My icf-sw77 was working fine than somthing went wrong.
All the control functins work except the signal strength display is somwhere in the middle. I can tune and do everything else but there is no audio. I am 99.9% sure that the audio amp is ok I tested it with a signal generator.
I think a portion of RF/IF is bad that is becaus the signal strength display doesn't move.
Any idea what is wrong? Does anybody have copy service manual.
I called Sony, they don't service this product.
