Sounds a lot like an unsoldered or poorly soldered connection. You could 
just go over the RF board and reheat all of the solder joints, adding a 
bit of fresh solder (mostly for the flux).

It could be an intermittent component, but it's more likely a solder joint.

If it will stay broken long enough to use the signal tracing technique 
described at

you may be able to find it that way.
