Hi,
Everythings works except the tuner - it suddenly broke a few days ago.
When I set the receiver to search for radio stations in its "automatic
tuning mode", its frequency counter just counts continuously through all FM
(and AM) stations and doesn't seem to find any RF signals at all. An
external FM antennae is attached, and has been working in those location for
a year. A walkman in the same room picks up all these stations now. So it
looks like the digital computer portion of the receiver is working fine, but
the RF Front End seems to be broken. I've got the service manual, but didn't
see anything obviously wrong when I poked around with a voltmeter. The
interior was very much dust-covered - I cleaned off much of the dust with
some q-tips. A few days later, i.e., right now, the tuner started working
again. But now I know it's flaky - it didn't work for almost a week.
Any ideas?

thanks,
js.
