[HELP] [RX100 IV] Flash suddenly stopped firing — possible contact pin issue?

Hey everyone, hoping someone has experienced this before.

My RX100 IV flash suddenly stopped working out of nowhere. It was working fine, then the next time I tried to use it, nothing — just the orange dot indicator staying solid (not blinking, so the capacitor seems to be charging fine).

Things I’ve already tried:
• Factory reset (Initialize) → no change
• Tested in full Auto and P mode in a dark room with Flash Mode set to “Flash On”

Here’s the weird part: the flash fires randomly when I gently press the flash unit inward. This made me suspect a contact/connection issue rather than a capacitor or flash tube problem.

I cleaned the flash contacts with a 70% isopropyl alcohol swab and noticed something — the left side of the flash unit has 2 contact pins, but the right side only has 1. Is this normal by design, or is one pin missing/broken?

Has anyone dealt with this before? Is this a known issue on the RX100 IV? Would love to know if this is fixable without going to a service center.
Thanks!
