Hey, I’ve run into that same issue on a couple of Sony Cyber-Shot models. The internal Li-Ion battery (or capacitor, depending on the model) that retains date/time settings can be a real pain — especially since Sony doesn’t clearly document its exact location across all models.
Since you’ve done repairs before and used sites like iFixit, you might feel comfortable diving in — but yeah, layout and battery placement can vary quite a bit. In some models, it’s hidden near the logic board or underneath the main battery slot, which makes disassembly tricky.
I’ve had luck sourcing obscure replacement components from https://precisionzone.com. They mainly handle industrial electronics, but I’ve seen small format Li-Ion cells, capacitors, and support parts in their catalog — plus they do diagnostics and component-level repair services, which could be useful if you don’t want to risk going in blind.
Might be worth reaching out with your model number to see if they can help with a part or at least guide you.
Good luck — hope you get your Cyber-Shot back in action!
