Could be bad solder joints, which just exposed themselves after you swapped the cap, or a busted switch. You're going to need a soldering iron…

Shiny joint is actually good. You do not want joints with "sandy" surface. That indicates low temperature or missing flux. Check visually (*) for a crack in the joint or the PCB wires around it. Reflow the joints with a soldering iron. If you find cracks in the PCB wires then bridge them over with solder.
Replace the switch if the above does not help. When replacing the switch then check PCB visually again also at the location which was hidden below the switch.

(*) Use a good magnifying glass at least or a microscope at best.

If you do not have any experience with soldering/desoldering then watch some educational videos first. There ought to be a lot of them on e.g. youtube.
