Chosen Solution
Okay, I used the awesome tutorial and replaced the left joystick on the switch, it works great but now I can’t get the above listed things to work. I’ve taken it all apart and put it back twice and once the power button worked but not the volume. Any ideas?
My best guess is that you have maybe missed the yellow ribbon cable that runs between the daughterboard and the main board. Otherwise, there is damage to the connectors or cable itself. The fact that the whole of that side in not functioning is good (relatively speaking…). May I ask how you know the volume, and ZL and L buttons are working if power doesn’t? Good luck in any case
