Please try this: connect "Clk Out" to "Ext. Clk In". If then the module is
working probably the switching contact of the "Ext. Clk In" socket is worn
out. You may try to "repair" the socket by bending the metal part of the
switching contact a bit.
Otherwise the internal oscillator is defective and the module has to be sent
in for repair (or you try to replace the cicruits of the high speed vco).
