when i put the power on the door switch chatters then falls silent but it doesnt allow me to go anyfurther none of the program leds light up is it a faulty door swich or something else idea please

i took the interlock apart and manually made the connections but still nothing so it looks like its the pcb in my opinion or does it need a signal from the coil to the pcb to say its made? the coil is off on rapidly that what the chattering is if something is blown on the pcb is it repairable or will it mean a new one and how can i identify the real problem without wasting money

This could be a door lock or a door lock that has blown something on the main pcb.Difficult to diagnose 100%
