Another component to check is the wall-brick power supply. I have a clock with a 4-amp 5v supply, it worked fine for over a year then started acting strangely. Under load the wall brick was only putting out 3.5v, no load it was up at 5v. I replaced the wall brick and all is well. http://transistorclock.com/cal/index.html
