My best guess is that you neglected to solder a pin or have a cold solder
joint on U4 - the PLL synthesizer. Quite often an un-soldered pin will work
for a year or more, then oxidation causes it to go intermittent and then not
work at all. Check solder connections for the parts on the top half of
sheet 1 of 4 of RF Board.
Next I would check voltages and that should give you an idea of where there
could be a problem.
