I want to install a different color LED for the Xbox Series S "on" light. The LED can obviously be either on or off, as well as dimmed by a setting in the Xbox menu. Rather than just replace only the LED (LED1000) like others have done I want to make sure the resistor for the replacement LED is appropriate as well.
I got hold of the schematics and found that it has two NPN transistors, Q1000 which I get but it also has a second transistor (Q2000.) I can't really understand why the second one is there. Unfortunately I do not know the actual transistor make or model so I do not have the datasheet.
I have two questions:
- What is transistor Q2000 actually doing?
- What is resistor R2000 doing? Is it limiting current for both the LED and the Q2000 base pin?
