I have a BirDog that I used when I worked for DTV awhile back and I can't seem to get the LCD to display anything. It beeps and I can navigate the setup menu via the online PDF. I am unable to tell what version it is. I hit the on button and it beeps as if it's on, then a second later it beeps again, kinda like the error beep. First set of beeps is slow and the second set is faster, then it powers off. Does anyone know what the beeps are referring to>? The battery is good and I can get the display to lite up. Has been stored in the case and in the box. Any help would be appreciated
