    Pic of your board and the coupling capacitor (the 68nF one) can be highlighted, it is usually near SMPS transformer.

      Hi Tom66 just wondering if this will fix the dead power as there isnt even a 5v standby voltage. all the caps on the board basically had popped, thought changing them all would give me a little power back but no such luck.

          Probably wouldn't fix no power fault at all, the coupling cap is usually only used for main outputs. Check Vcc for standby IC, all fuses, output diodes for shorts & try listening for ticking sound.

            The capacitor is probably that little grey box wedged between the heatsink and topmost transformer.

              Have you sort out the problem ? What was exactly causing it ?
