I have an Rci2990 that was working perfectly. I moved it from one room to another room . Plugged it in and nothing on the face works . No lights on frequency counter , key pad , or meters . The frequency counter is also blank and it doesn't receive or transmit. Only white noise from the speaker .The tx light comes on when i power it up and the cooling fans are working . Ive checked voltage to the board and also even tested it with another power supply . Anyone has any ideas of where to start on testing . Thanks in advance
