Yep, as I mentioned that is all out of the machine and I pulled said tants on the backplane - no love. Which were your bd ones?
I kinda been down these roads... looking for next road :)
- to recap (pun intended)
- - 15 bad
-- to quickly check if a particular board (vert, horiz, cal, Z) I pulled jumpers to each one by one. no love
- pulled main interface board which as Jon said has tants all over the place for -15V - I measured as many as I could find - no love at all.
I'm tryign to finish the isolation of SMPS itself VERSUS a shorted element in the mainframe. I guess Ill try to load down the PSU and see if standing by itslef its OK or not.
TY for the advice - it seems like I am following the manuals correctly as well as having read the internet accuratelty for what to do.
Oran- the manuals say to use a variac to decrease input AC voltage to troubleshoot the SMPS.
Thanks for the help!
