come on mate!

what was the problem?

It was no power (Sony Pcg 31311m )3v and 5v were not generating .then I
checked U65 in put and dc jack connector wow no voltage.I thought dc jack is
faulty. but its not, once i connect dc jack to the connector no voltage. once i
remove it voltage present at the end of connector. after that I checked dc jack
to ground component and those were fine.finally remove the board connector
and dc jack connectors soldered on board.wow works great!!!mysterious thing
is no problem with the removed connector.if you have come across with this
situation let us know
