Both RT and LT are not being recognized. I am using the controller with a PC and just changed out a couple of the buttons. I am pretty well versed when it comes to soldering etc and everything appears to be in place, and all other buttons/bumpers are working correctly. The triggers were working correctly prior to changing the buttons. I do not know what I screwed up. Thanks for your help.
You must have bumped the conector for the triggers when you changed the buttons. Open er’ up and check em’. Click the picture of the remote next to the question to access the guides for it. Hope this helps!
