Hi all ,

I needed a small 5 digit LCD but I couldn't find it . I bought a counter (like picture below) and opened it . I want to drive the LCD but I don't know how to do it . I attached the counter and it's internal board . the Via in internal board is connected to the LCD .

please help me .

 

Well it looks like the counter is controlled by a custom die IC. I am guessing it has no communications in or out of the die other than the buttons and the actual pins for the LCD. I would suggest desoldering the LCD and start looking for a part number or reverse engineering the pinouts.
