Hi folks,
I've recently acquired a Sony GX9ES from an online purchase. Long story short, it took a major faceplant hit during shipping, and I've been trying to asses the damage beyond cosmetic. http://audiokarma.org/forums/index.php?threads/classic-80s-black-and-rosewood-sony-str-gx9es.815736/
After setting up a few local stations in memory which it pulled in nicely, I was listening to it the other night on the CD input when it shut itself off. (That shut off may be related to a loose plug/receptacle, I'm not 100% sure, but that receptacle doesn't 'grab' plugs like the others do in my home. I've since switched to a new receptacle.) When it came back on a few seconds later, the FM readout displayed 76.0, and would only go up to 90.
Fellow member Ds2000, recognised this as being the FM scale for Japan, and probably not an actual fault in the electronics.
I've tried various 'tricks' suggested as far as clearing out the memory by holding the power button after power-up, and stuff like that but it has not returned the tuner back to US mode 88-108. I've also had a look at the board itself, and in my limited electronics experience opinion, don't see anything obviously wrong with it. I've unseated and reseated all plugs in an out of that board, but that did not resolve anything.
Perhaps any of you might know the trick to switching older Sony tuners back to US FM scale? Please let me know if you've got any ideas. Thank you!

That’s the Japanese tuning scale. How odd! There must be a dual mode tuning chip inside or something like that.
