Sony ICF SW7600 neither AM nor FM reception

[Müller, Frank-Stefan (MRT]

My 22 yrs old Sony ICF SW7600 shows neither AM nor FM reception anymore,
I got the service Manual Ver 1.0 2001. 03, but I got no clue.

Any ideas?

Thanks

Frank

Is there other signs of life, display? audio amplifier hiss?

Dead IF stage? Dead audio output? (!!!)

You need to trace the signal through the radio. You can do this with a 'scope.
