This STR-V4 doesn't have an SM online. TheV4L is there but the tuner board is different. I checked and the STR-V3 has the same tuner board as the V4 I have. I'll attach some shots of it. Full manual is on HFE: https://www.hifiengine.com/manual_library/sony/str-v3.shtml I understand that a tuner probably needs alignment all these years after it was built but I'd like to see if I can get that nice red stereo indicator to light up again without that service which I can't do. Thanks for any recommendations on making the lamp light again. The bulb is good and has been tested. There is no voltage at the Stereo Lamp connection.
