Question about Sony ICF-SW7600 AM/FM/SW Radio
My radio is the 1991 edition.
FM ceased to work. Only part of the band at first - then nothing except the interstation hiss over total Freq range. Some motorboating in the early atages of failure then nothing.
No problems with AM, SSB & SW
Sony radios of this era had notorious capacitor problems.... also
several other brands were affected. These capacitors were underrated
and the technology to make them was not at it's best back then. The
cure is to replace the capacitors on the board with new electrolytics.
About 28 of them need to be replaced but the big problem is to find
someone to do this. the original capacitors are surface mount and must
be removed and new radial lead caps put in their place, some are rather
tough to get at and the new ones have to be placed carefully. My SONY
ICF-SW7600 now works as new and maybe even better!
I have done this myself as I have skills working with surface mount capacitors. I offer my services to those who cannot find service for their radios. Please email me for details, I am not into making bucks on this, I just want to see these radios kept working and bringing enjoyment to their owners.

Do you want to repair it at own? if yes, you need enough electronics knowledge, sufficient tools to carry out repair process and service manual of subject unit to locate defective parts.
Problem seems few capacitors and 1 or 2 band-pass filters replacement.
If you still want to repair it, please let me know to help you out.
