My remote for the samsung htc550 home theater system does not switch back to the set top after I have switched it to my tv. I no longer have a working remote for it and do not know how to switch it back. Hitting the source button does not do anything.

Please check if the following link helps:

DirecTV broadcasts in stereo, which uses the front 2 and the subwoofer. There should be a program option to switch to either 7 channel or 5 channel stereo. Select that.

Possibly. I believe the HTC550 only has one audio input so you'll have to work around this. Check and see if you Hitachi TV has a headphone jack. If it does, patch the PS3 audio through the TV. Connect the TV to the HTC550 through the headphone jack using a 3.5mm to RCA cable pictured in the link.

I'd get on eBay and see if that speaker beomes available cheap. Search "Samsung HTC550 speaker"

make sure everything is plugged in right and that its on the right mode or input

Are you using HDMI (newer / latest style) cable from your TV set?
HDMI cable will pass HD video and audio signal to your HTC550.

If you are using an older TV then you will need to provide your own RCA cable.
Yellow = video Red = right audio White = left audio
to the HTC550 unit.

Press the BD RECEIVER/TV Button until it glows a Yellow color. Then the remote is set to control your Blu-ray. When it is green it is set to try and control your TV

sameproblem here! did you find a solution?

1. Go to the DVD input.
2. Select menu
3. Settings
4. Audio
5. ASC
6. Turn OFF the Auto Sound Calibration
7. Exit the menu
8. Go to the DVD input and retry the pro logic II button and switch to MATRIX.

(Also you have to enable the "matrix" setting each time on all of the inputs you use.)

i know this is going to sound stupid but i couldn't get mine to work either after following every instruction to the T. I then rechecked my optical digital connections again and found that I neglected to remove one on the rubber protective endings. I took it off and plugged the end back into my TV and BINGO! THEATER SOUND from my tv!
