I think maybe one or more of the flatcables inside are no more connected.
moshe israeli:

moshe israeli:
can I check this with a multitester??
overover:
Hi moshe israeli,
here you can download the S550 Service Manual:
https://psrtutorial.com/lessons/workshops/ServiceManuals.html
Maybe only an internal multi-pin connector has "slipped apart".
I would check first the cables/connectors from/to the boards "PNL", "PNC" and "PNR" (pages 68/69 in Service Manual).
Best regards,
Chris
