Couldn't modify previous post, so here's another one, lol.

Tonight i spent some time on the machine to take a more systematic approach to diagnosis.
Began with testing voltages on rectifier board, both with J3 connected and not.

Results as follows:
TP.     J3 off.     J3 on
1        5.8vdc.   5.85vdc
2.       146vdc.  218vdc
3.       10.9vdc. 13.2vdc
4.       5.6vac    5.6vac
5.       44.3vdc. 44.0vdc

How do the above voltages compare?
TP3 which converts to the +5v regulated source seems fine, TP4 is low and outside of spec, TP2 seems low (backbox displays dont power up)

Does anyone have any direction or suggestion as to which components on the rectifier board are at fault?
What i'd really like is a components list, so i can replace everything.
Thanks
