When the ps is activated the radio displays a green light for a second or so. Does the green light mean anything?
After the green light goes off and I press the radio button the radio displays the message "Shutting down... Error PSH1V5-4.10" and a red light flashes continuously. Does have any further meaning?
After I press the radio button again the message is "Shutting down" and a very brief additional message that I could not read and shuts down. Does that sequence have any further information?
measure voltage at the power poles with radio off turn on and watch the voltage do this before the above and after. please respond back with results. 73's K4ATR
So, I did not have this problem, exactly, but I did have one that was power related. I run a lot of AM and a few people commented that they heard a very slight bit of distortion. That got me looking. While using the stacks program I noticed that the internal voltage was dropping .7-.8v @ 100W out. My power cord needed to be ~ 6ft long. Three simple fixes took care of the problem. First, I made a new power cord using #10, super flexible silicon coated wire. I found what appeared to be a very light white film on the main fuse’s blades. I cleaned them and applied, very sparingly, some conductive silver grease to the power connector and to the forks on the two internal fuses. Now, under full load I typically see a drop of .1v, occasionally .2v. No more reports of distortion. I shared this info with FRS and suggested they consider using the conductive grease. Never received a response.

Flex-6500 Shut Down Story Update –
Thanks much for all the responses. After it was recommended by DP at Flex Radio that I return the 6500 to Flex under an RMA the radio was evaluated by the service person, GJ. It was determined that one section of the voltage regulator had failed. The output voltage then was generating only 9 vdc, not the standard of 12 vdc. Apparently the 9 vdc caused the failure of the CPU, TRX board and the BGAS. The failure in the BGAS would require extensive repairs and more repairs could be possibly found. The potential further extensive repairs resulted in the decision to scrap the 6500 and accept the Flex offer to trade any remainder parts value for the costs of the incurred evaluation. The failure a small dollar (~$25) partial voltage regulator caused the destruction of a BIG dollar (~ $4,000) Flex Radio. Yes, the 12 month warranty ended October 2018 and the blade fuse (~<$1) was left intact. RIP Flex 6500.
