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

It can be something easy like a loose cable.. But if it fell on the floor then be prepared to take all the boards out and look for cracks...

Hi moshe israeli,
unfortunately, I can not give you more detailed information, at the moment.
I will come back here later if I find out something.
A Happy New Year to you, too!
Best regards,
Chris
