  1. C7G5 capacitor is missing, because I was taking photos at the time of its replacement, it looked suspicious
  2. Thanks for the answer. I took pictures of the supercapacitor area. The pictures of the whole PCB came out too blurry. I will try to take better ones The C7G5 capacitor is missing, because I was taking photos at the time of its replacement, it looked suspicious
  3. Hi everyone! I come to you with the following problem. I have an XBOX 1.1 in which no controller port works. The console is unmodified and has not been opened before. I took it apart to replace the clock capacitor. Before the replacement, the ports did not work either. There is a picture and sound. XBOX asks to set the time but it is impossible. I have two controllers. One original and one non-original. The non-original one I tested on a PC and it worked there, the other one I haven't tested yet. The other controllers I do not have. I checked the motherboard looking for broken paths, but I did not find such, however, I will check again. There is corrosion around the clock capacitor. Especially at the components R7G1, R7G2, R7G3 and Q7G1. It seems to me that the corrosion is only superficial, but I would prefer to replace these components. I found information that R7G2 has a value of 1.1 kOhm (SMD code 112) unfortunately I could not find anything about R7G1 and R7G3. Q7G1 is npn transistor - MMBT3904LT1. The question is whether these components are related to non-functioning controllers //edit I forgot to write, there is a voltage of 4.95V on the power pins, in the controller ports
