I managed to save this clock/LED display from trash. Upon further inspection it showed that the inductor and capacitor in the power supply went to electronic heaven
. After replacing them it started working and at my surprise the date was correct, but the clock was 54 minutes late. After googling I didn't find anything usefull on how to reprogram RTC, so I am looking for someone to help me with reprograming it
.
Also if anyone is interested in it, please contact me because I am slowly running out of place for all my salavaged items
