Hi, my name is Mike and I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. If you have a multi-meter and are familiar with checking voltages then check to confirm that there is voltage at the main PCB. If you are not familiar with checking voltages but you are quite handy then you can also visually inspect the PCB for obvious damage and also confirm the green light on the PCB is lit when the power is on. It is very likely a failed PCB and will need to be replaced.
