When I press the detonate button, the clock immediately lights up and makes noise. There is no countdown from 10 – 1. The alarm clock is in defuse mode (I tried it in all others just in case). Everything else is functioning, I can change the time, etc. Sound and all LED’s are working. Double checked my solder, went over everything. I paid special attention to the chips, as that is where I assume this function would be located. Any idea where I should focus my efforts?
