[Premium-Rx] Seeking guidance on WJ demodulator.

[Scott Schappert]

Hello to the list !

 

I am attempting to resurrect a WJ FDM demodulator, WJ9518AE-9, and have
found that there is no Vcc on the control circuitry.  The instrument has
very high-density wiring in the aft end, and the voltage regulators, and
associated terminals are very difficult to reach, with very little
registration of LVDC and signal lines.  I know this is really a stretch, but
does anyone have any level of experience with this demod unit, or any docs?
I plan to perform exploratory disassembly in an effort to bring it back to
life as a side project.

 

I thought I might inquire to the list, prior to any potential mis-adventures
I may experience along the way.

 

As always, much gratitude in advance for any (offline) information available
!
