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
I think that you cuold look for the service manual, check where is the ic that connects the DC to DC converter and rplace one whith the other, or at least see what is wrong checking voltages
