Hello, this is my first /well second/ post, so pls excuse me if i am not doing it right 
i have Sony PSG-7153L, mb MBX-202. M791, shematic (i think)
the problem is - no power up. the jack is ok, there is power on the connector to the MB.. any clues what to check? (i have "some" exp. in electronics
(as far - there is no voltage on the power on button)
