5.1 Surround sound not working

Do you have them connected to the sub? Those satellite speakers pick up the fainter sounds and work best in movies with 5.1 surround sound. Make sure they are behind the primary listening position. And try them with a 5.1 surround movie. If all speakers are up front switch to front listen mode. Good luck.

Reinstall the software for the sound system, this should redetect the speakers properly as 5.1 surround sound speakers.

If you do this and it still doesn't work then the speakers are bad and your sound system would need to be replaced.

I had the same issue, but apparently...it's not an issue. What I discovered is that the system was fine, but the station I was watching didn't broadcast in 5.1 surround sound. Therefore, only the front speakers will have sound. Try putting a dvd in, or listening to a gameing system through it. If you don't have sound after listening to something that puts out full surround sound, then you know you have an issue.

Yes. Make sure your speakers are first properly connected, then enabled to operate on the setup menu. Then run either a test tone for all channels or media recorded in surround sound or run in 4 channel stereo to test.
Not all media will produce surround effects 100% of the time.

Press the surround button on the Philips remote to see if the subwoofer will begin producing noise - the surround button switches the mode from simple stereo to full surround. I would test the surround button while watching a DVD, because not every tv channel is going to even produce surround effects. Good luck!

to localised your problem, try to plug your speakers to other sound source like mp3 player ,stereo system. if still no sound coming from it,your problem is within the speaker system. perhaps the audio power amplifier ic inside, need to be replaced.

This may be old news but just in case ...

Typically you need to consider the surround system as the central point for sound distribution (and in newer receivers, the distribution point for video signal as well). So you need to think of your TV and Satellite as sound sources and connect them to the IN side of your surround sound system. From the back of your TV then, look for the Audio OUT (commonly Red for right and White (or black) for Left. Connect these to the IN on the back of the surround system. Likewise for your satellite box. Then make sure you select the appropriate source on the surround system. If the system supports the video signal, you can route that as well. Beware that you'll need some sort of simulation (provided by the Phillips unit) to upconvert stereo to surround ... check the manual online. If you post model numbers for the Phillips and satellite units, we might be able to direct you more specifically (provided we can find manuals online)

i think it would probably be somthing inside the channel???

In case you connect the System to a TV set using the Scart Connector, only the video signal is terminated, Audio is actually not wired inside the SB100 Scart connector.
Sound will only be amplified through the system itself (through the satelites and Sub) it can not be utilized as a stand-alone DVD player.
So after connecting your surround speakers the problem will be solved

Press the SURR button until you get sound on all five speakers. If you don't get sound on all 5, there are a few possibilities:
1) the program you are watching only gets stereo sound or lower (only two or one speaker will play in this case)
2) you need to get a digital audio cable instead of using the red/white AV cable
3) a setting on the TV, cable, or satellite box needs to be changed to allow surround sound in full
