GE JVM1740SM1SS Dead

My microwave quit working, there is no lights or display at all. I have checked the power coming into the unit, OK, also checked the power in & out of the SN-UF12V card that hold the 20A fuse in & old OK and the fuse is OK. Also checked the HVT on going ionto the PCB board and thats OK, dont know what to check next.
