Other than the earphone jack itself, I'm at a loss. Maybe the circuit diagrams in the service manual could help. The fact one channel works would...
Use a toothpick to press on the cables connections and see what that does. Also, the soldering on the adjacent SW 1 looks dodgy. I have one where...
Funny, someone selling an Aiwa HS-J600 with a remote control. The J-600 never had a remote control, and plugging the remote into the microphone...
I've worked on 6 of these now, and channel-related audio failures are common. The first step is to see if the problem happens with both the radio...
The capstan and pulley bearings in the Aiwas I've had apart, consist of what looks like a chrome steel shaft through a brass bushing. There is...
