I built your circuit and tried it out. It drove the LCD to where instead of individual characters, all the elements were powered on. It must of done something to the circuits on the LCD board because when I removed the oscillator and powered up the calculator, the LCD was working perfectly. I'm not sure what happened, but I now have a working 41C which is now being converted into a 41CL. Thanks for the help. |
