Open up the radio, but not the sealed RF tuner module. Instead, you can probe on the pins from it to see if this is really the problem or not.

You'll have to poke at the datasheet for the RF module (microtune 1384 ufc/wfc, or 1385 ufc) to see which pins mean what, but I could get FM audio from an earlier output when probing around the dead component.

Eg. on the 1384wfc, pins 15-18 -- one of those had (muxed) audio, but the final output did not. Thus the failed component was between those two pins, whichever two they were.

Cheers
