Sony ICF-SW7600 no AM and FM reception
If I remember correctly, the front end FET (Field Effect Transistor)
in the tuner section sometimes fails in this model series. This is not something you can fix yourself unless you are experienced with this type of service work, and can work in RF circuits. I cannot remember if in this model this transistor is an SMD type. This FET failure is more common than other types that inhibit this radio from working properly. There are also other types of components that can cause failures. I would not be able to suggest anything else without troubleshooting the set using the proper diagnostics processes.
