Question about Sony ICF-SW77 AM/FM/SW Radio

Open Question

My receiver ICF SW77 is sometimes dead, sometimes it is working. It seems that the Signal Flexible Board (part number 1.640.354.11) is the problem. This SFB is no more produced.

I have a old Sony ICF-SW77 portable shortwave receiver which has lost it's audio. I have replaced the audio o/p IC but still dead. I've reached the limit of my ability and would appreciate...


Look up a data sheet on the audio output IC and get the pin out labels for the pins on it. Then check to see if you have all the right voltages especially at the power supply and ground pins. Good luck.

No Battery Power


Late with this answer.... Battery tabs sometimes loose contact with signal board near volume slide, possible solution is to reapply solder and bend contacts slightly.
