I agree that flexing the antenna connection may get it to go back on temporarily, but it may not be that connection that is the problem. (I'll explain in a moment.) Mine does this also - I've had it out and apart more times than I can count.

If I pull the radio out of the dash (still plugged in) and flex the antenna connection, it comes back on. It usually does not stay on when I push it back into the dash.

As I said, I've dismantled the radio on the workbench a number of times, connected a surplus antenna wire and tested continuity when flexing the connection. I even replaced the end of the antenna wire with a plug from Radio Shack. There is no break in the antenna connection itself.

What I suspect is happening is one of the other internal connections - maybe the base-circuit board to back-circuit board - has the problem. When you move the antenna connection it flexes something else somewhere. I've tried bending the pins a tiny bit on that board-to-board connection to no avail, but I have not closely examined the solder connections yet.

It's just beyond the limits of my testing equipment to test further at the moment, though. I simply need time and a spare speaker.

If I figure it out I'll post something here.

Meanwhile, the CD player still works ...
