I got the sams for model# D7AF-19A241BA. It seems correct.
Thinking this was a floating ground problem, I put the board back in the metal case. All I got was static after that on FM, silence on AM. Took it back out, manually hotwired all chassis ground points, and it's picking up the same station on FM. On the very top of the AM band, I get a whisper of a station. I've come to find out that it's receiving (the FM station at least) through the chassis ground. Hooking the antenna wire I've been using to chassis ground improves the signal.
I've ohmed all the tuning coils. None are open, but I think my meter is a little off, read most of them a bit high resistance. Replaced one electrolytic that feeds the input to the multiplex decoder IC - it looked funny - no difference.
Can someone please chime in and tell me what section I should be looking at?
