Main board swap - how to avoid problems?
I’ve got Sony with a power problem. After investigation I found it has an essential chip (IC5700) killed by a dummy battery. It can’t be replaced, so I have to do a whole main board swap.
It’s (insanely) pricey, but possible. The problem is - many report that after a replacement camera may malfunction: EVF may stop working, AF problems, some functions get disabled. As it’s costly thing to do I’m very nervous - how to guarantee myself from such things?
Service manual describes how to transfer needed data from an old board, but:
Old board must work (which it doesn’t want to do);
You need Sony Adjust Station software (which isn’t available).
And I have some suspicious thoughts on that…
What should I do to get this cam working again? What’s your experience?
UPD. Board photos if needed
Can’t say if it’s useful though
