Hello everyone,
I’ve managed to clean up a Panasonic RC-7589 that was really dirty inside — clock is up and running and working like a charm (thanks to the motor oiling and repair videos ) and the light bulbs have all been replaced. So things are improving… Unfortunately, the radio is a different story. AM reception seems poor compared to other similar era clocks and I can tune in a few stations. FM reception is pretty much nonexistent. I get static but can’t find anything up and down the dial but static. I’ve carefully looked for loose connections, leaking or fishy looking caps, and used contact cleaner and all switches and pots. I have zero experience troubleshooting the radio circuit beyond these simple steps.
It appears that the unit uses the AC power cable as an antenna but I haven’t chased down the exact wiring yet — a broken connection to the power cable would be my next check as I could potentially see the symptoms matching that of a missing antenna.
Does anyone have any suggestions on troubleshooting the radio?
Thanks for any suggestions you might have.
