Batboard

I have an MCS2000 VHF high power model II with a control head backlight failure. Tried all the usual swapping of control heads and cables to isolate the problem to the radio. Any suggestions on where to look from here? Everything else seems to work as it should.

Thanks

I neglected to include that the receive activity light and Tx llight also do not work. Anyone have any similar issues or suggestions for a fix?
