Hi, I hope someone can help me I have built an automatic trasnfer switch for genset it makes all necesary to turn on the motor of the generator when the mains goes down. The circuit has a CPU and an LCD 2x16 Truly the problem is that sometimes the lcd after hours of working ok hangs up and the display becomes black ( the codep still works ok) I put big capacitors in the power source (4700uF - 7805-4700uF) but the problem persists
