Remove and reseat the RAM board. Also, check the battery voltage on it. What does the display show? It it normal or gibberish?Any good techs that work on them? Mine has no TX or RX. It was a working radio then one day nothing
New means nothing, if the headers it plugs into are oxidized, which is why I suggested you remove and re-seat. I have seen this before in the Icom's that use the RAM board.RAM board is brand new
