Answer to "Identify the component please"Hey Sebastian, Non Labeled components can be tricky. But I can at least point you in the right direction. First of all, if you’re not familiar with circuit boards, the “L” used in the designation “L1903” indicates that it is an Inductor/Coil/Choke (whatever term you want to use). you may be able to depopulate it from the board and flip it over. There may be additional markings on the bottom. Even if someone is extremely familiar with the form factor of that specific inductor knowing it’s exact value may still prove difficult without the BOM (Bill of Materials). You may want to hit up a google search on how to measure the inductance and resitance of a specific inductor. This will require some additional equipment that i’m not sure you have. Another tip would be to determine the exact size. Sometimes physical size is a good filter on sites like Mouser or DigiKey Hopefully this helps in your search.
Answer to "Right bumper only works when pressed very firmly"Your Problem is almost Certainly A Broken Bumper assembly. The only thing that is unfortunate is that the 1708 only technically has 1 Bumper assembly for Both buttons, as they are connected together by a thin plastic piece. (it’s a pretty crappy design too, they rely on bending of the plastic for the button’s behavior.) I’ve gone through 2 assemblies already (just installed my 3rd) as I use RB heavily in a few games. The first time it happened when I opened the controller I didn’t notice that the button assembly was cracked on the cross connecting piece that’s hidden underneath the center retaining clip (the part with the Bluetooth button hole in it). At a glace it all looked good but the button still felt squishy and required a hard press to activate and didn’t seem to return/click like the left one. You say you already opened the controller? I’d carefully pop off the center piece. if you haven’t already And check the whole assembly for fatigue, or cracks. There are 2 small pegs holding in on that would...
