Before you start with the scalpel are you sure the statons(s) are sufficiently strong to allow stereo tuning?

Sorry for the slow response, had a prob with my FixYa login/pw--all correct now [great response on that]. On to business--the station I am using for test registers 5 bars on SS LEDs on my Proton 440 snaps into STEREO immediately and comes in on great audio [same antenna/etc]. Proof enough for me. The HK AVR20 does not light up the STEREO LED, in stereo mode [and sad it doesn't have a SS LED bar set], but works perfectly in mono. I am going to attempt an alignment [if possible], but only have a [very good], VOM / 60MHz DT scope / signal tracer. Found a HK bulletin [Service bulletin # 9601 -January 1996] and going to check that parameter [for FM center tuning alignment] in addition to what general alignment i can perform. Still think it is "something" simple, but haven't had the time to take the "lid" off/examine with loupe lens/light. The owner is a 45+ old "conservative" who is a co-worker I admire/respect--he says he hasn't even come close to even "accidental" abuse, and I believe him [me--33+yrs business management--great character judge]. So we shall see, and again, thank you for your [quick], response, any further ideas, do not hesitate--they will not go un-noticed.

I have the exact same problem! I added a powered antenna and when I turned it back on, nothing. I opened it up a checked all the fuses and they were alright. I disconnected everything and just used the speakers and still the problem persists. Have you found a solution?
