ICF-C1 Clock runs fast
Hi everyone - my ICF-C1 clock radio runs fast, gaining about 1 minute and 20 seconds every month. I cannot locate a schematic for this clock radio, so I am unsure if I can modify an RC/crystal circuit to adjust the timing or whether this uses the 60hz mains frequency as a reference. Has anyone had any luck in locating a schematic diagram or in replacing a resistor or capacitor to have more accurate time? Technician with 30 years experience here, just looking for a diagram or helpful advice.
Thanks,
Rick

same problem. mine is about 1:30 per month. pretty close. there is nothing in sony support that acknowledges or addresses this.

So no luck in finding a circuit diagram for this clock radio. The clock chip is a LC87BB08A-5CD7 but I cannot find any pinouts for this chip. Does anyone know a good location to view, or does anyone have a datasheet for this chip? None of the other Sony service manuals I looked through, that actually have a schematic and a parts list, use this chip.
Thanks!
