Delco (BUICK) 7305534 No FM sound. AM works fine.

Hello All,
I'm just testing out this radio. There's no sound in the FM position, however AM is working quite well. The amplifier sounds good. It was in the FM position when I first hooked it up and heard the "thump", indicating that the amplifier is working fine.
So what parts usually fail in the FM circuitry in this set? The main PC board is warped in the back, so maybe a land is also warped or broken. I'll check, but I think that the FM board is the smaller board in the middle, if I remember this set correctly.

Thanks,

Dave

Hello All Again,
I flexed the board with a screwdriver handle and the FM came on. So the visual inspection works here. Now I have to take a really close look to find the loose connection.
