What is the make and model number of your TV?
The BOSE 321 GS can be connected to the Samsung LE32B530P7W using a Scart lead, and you should hear sound and see a picture when the correct input source (EXT) is selected on the TV.
If you can see a picture from the BOSE system but cannot hear any sound, then the Scart lead may be defective.
Try another Scart lead and let me know if that helps.
the scart lead was connected as you suggest and dvd function is working, the problem I have relates to no sound whilst on normal tv, previously on my old tv (sony vega) I could still get sound whilst on (video1) with just the scart lead connected. should I just get some phono leads to connect for tv sound through the bose?
have now connected phono leads directly,, problem is solved
