Introduction
The circuit board allows electricity to flow from the battery (power source) to the LCD screen. If the circuit board is damaged, the watch will not turn on or display the time. A faulty circuit board will most likely have cracks, scratches, or bulges.
Before using this guide, test new batteries on the watch. If the battery is running low, the watch will not display correctly or turn on either.
