alesis M1 active reference monitor problem ??

Hi I'm looking for alesis M1 active reference monitor diagram ??

I have just got one on the bench with a problem in that it doesn't pass audio & the on light pulsates when turned on.  Opening the speaker up there is a large electrolytic that looks bloated, that I'm going to change.

Doing a google search it seems that the PSU's are notorius in these.  Does anyone have any tips, since I am not very familiar with switchmode PSU's.

Yo Rob, did you find a Schematic?
Have one on the bench with the same problem.
C8 tests bad, and there's a resister (R27) that's so burnt i can't read what value its suppose to be.
cheers

Forget that, i can just look inside the other monitor when i visit the studio tomorrow...

An electrolytic capasitor in the switch-power has dryed out.
I think its 220 or 330uF. Change this and evrythings back to normal.
