Matrix 12 not booting up

2011-02-15 by r_j_d_2.phila

Hi all, im hoping someone might have some ideas/leads for me. upon turning on, my M12 is not producing sound, most red LED's are solid on, and the displays are blank. if i hold the "clear" button while turning on, the "RESET" option flashes for just a split second, then disappears.

i have checked the PSU voltages, and everything is within the specs of the service manual EXCEPT:

9vac reads about 6.5vac
55vdc reads about 60.2vdc

any ideas? are those within normal specs you think, or do i need to be concerned with that discrepancy? thanks for the help!!!
