Schematic Request for Flex 6400 & Power Supply Issue (Not)

Is there a good schematic available for the Flex 6400?

I am asking because what I thought was an issue with my Astron 35M power supply it appears to now be Flex related. I was only able to get a few volts out of my power supply, then through the process of elimination, I determined when I disconnected the Flex 6400 from my Rigrunner power distribution unit, I got my 13.8 volts. This worked fine for years. I checked the power cable and it was fine. There is continuity between the power connectors on the back of the radio.

Has anyone else experienced this issue? Any recommendations.

    i recently had the same symptoms with my Flex 6600. When I confirmed it was not the power supply I sent it in for repair. I started the process with a help desk ticket and got very quick response from Ike that confirmed with engineering that it was probably a hardware problem. The failure was a capacitor on the PA board. Obviously shorted. It cost $35 to ship to Flex and $178 for repair, complete test, an update to all Flex issues that in my case was a new SIM card and return shipping. Flex turned it around in 3 days. Shipping UPS was 3 days in and return each way.

    I was happy to get a complete verification of the radios as new performance. It was worth the money and very happy with the results. I would be concerned if I did the repair myself I would create another issue inadvertently.

    I appreciate the feedback. I will eliminate the cables and rigrunner and see where the issue is. I an not one to reach for a solder gun. As a last resort, I will have to box it up and let Flex do their magic. I am glad you included the price and that they did a good job for you Bill. I will post the final resolution once it is determined.

    I had a significant voltage loss on transmit as measured by FR stack and the K9DUR meter. Removing the distribution block eliminate most of the loss.
