Like I said, map and draw out the over heating 350's circuit. If its being supplied by the +5.2v supply is providing a voltage reference in the 3v range. If that's 0vdc at pin 2, fix that then proceed on to isolate what hangs on the voltage bus. This ain't rocket science guys just methodical troubleshooting without a schematic.
See my thread from 2013 - I had probably a similar problem with
my 54542a which has the identical power supply:
In my case it was the -12V generation which was faulty and I already
drew the schematic in 2013...
And yes - this is no rocket science, but it is very cumbersome
to do measurements on the opened supply as the cable to the
oscilloscope is rather short ;-)
Good luck to Michael and his 54542C...
