FM reception is fine only the stereo reception and related indicator recently stopped. Similar but not exact issues have been mentioned in past posts, but nothing exactly like I've experienced here, so I wanted to try & get some fresh help. My trusty 9090, not DB, has worked fine for decades. I recently went in to deoxit controls and replace various lights (related post by me uploaded). Anyway, it was working perfectly with FM stereo beacon illuminating fine after all the work was done, but a couple of days later, the stereo signal stopped. FM comes in fine, both FM meters are working fine, other inputs are all in stereo as it should. Stereo bulb is fine. In fact this is the sole issue. Listening to FM with headphones it is in mono, so the indicator is probably working properly as there is no stereo signal. Reading past posts suggest such things as: adjusting VR03 muting/stereo threshold and VR04 19kHz vco both on F2549 VR01 stereo auto noise on F2550 none of these suggestions worked, in fact I adjusted back & forth all the VR's on the tuner boards with no change in performance. any further suggestions? Thanks.
