i have an Alinco DX70 with a flashing display. It does not happen all the time. At first i thought it was the harness between the face plate and the main radio body. I have read that these radios have had a problem with the PLL becoming unlocked due to a leaking capacitor. Is this a costly repair? I was thinking of sending the radio to Clairmont Skyline radio and tv repair for a diagnosis. Any thoughts?
