The Recieve Audio on my KX-155 w/GS is weak to non existent at times so I had it serviced 2 years ago, but the problem did not go away so I swapped it out with a spare KX-155 (non GS) that was working great until recently.

The spare KX-155 display now goes blank after a few minutes, but that is another issue and now I have 2 radios that have issues. The spare KX-155 does not have a bad display itself, there is something else causing the display to go blank and stop working. If I cycle power to the spare it comes back to life and works perfectly for a few minutes.

Does anybody have any troubleshooting suggestions on the KX-155 w/GS that has a Recieve Audio issue? I keep thinking it is a connector mating issue because the unit was serviced and sometimes receives correctly, but not consistently. I have cleaned the tray connectors and the radio connectors. I have tried varying the radio seating in the tray with no luck. Any ideas? Thanks
