Repair to a Discovery 2200 Metal Detector.
I assume it was dropped at some point and likely had poor solder contacts
from the factory.
Disassembled and reflowed solder on coil input circuitry as well as
capacitors and other suspect connections.
Things to look for when repairing:
1. Bad / dirty contacts
2. Cracked / gray / cold solder joints
3. Power devices like FET's which fail short
Do not be afraid of surface mount. Take your time and you can do it!
