The Mystery of the Sanyo Clock Revealed...

[superlew]

Rainy day at home, thought I'd give your clock repair a go. Took my time getting apart. Wasn't exactly sure what to use or where to put 'shim' so just put back together. Turns out it worked. Happy happy joy joy. And randomly I actually got my not working 1 to work. Although my setting buttons not exactly working. Can't set hours. Either way its working. Wicked! Cheers

If I recall, mine was doing the same with both time settings. I cleaned the clock switch and the contacts for the time settings (hour & minute) and, to this day, it's the most accurate clock in the house. You'll have to disassemble to get at them, but they're really easy to clean.
