I was working on an XPR6550 that had intermittent transmit issues. The issue was traced back to a loose rf jack on the board (4 broken solder joints). Upon reassembly of the radio, the display comes on as normal at first, but then the backlight turns off, none of the buttons function (along with the channel and volume knobs), and the PTT button activates the emergency function. Anyone have any ideas to what could have gone wrong?
