Hello! I would like to ask you the following. I have the same problem as the video, after checking and see that I have the same results as you, remove the transistor and instead of 15v I have 10v, I still do not put a new transistor so I do not know the result. I would like to know some recommendations. Thanks and very good work!

You can replace a new N-channel mosfet or you can short with jumper wire.thanks.

@@Laptop_repair_zone I have turned to you again. After changing the UZ1 and effectively, it gives me current in the indicated terminals, which did not happen before. However, instead of giving me +15 volts like at 5:25, it gives me 9-10 Volts, and the error persists. In the + VCC_CORE (6:05) does not give me any voltage, it stays at 0. Do you think you could give me some indication of what else to check or review ?. Greetings and good work.
