Have had this sys for about 2 years and recently moved it to another room but when re-installed it would only play through the headphones. Moved it back to its original position but it hasn't corrected the problem.
Hi I've just fixed this problem on my DAV S400. It's down to dry joints on the Amp PCB. Very simple to fix if you know how to works a screwdriver and soldering iron! Take the cover off and with the back of the unit facing you, you'll see teh amp PCB in the left hand corner to the back. At this time its the wrong way up to fix it so you'll have to remove the Ariel connection box and the speaker connection PCB both are very easy to do. Lay these out of harms way but do not disconnect any of their ribbon cables as its not needed. Now you can unscrew the amp PCB which is bellow both boards you have just removed. Disconnect the phono wire from the PCB (keep a note of that) and disconnect the power lead to the PCB on the right. Up turn the PCB and remove the copper heat sheild. You should now find the dry joints. The phono plug you just disconnected fits into a multi socket on the PCB. This will probably be loose or have more than one dry joint. Re-solder all these making sure not to link any together. Now find the large brown capacitor and check these joints and if needed re-solder. Check for any other dry joints while at this stage if any look slightly poor give them a quick dab with the soldering iron but make sure you don't fry a chip!!. Re-assembele remebering to reconnect the phono wire. I allways check before putting the case back on. This worked for my S400 after my 18 month old got hold of it. Good luck!
