OT: Toshiba Strata XXe Power Supply Help Needed

We use a Strata XXe phone system in our house, and after working just fine for many months, it suddenly went completely dead. No phones, no lights, no power light - nothing. We have checked the power supply, and none of the 4 breakers or 5 glass fuses seem to be blown. There was a diode near a bank of large capacitors which appeared to be shorted - it or something near it had gotten hot enough to blacken the PC board a bit. Replaced said diode with no change in status. AC is present on the primary and secondary of the line transformer, but that's about it. Primary bridge rectifier is fine. Anyone (Sellam, maybe?) have a schematic for the HPSU-9120 power supply (or a cheap source for a replacement)? We purchased a downloadable PDF of the installer's manual some time ago, but it doesn't have schematics. It indicates that you should try swapping out power supplies and/or checking the output voltages of the supply and replace it if they are incorrect. So much for that... Suggestions? -Bill Richman (bill_r(a)inetnebr.com) Web Page: http://incolor.inetnebr.com/bill_r Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.
