[TenTec] Dead again!!

[AG2A]

I went into the shack and the Omni 6+ is dead again...No receive 
audio,can't change modes,can't enter frequencies. I try a partial reset and 
get normal receiver noise while the clear button is held,but, all goes dead 
again no matter how long I keep the clear depressed. I tried a total reset 
and nothing changes at all, no receiver noise or anything. Has anyone had 
this problem or is my club gonna be disappointed for field day?

                                         In a jam,
                                                 Tom - AG2A
