This failure is frequent in the dry welds Modiol must be re-welding the full Board Lalai special large IC-print, if you need to be sent to the service manual ok

Hi
You need to refloat the ic's in the dfs module.Not so easy with a 40w weller and not reliable.If you're in the uk,sers in sale(manchester) do them.If you haven't got a decent hot air device i wouldn't bother trying.
Good luck
Nick
