Please help in repairing and finding the schematic for this device

Looks like the manufacture date is 2007. It may be the EPROM has lost its memory, though the label over the window looks a good one. Someone has meddled with most of the trimmer potentiometers, that is never a good thing. The weak part of the hidden cable design is the cable gets a lot of mechanical stress. So try and test the coil and it's cable seperately. If you have a spare coil available, you should test that on the detector.

.Do you have a schematic for this device or swap

[Abo knin]

Do you have a diagram of the device or a picture of the board to monitor the changes that occurred to the board and the change of the variable resistors

No , I know nothing about this device, and was unaware of its existence until you posted this forum thread.
