Hi, I got an LCD digital clock with a AA cell supplies, but the LCD is now dark, and the soft circuit linked from PCB is broken as well.
Any one help to turn to 7-segment LED 4-digit display (maybe drive by extra transistors) connect from 36 terminals on PCB.
Thanks so much

Unless you know the pinouts of the LCD and pcb I think you're stuck

Some things are possible but life's too short. As said. Buy a new clock.

My opinion is :
Buy a new compatible LCD screen because you don't know what is the pins configuration to replace it with a simple 7-seg display set .
Fix the broken path

I don't want to repeat what have been said before, but seriously, the time it will take you to fix that is not worth it.

Now, if it's just for the fun of repairing/building stuff, well.. building a new clock from scratch may even be easier! (and more fun!)
