rear speaker unless you change the surround mode to multi- channel speaker. also in the setup menu you should be able to perform a speaker setup, make sure all your speakers are able to produce sound. follow speaker setup mode in menu, make sure you have checked the boxes or Yes to speaker you have in your system. then perform calibration and a test tone will come out of each speaker as you select them.
your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
