logic analyzer HP1663E

[Dandy]

I have logic analyzer HP 1663E. The analyzer has damaged power supply board. The instrument was stored in a clean room with temperature around 20°C and not used over past two years. After two years I discovered non-working P/S. The P/S board is Made in China. For this board doesn't exist documentation (I have asked at Agilent). My question is how to repair it.

I think if you don't have any documentation or drawing, it's best to use the re-engineering method and make a schematic.

this is very difficult as the p/s board is very large and full of components.
