LED Watch Repair
The complaint of my LED watch was no light. It seems like no power and could be due to sign of low battery problem.
The first thing to do is to open up the back cover and start checking it-see the photo below:
I took out the battery and check with my voltmeter and it was measured good- 3.06 volt.
Next I checked the two buttons for good contact and both contact buttons were checked to be good.
After checking the battery I found that the crystal oscillator one of the leads seem to be rusted and not in good contact with the circuit board. I took out a penknife and scrap off the rusty area applied fresh solder onto it-see the photos below:
I really got a surprised that my watch was working again-see the photo below. This means in the future if your watch is giving problem it can also be due to bad crystal oscillator if the battery check to be good.
