Dear forum users:
I am repairing a Marconi 2945A. Equipment was working up to the Self-test screen until trouble happened at Power Supply module 44991/179.
I am used to component-level troubleshooting and Power Supply repairs; however, I have no detailed schematic diagram, just what comes in the Manual: External connections and block diagram.
I have the equipment Service Manual but neither the diagram nor the components are listed.
Module is defective and I am looking for:
A. Schematic diagram.
B. A complete working replacement module. (Refurbished is acceptable)
C. A qualified service center where I could send the module for repair.
Any help is appreciated. Thanks and regards
