OK, so I search for Yamaha tuner problems (intermittent FM) & find the
threads for LC7210 problems. I replace the IC for $21.50 & same
problem! Tuner works for long periods (hours) & suddenly the signal
strength drops to "0" & white noise only, no FM stations. AM & all
else still work. I leave the unit on & it just as suddenly starts
begins working again. This is really a great receiver & want to fix
it. So: Does any one have a Schematic and any suggestions from the
experts?
Thanx - Bob
