On power on displays "Défaut", according to service manual, issue with communicating to analogic board.

The PJN 5208 analog board match ours, except for more-or-less two ICs missing in the 5208.

Analog board has some issues:

  • missing components
  • unsoldered one, never soldered back
  • DC/DC cooked

Ordered:

  • LM308AN (IC CI8, missing)
  • DG419 (IC CI6, missing)
  • MC1403 (REF1, missing)
  • 7660 (IC CI3), DC/DC with a very little crack on top, and hot on power on
  • 1N4448 (D5, missing)

There might bee the need to replace two inductors, but no big deal for now.

The 7660 has ~8V on input, should take 5 according to schematic. trace back where it comes from after unsoldering it.
