Thanks Carl, I'll try again and explain better what happened. "I urgently need help from someone who is willing to help, I bought a Nexus mp from someone and apparently the electronics had already been touched, I used it a few times normally, and the last time after walking for 5 minutes in a field, I found a large target that made a big explosion in my ears, making a deafening sound and then just silence, my coil only responds to large ferrous targets at 5 centimeters, I opened my detector to see if there was anything apparent, but I only found one thing missing (marked with a circle in the photo), and I don't think it has anything to do with the problem, I need
the schematic to track if there is something with the circuit (normal sound response with the detector connected without a coil, but once connected, no response), I need the circuit schematic to look for the problem with the circuit or the coil (10 bits 7khz), I attached a photo of the circuit but it was not uploaded (thanks Carl for letting me know, I hope this time it will be possible).

In the photo there is a potentiometer missing but it was because I removed it to remove suspect components to be able to test it outside the circuit and I still haven't replaced it, thank you for understanding.
