Hi Windell, I’ve replaced C3 and C6, played with the mechanical side of things (tapping, bending LED’s etc) and it still does it..I’ve checked and double checked the layout, the other capacitors, swapped IC’s (as I’d mentioned before) and I can’t see anything untoward. I’m stumped. It’s probably something obvious, but in my defense ;-) I just finished the other bulbdial and it’s working fine…any chance I could send the board your way for a look?
