HP8594E Spectrum Analyser PSU attempted repair, nightmare PSU fault.

Hre we look at a faulty PSU within a HP8594E Spectrum Analyser, this particular power supply module has no service info available, just remarked upon by HP as module swap, so no circuit diagram, no block diagram, & no PCB layout whatsoever, so we are back to reverse engineering it & trying to understand how it works, We find during the process of replacing suspect components & fault finding & using another spare PSU for reference the failure seems to be on the Control board, & as such i discuss the different IC's on the PCB & find out what they do, there is a decision in the end to blanket change many components on the control PCB resulting from past experience & the fact the parts are quite cheap, from there its fingers crossed & hope it works, an update video will be completed once the parts arrive & are fitted,
