Hello, I have an Xbox 360 S Corona disc, when you try to start, you only hear a "click". I initially checked the power supply, (substitution for another console) checked the touch buttons and put another PCB to which they are connected. The console still behaves the same. Voltages 3.3V 5V and 1.2V on the L5A1 L5B1 and L5B2 coils when idle. Do you have any suggestions for items that I can check / replace? I am not afraid of soldering even BGA and I am open to suggestions.
