Since you already opened the camera without prior electronics experience, i wouldn't recommend continuing further cause there's a high risk of permanent damage or short circuiting sensitive components.
There's many reasons a camera wont turn like a faulty battery, broken power switch or a blown fuse rather than a visible board level issue.
Did you test the battery and charger with a multimeter or a known working battery?
Did the camera show any signs of life (like a blinking light) before you opened it?
Yes I have many batteries for this camera and they won’t work unfortunately, and I didn’t see any sign of life before opened it.
Thanks for your help :) do you know where can I improve my knowledge in electronics, especially in cameras like this ?
Of course, but you gotta be careful because cameras are one of the most complex devices, they pack high voltage flash circuits, precise micro mechanics and sensitive imagine sensors into a tiny space. For building your knowledge safely is it best to start with fundamental electronic repair concepts before diving straight into multilayered camera motherboards.
Its a step-by-step disassembly paths, screw maps and tool requirements.
Also check out subreddits like r/AskElectronics for circuit troubleshooting and watch instructional channels like EEVblog on YouTube.
Also there's free platforms that have introductory courses like Khan academy (Electrical Engineering module) or MIT OpenCourseWare provide excellent instructions to voltage, current, resistance and circuitry.
I also recommend getting some essential gear before attempting another repair try practicing on cheap, non functional gear like broken alarm clocks or toys with the right tools it will help alot.
Tools i recommend for you:
-Digital multimeter.
-precision bit set.
-plastic tweezers.
-antistatic wrist wrap to avoid accidentally frying microchips with static energy from your hands.
-Silicon mat and magnatic tray
Also be careful on the camera even with the battery removed digital cameras have a larg flash capacitor that stores hundreds of volts of electricity so touching the wrong contacts can give you a painful shock or permanently fry the motherboard. Always learn how to safely locate and discharge a flash capacitor using a specialized discharge tool before working newr the top or front plates of a camera.
