Hi,
I have a Pioneer sx-727. I'm the original owner over 40 years.
Recently developed fm problem.
Loud crackling sound on fm station and then station drifts. No noise
at all between stations.
AM reception also not good, background buzz, humm between
stations on AM only. Unit works perfectly with CD and other inputs.
Any ideas what my problem might be? This all started a couple of weeks
ago,
when I noticed that signal strength meter was not illuminated, I
assumed just bulb burned out.
Tuning center meter still works. Any help would be appreciated.
Thanks.

Hi Tony,

If you can hear the stations at all and they're randomly drifting try
squirting some tuner shower/contact cleaner into the tuning gang where the
rotating shaft contacts the bearings. There should be two or three bearings.
Then, move the tuning dial quickly from 88 to 108 back and forth several
times. You might have to spray several times to get the most benefit from
the cleaning. Did that help?
