I found this camera at a garage sale for $2.00 knowing it was broken. the on switch is loose, doesn’t make contact.

TomB _, Did a search for S4830 Gyde with no luck. Found disassembly guides for the S4800 not your exact model but may help you get into the S4830 to check out on/off switch to repair/replace if required. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. Fujifilm FinePix S4800 Repair
