main large board had a blow on it changed with a new board but it had yellow tape across the top plug in connector where the feed from the on/off switch fits.thought this a bit odd as if not to fit this connector but nothing on leaflet re this.anyway switched on and dead no power to board switched off and fit the grey connector switched on and bang!.checked all my other connections and all are in correct place anybody had this before i have since turned on again for a split second and there is a little firework display on the board.
any body got any info on this machine.
cheers chris
