Volume control for JBL radio
I came up with a fix for this problem. Once you get into the radio and get
the volume control switch out, you can carefully cut the melted plastic rivits off, leaving enough to re-melt to close it back. There is a small white nylon plastic slider inside the mechanism that is the problem. The little pin on the side of the push rod slides in and out, selecting a different channel each push, making it stay in or out, depending on which little channel it goes in. Anyway, a tiny amount of white lithium grease applied to that little nylon slider fixes it perfectly. That slider must be free to move and when it gets just so dry, it refuses to move freely anymore. The greast fixes the problem. With some care, you can re-assemble the switch and remelt the plastic rivit pins to hold the switch together. I did it and it works like new now. Sam. |

Dang! That's an ingenious fix. I also took the switch/potentiometer apart,
and figured that the slider was simply worn, so I ordered a new part from Speed-O-Tach in California. Cost was about $26, but I can now turn the radio off. Good fix, Sam. Thanks for the tip.
