Sounds like one of the LDMOS devices may have let out the magic smoke.

Contact support so they may properly troubleshoot the issue with you.

Disconnect the power (red and black) cable between the amp head and the power supply and turn the amp on. Is the "HV" light on the power supply still RED? If so, the power supply is bad... send it in for repair.
